      A Few Simple Rules   05/22/2017

      Sailing Anarchy is a very lightly moderated site. This is by design, to afford a more free atmosphere for discussion. There are plenty of sailing forums you can go to where swearing isn't allowed, confrontation is squelched and, and you can have a moderator finger-wag at you for your attitude. SA tries to avoid that and allow for more adult behavior without moderators editing your posts and whacking knuckles with rulers. We don't have a long list of published "thou shalt nots" either, and this is by design. Too many absolute rules paints us into too many corners. So check the Terms of Service - there IS language there about certain types of behavior that is not permitted. We interpret that lightly and permit a lot of latitude, but we DO reserve the right to take action when something is too extreme to tolerate (too racist, graphic, violent, misogynistic, etc.). Yes, that is subjective, but it allows us discretion. Avoiding a laundry list of rules allows for freedom; don't abuse it. However there ARE a few basic rules that will earn you a suspension, and apparently a brief refresher is in order. 1) Allegations of pedophilia - there is no tolerance for this. So if you make allegations, jokes, innuendo or suggestions about child molestation, child pornography, abuse or inappropriate behavior with minors etc. about someone on this board you will get a time out. This is pretty much automatic; this behavior can have real world effect and is not acceptable. Obviously the subject is not banned when discussion of it is apropos, e.g. talking about an item in the news for instance. But allegations or references directed at or about another poster is verboten. 2) Outing people - providing real world identifiable information about users on the forums who prefer to remain anonymous. Yes, some of us post with our real names - not a problem to use them. However many do NOT, and if you find out someone's name keep it to yourself, first or last. This also goes for other identifying information too - employer information etc. You don't need too many pieces of data to figure out who someone really is these days. Depending on severity you might get anything from a scolding to a suspension - so don't do it. I know it can be confusing sometimes for newcomers, as SA has been around almost twenty years and there are some people that throw their real names around and their current Display Name may not match the name they have out in the public. But if in doubt, you don't want to accidentally out some one so use caution, even if it's a personal friend of yours in real life. 3) Posting While Suspended - If you've earned a timeout (these are fairly rare and hard to get), please observe the suspension. If you create a new account (a "Sock Puppet") and return to the forums to post with it before your suspension is up you WILL get more time added to your original suspension and lose your Socks. This behavior may result a permanent ban, since it shows you have zero respect for the few rules we have and the moderating team that is tasked with supporting them. Check the Terms of Service you agreed to; they apply to the individual agreeing, not the account you created, so don't try to Sea Lawyer us if you get caught. Just don't do it. Those are the three that will almost certainly get you into some trouble. IF YOU SEE SOMEONE DO ONE OF THESE THINGS, please do the following: Refrain from quoting the offending text, it makes the thread cleanup a pain in the rear Press the Report button; it is by far the best way to notify Admins as we will get e-mails. Calling out for Admins in the middle of threads, sending us PM's, etc. - there is no guarantee we will get those in a timely fashion. There are multiple Moderators in multiple time zones around the world, and anyone one of us can handle the Report and all of us will be notified about it. But if you PM one Mod directly and he's off line, the problem will get dealt with much more slowly. Other behaviors that you might want to think twice before doing include: Intentionally disrupting threads and discussions repeatedly. Off topic/content free trolling in threads to disrupt dialog Stalking users around the forums with the intent to disrupt content and discussion Repeated posting of overly graphic or scatological porn content. There are plenty web sites for you to get your freak on, don't do it here. And a brief note to Newbies... No, we will not ban people or censor them for dropping F-bombs on you, using foul language, etc. so please don't report it when one of our members gives you a greeting you may find shocking. We do our best not to censor content here and playing swearword police is not in our job descriptions. Sailing Anarchy is more like a bar than a classroom, so handle it like you would meeting someone a little coarse - don't look for the teacher. Thanks.

      Moderation Team Change   06/16/2017

      After fifteen years of volunteer moderation at SA, I will no longer be part of the moderation team. The decision to step aside is mine, and has been some time in the works but we did not wish to announce it in advance for a number of reasons. It's been fun, but I need my time back for other purposes now. The Underdawg admin account will not be monitored until further notice, as I will be relinquishing control of it along with my administrative privileges. Zapata will continue on as a moderator, and any concerns or issues can be directed to that account or to the Editor until further notice. Anyone interested in helping moderate the forums should reach out to Scot by sending a PM to the Editor account. Please note that I am not leaving the community, I am merely stepping aside from Admin responsibilities and privileges on the site.

New JS9000

76 posts in this topic

"The new ADMIRALTY 30 OD is now in production and the first boat in the US will be available for inspection and demo sails

in Long Beach March 17 & 18.

The new boat is a much-improved version of the original JS9000 with more sail area, winged keel and fixed sprit added to

improve both upwind and downwind performance.

The ADMIRALTY 30 OD can be sailed with one to three crew - optimum for racing is two or three on board depending on

conditions.

My best (JS9000) is 16.5 kts on a spinnaker reach with two crew (myself and one other). We had 18-20 kts true and the boat

was so stable I could steer with thumb and forefinger. It's a hoot!

The ADMIRALTY 30 OD offers even better performance and is ready for you - my web site has not yet been updated so I will

be happy to answer any questions or provide more information.

Just let me know - and if you are in the area, please plan to visit us in Long Beach.

The President of Admiralty Yachts and John Swarbrick will be there to provide everything you want to know about this great new boat!"

Lose the drag on the keel and it will probably do more than 16, might even be as quick as the RLAR!

I am glad that this wonderful boat is back in production. I wish great success to it.

Did you see, the mast is behind the keel? And it seems to work.

I agree - that looks like a lot of drag to me

 

 

 

I hope these guys get the boat squared out this time around - I really like the concept - especially being able to easily doublehand/singlehand.

I agree it appears it may be draggy but i retain only a hint of skepticism,

Arrow with that keel is the fastest boat downwind in a breeze in the 30's at the SASC, also borne out against some sportsboats in the Audi. The more it blows the larger the gap (ie when the effect of any drag should be multiplying) , it simply doesnt seem to have any effect at all.

 

remember the designer was right at the top of the most intensive development of the winged keels , the '87 Fremantle AC,

there would have been unlimited amounts of drag and tank test data back then, every team had two or three boats and years of incremental testing and development.

 

also what you are seeing is not what the water 'sees', there is one shot in there from ahead, i.e. from a 'frontal area' perspective it shows the wings add bugger all to that, anything after the water is pushed aside is merely how the turbulence and vortices are dealt with.

in any case it would need to be justified against gains upwind which is a hydrodynamics topic in it's own right.

TS it does well more than 16kts dw, similar to what we're used to doing

Hi Bill & John,

 

I would love to get a ride on the new boat. As you may know, I've been pulling for this boat for a long time, and have been looking forward to seeing it on the water.

 

Unfortunately, the weekend you have planned is opening day weekend in Marina del Rey, & it's our 75th Opening Day, so I'm completely obligated on Mar 17 - 18. Are you going to be on the water before or after that?

 

Thanks!

we both sail on J'ns boat Arrow for 2 seasons odd, (3 crew); THAT is the same shape and style of the bulb Christian, also the bulb weight on the doc checks out

 

It looks very very very similar, dja see the other pics in the Images link? i'd be a little surprised if it were not the exact same casting.

John,

 

Could you please tell us more about who the builder is, what experience, resources etc?

 

How many hulls has the new builder built?

 

Do you have a spec and pricing sheet?

 

Delivery schedule?

 

Warranty?

 

Thanks.

Dear Sir,

 

Quite an interesting comment - seems you are right on top of things out there.

 

As a matter of fact, I have actually paid my own way for most of my 63 years.

 

You may be interested in knowing that I did not post the information you seem to find objectionable nor did I ask anyone to do so. I don't even know who "geronimo" is.

 

As you might have noticed, I have posted on SA maybe two times in the last three years and it would appear that my direct answers to direct questions from one of your readers has been expunged, reducing the total to one.

 

My words were copied from a mailing I sent to a list of people who had previously expressed interest in the boat. One person receiving my mailing apparently thought your readership might actually be interested in the information.

 

As a matter of fact, I will be encouraging Admiralty Yachts to consider advertising on your site as part of an overall program when I meet with them in March. They are new to the US market and need some guidance as we tend to be a bit different in our attitudes (and latitudes) - which is graphically illustrated on your site.

 

It would be helpful to have pertinent information to present to them - similar to what I have received from other advertising resources. After all, those who want to sell their services to those who want to promote their business should sell their services. Honey vs. vinegar? Information vs. barbs?

 

Perhaps I should apologize - unfortunately I don't know what I would be apologizing for. Living?

 

Or reading SA maybe once every couple of months? Someone brought this latest topic to my attention - or I would not have seen it at all.

 

I like to sail and I love my boat. I do not have a financial interest in or gain from the successful promotion of boats. Hence "promote your business" is a non sequitur. My business is having fun and encouraging (and sometimes helping) others do the same.

 

Being retired is a luxury I have enjoyed for some 15 years now, allowing me to sail when and where I choose, paying my own way as I go.

 

I am John Burgess, johnburge@gmail.com , 770-965-8500. Please feel free to send any pertinent information regarding SA advertising opportunities that you would like for me to pass on to my friends at Admiralty Yachts.

 

Thanks!

Good job John.

 

Back to the boat. There seems to be a number of significant differences. In fact, I'd say the only thing that's just the same as Arrow would be the hull shape.

 

Looking at the Admiralty 30, compared with the more powerful Arrow, I'd say Arrow would be quickest round the track. However, Arrow is now far more labour intensive than the Admiralty 30. Our mast head kite for example tears my fucking hands apart, but we're sailing approximately the same boatspeed as true windspeed now downhill (up to about 18kts where true wind begins to overtake boatspeed). We've seen low 20's in boatspeed, and are still unsure where the limit is.

 

The owner has installed hiking straps, and we've had to bring Rocket (our new mainsheet hand) on board - who provides plenty of righting moment.

 

Admiralty 30 can still be sailed single handed, I doubt anyone would be game to try that on Arrow in anything over 15kts.

 

Mind you, I suppose you could add hiking straps, mast head kite, taller rig, lower boom, longer prod etc... to the A30. Then it would be close eh.

I am not sure I am supposed to be posting an answer, but let's see what happens.

 

 

When asked for my input, I strongly encouraged Admiralty to finalize the design once and for all and stop tweaking the boat.

 

 

I have not even seen the new boat yet but have been corresponding with Admiralty for about 18 months. I am retired, don't have anything else to do, and tried to help John Swarbrick because I really do enjoy my JS9000. Then Chia asked me to help get Admiralty started in the US.

 

 

The only way a builder has a chance to succeed with small boats (and low margins) is to keep it simple - i.e. all boats identical. This approach might even lead to a OD class someday if the concept of a fast (and fun) two man boat catches on. Maybe we can get some of the locals out to Long Beach March 17 & 18 to give it a try and report their findings back to the forum.

 

 

Arrow is a great project boat that is proving the design concept valid. You have pushed beyond the edge of the typical sailor who wants to go sailing on a "normal" boat and you are obviously having a great time doing it!

Teaky, are these numbers GPS or on boat log ? I've noted that the boat is quick downhill but you're hardly tearing through the fleet doing 4-5 knots quicker, we all touch on good numbers in S30 boats on the downwinds, but you guys consistently doing windspeed ???? Big claim, you should have overtaken Tasty by the bottom mark at GI last Saturday at those speeds.

Actually, I should say up to 16 rather than 18.

 

On Sat Tasty was doing about 1kt slower than Arrow downhill (according to Jason, 13.1kts) - that lead they had by the top mark was too big that day as we did 13.9. Did you record much more than 14kts windspeed?

 

But the numbers are on the tacktic, which although it has recently been re-installed and calibrated could be a little off. We're paying close attention to the numbers at the moment, and recording them on a dictaphone so that later we can write out polars.

 

When we have flat water, we're usually looking at the gusts on the water, sometimes we have to heat up to reach one, as it's constantly on our shoulder! We try to keep the same gust all the way downwind when we find the right one. We're usually getting about 3 gusts for a run at the moment. Few more on Sat as it was so shitty up at Manly.

 

Ideally we'll traverse the same gust the whole time, gybing at the edges.

But what jas is talking about is a one off number, I can impress anyone with hitting the max speed button at the end of a day sailing and say we did 14 knots ! Distance over time really is the only indicator of a truely fast boat, I've had a Bavaria cruising shitter hit 18.5 knots offshore, doesn't make it a fast boat. Anyway back to thread on the JS9000/Admiralty 30, you've got Audi and 3 more Amateurs S30 races left to show us what the Arrow can really do.

I could have sworn I saw pictures with a very different set of winglets - maybe that was the UK (?) version and not the Teaky Toy
yeah not Arrow, there is a winglet keel with Swarbrick in W.A. and the UK thing was a stolen version of the design by one of those Assy dinghy builders over there that was shut down legally, you may well have seen a pic from one of these, like the sports8's foils

 

stig , can assure that Arrow could do SOG at 4 or 5 more than a 'accommodation' 30 at times, if enough pressure, but not often enough in a 'real world' situation; must be tempered by the fact she's tacking at fair angles and most courses /breezes/islands/headlands simply do not allow a perfect situation or enough runway to exploit that

 

in theory on open water at +15knts you could lay a triangle (approx +-60° corners) that could emulate the perfect Assy angles and force yachts symm. poles onto the forestay and struggling a bit

 

The harbour is the FULL gamut of angles, conditions and considerations 'eh

.

We hope to Mate.

 

The top speed was the only indicator for comparison that Jas put up. Clearly, an average speed over distance downwind would be better. And using a GPS.

 

Tasty does seem about a kt slower than Arrow downhill in most conditions. Problem is (for us), she's faster and higher uphill by more!

wow.....the irony...

 

when the same questions were asked of the ed's pet project, the "builder" couldn't even type his own name, much less provide coherent answers......and the boat turned out to be a huge development headache (surprise, surprise)

 

now somebody answers a few basic questions about another interesting project, and the post gets deleted....I suppose this could be a very good omen........

 

oh well, good luck with the boat.......cool idea to have a 30ft sportboat that can be sailed by 3......

Teaky,

On Arrow's mast head kite what kind of mast stiffening did you have to do? I see there is a backstay with a whip but is there anything else? On our boat here in New Orleans we are always trying to pull more speed out of the boat. We have toyed with the idea of putting a masthead kite on it but questioned the rig strength. Our first mast broke during a tropical storm here and it has been replaced by the CST MKII mast I believe. And could you post some pics of Arrow with the masthead chute up? The one above is small.

 

Thanks

Hi all. I am the buyer of production hull #1 in Long Beach. I am happy to answer any and all questions. I have been off computer all weekend as we are gearing up for a major remodel (quid pro quo for the new boat) and have been visiting home design shops, tile outlets and plumbing fixture stores, ad nauseum.

 

First of all, what does it rate? PHRF SoCal, in its infinite wisdom gave it a 60 bouy rating (42 RLC and 39 OWC). I think they may be on drugs, but we'll see. I was hoping for more like 78 or 84.

 

Sails - did not come with the boat so I am having them made by Harry Pattison at Elliot-Pattison. I am sure Harry is happy to answer any questions. The main and jib are Load Path and I am getting a code 2 runner and a code 1 reacher.

 

Dimensions: I - 28.05 ft. (8550 mm). J - 12.23 (3728), P - 33.69 (10350), E - 10.33 (3150), Ic - 31.50 (9600), Jc - 16.40 (5000).

 

The builder - Admiralty Yachts has been around awhile. I understand that in addtion to pleasure craft, they build patrol craft for the Singapore security forces. The boat is GRP with Herex-80 foam core. The build quality seems very good. They identified a couple of areas they wanted to strengthen, based on some test sailing John Swarbrick did in Singapore a few weeks ago in a decent breeze, and the parts were fabricated and Fed Ex'd to me before the end of the same week. They involved some additional strengthening around the keel box and under the mast step.

 

The boat hasn't splashed yet. We're hoping for the end of this week. Sails will come a little later.

 

I haven't received official approval to use Long Beach YC's dock for test sails the weekend of March 17-18. However, if that doesn't happen, we'll still do it somewhere in Alamitos Bay. I'll post updates on this thread (I've discussed this with the Ed and he is OK with it). If you can't make it for a test sail due to NOOD or whatever, just PM me and I'll try to arrange something at another time.

 

I've invited the Ed to take a test sail and write a review for Sailing Anarchy. I am either eternally optimistic or brave beyond words (third choice - stupid).

 

What does it cost - contact John Burgess. I have absolutely no financial interest in Admiralty or JS Yachts USA. My only goal is to stir up some interest. If a few more people get interested, an OD class could happen. To whoever asked about those who bought the earlier version - I was ready to buy Mk I of the JS9000 over a year ago, but it has taken this long for the deal to happen. Once I heard about the changes Mr. Swarbrick wanted to make, I was willing to wait. There were only about 5 of the JS9000's sold in the US, so it never really took off as a class. I hope the new Admiralty 30 version will. Like many of you, I gott tired of having to round up 5-6 crew every time I wanted to race. I like the idea of rounding up one, or maybe two.

 

Finally, to any of you who may be members of the Motion Picture Academy, thank you for voting for Little Miss Sunshine. Mrs. Bill J works for the studio and Oscars mean more sales, which means a bigger bonus (we hope), which pays for the boat.

Here in New Orleans our JS9000 with our genoa rates 84. We recieved a 3 second hit for adding the sail to our inventory.

Our sail is fitted to a fixed block, we were going to add tracks but we never got around to it, yet. And it was definately worth it. We can actually out-reach a Melges 24 (main and jib only) in 10-15. If I remember correctly.

What is the length of the foot of your genoa? With the mast set back behind the keel on the new Admiralty 30, the foot is now 12'. Plus with a higher mast, the I dimension is higher. The sail area of the jib is now 15 sq. mtr.

I dont have the exact measurements right now but I will post them soon. The jib in that picture above was the prototype sail that we had the Quantum loft here in New Orleans cut down from a Ranger 29 155% genoa. The actual race sail is a Quantum but it is slightly flatter and shorter foot length.

I likey the new js. It's a nice update.

Me too. Now lets standardise this! NO MORE CHANGES! ONE DESIGN RACING PLEASE!

 

Give the punters some confidence they wont have to upgrade every 3 years.

Just about every pic you see of these things going upwind they are on there ear.

 

Hike Bitches!

take it fr me Turks

It's UW performance is best when pressured

 

figure this for different, your'e gunnel Posi when it heels further is actually tilting to WELL to leeward, the stronger it blows, not alot of hiking gain/leverage there, especially when you consider a bulb 7-8 times your mass is way out to weather of you

 

simply there is no other way, it's a different concept, unlike other boats heeling is not the end of the world, rather designed that way

 

initially tender ( no form stability (via width) is detectable),

 

utimately quite stiff (v healthy size bulb at more plenty mo' draft the others)

 

it'll flop over, then virtually resist going much further,

To give an idea of how long the keel is, here's a picture (hopefully) of my boat's keel getting ready for the boat to be lifted on it. It is on about 8" blocks.

Here's another shot showing the boat being moved into position over the keel. This took place yesterday (Monday).

Last shot. The keel is up about 2/3. Note the keel crane. It leads to a turning block at the chainplate and from there to the winch.post-81-1172600785_thumb.jpg

Here in New Orleans our JS9000 with our genoa rates 84. We received a 3 second hit for adding the sail to our inventory.

 

 

 

GYA PHRF has the boat rated at 90.

 

 

 

Interesting logic in giving a 3 sec penalty for adding a larger jib. What is it? 100%? 110%?

 

The standard jib on a JS9000 is 80%. Isn't PHRF is supposed to allow up to 155%?

I can't remember if we got a 3 or 6 second hit for the big jib (which I think is a 150%, could be 155%). But either way we rate 84 now.

Congratulation for your new boat Bill J. I wish you hours of fast and easy sailing.

I am wondering if you have the specs of the boat. Especially the displacement and the ballast weight. And of course the new sail area.

I am also impatient to read reports on how the boat sails and how you use it.

So Christian (fullsail), has your project been in discussion here? No wonder you're interested in this new JS, you have actually build one like it ;)

Thanks.

 

I gave a lot of the specs in an earlier post on this thread. Here the others you are asking about. Displacement is 2425 lbs. (1100 kg) and ballast is 1543 lbs. (700 kg). Most of the ballast is in the bulb. The Ballast to Displacement ratio is 64%. The designers sail area is 20 sq mtrs (215 sq ft) and the jib is 15 sq mtrs (161 sq ft). The sailmaker hasn't given an area on the spinnaker yet, so the area is projected at 627 sq ft (58 sq mtrs) using (SLU+SLE)*(ASMG/3+SF/12), where SLU is luff length, SLE is leech length, ASMG is mid-girth and SF is foot length.

 

I hope to splash this week and have sails by the week of March 11. I am offering test sails the weekend of March 17 & 18 to anyone in the SoCal area (Long Beach). If anyone is interested, please PM me to let me know. I'm trying to get a feel for how many people might show. If I get enough, I think I can get both John Swarbrick and the head of Admiralty Yachts to fly in.

initially tender ( no form stability (via width) is detectable),

 

The only solution is a deeper, higher aspect keel with a lighter bulb. Better lift, better mechanical advantage once heeled, more resistance to heel past a certain angle, better through the waves and slop because the bulb is about 100+kgs lighter. Add another 0.8-0.9m to draft bringing it to 3.1m or thereabouts.

 

Wider, higher aspect winglets (more like a boomerang than a F1/11 wing) as originally designed would be faster too.

 

However, a keel like this would be harder to manage and more easily damaged on a trailer recovery if no crane. So this design is better for a broad interest class.

 

For IRC or PHRF racing it would be my choice.

Well Planaa what at surprise to see my boat SuperBlanc here. Thanks. I guess you had the curiosity to follow the link and find it.

Maybe it is time to open the discussion but it should be on his own thread. Do not want to hijack this one.

Thanks Bill, happy man.

 

As I see, the specs are quite the same than the Js 9000 except for the increase in sail area and of course the mast behind the keel.

I looked at all the pictures at Admiralty yacht and emphasize is upon lots of details. This boat seems well built and finish.

Long life to the A30.

You may want to email Chia at Admiralty Yachts - he can provide information regarding prices and delivery to any port in Australia. Chia T F chiatf@admiralty.com.sg or http://www.admiralty.com.sg/ (they still have to update their site from the JS9000 to the new ADMIRALTY 30 OD.

"The new ADMIRALTY 30 OD is now in production and the first boat in the US will be available for inspection and demo sails

in Long Beach March 17 & 18.

The new boat is a much-improved version of the original JS9000 with more sail area, winged keel and fixed sprit added to

improve both upwind and downwind performance.

The ADMIRALTY 30 OD can be sailed with one to three crew - optimum for racing is two or three on board depending on

conditions.

The ADMIRALTY 30 OD offers even better performance and is shipping now.

If you are in the area, please plan to visit us in Long Beach.

The President of Admiralty Yachts and John Swarbrick will be there to provide everything you want to know about this great new boat!"

Admiralty 30 OD: Here's a well built boat that currently rates 60, can be sailed with two or three on board, costs $50K and no one wants to go for a sail??

 

The least we could do is take a quick look and report back to the SA inquiring minds!

Hard facts: my js0000 is lightly modified: larger roach, short sprit, a bit larger jib. Best topspeed alone with 48sqm assymetric 20,2 knots gps. Best hour average 14,2 knots alone with code 0; 14,2 knots. Every season above several rides above 15 knots. The Oslofjord is no hardwind area. Difficult to race to its handicap since the fjord leads to leeward windward courses. Very difficult to find a more fun keelboat to sail one or to up. All the best of luck to Admiralty30. Hope it will go better this time around!

I love the concept, but wish they had a smaller version with less draft requirements. I'd buy one in a hearbeat!

Agree about the concept and I'd buy one this size but not for sixty five grand. I know you can spend more on some other boats but that to me is a lot of duckets for a day sailer.

Jerryd how much smaller than a 9000, and what draft?

Would draft be an issue if this smaller version had a lift keel along Esse 850 concept?

Good question! Probably 25-26'. Sure, like an Esse in size and a lift keel that is easy to use with a mechanism that doesn't get in the way. The idea for me is to get the price down, have good upwind capbaility with limited crew, and be able to keep at a dock with limited draft needs.

It's a boat I've never been able to make my mind uo about, it looks like so much fun and there are many people who come in really happy from a sail. In that respect there's not a lot that can beat it.

 

There are too many incarnations for proper one-design racing but they'd be great if a small fleet started and stayed on the same page, they appear to have been well sought after as 2nd hand boats, so that's good.

 

Mixed fleet though they don't appear to have the attraction in some ways of (often cheaper) downwind sleds in the sportsboat fleet. For yacht sailing (where many of them end up) there's the issue that you're sharing a course with much, much bigger boats. There was a JS9000 used to sail in our area and it was absolutely dwarved. Very hard to get clear air and quite possibly terrifying in terms of collisions against boats that could go through you without stopping, can't see you very well up close and tend to race long legs sometimes where you're more exposed to bigger waves.
