Oh Pooh-bah, perhaps knowing they are as am I that i550 boats are very breaking easy to me. The keel is so small and light I can carry easily to the boss man but only receive a small roti it for.  

Sahib, I know not how to read or write but I do know how to break boats. I also a little know how to sail from those boats with the training wheels. I would be glad to come to the land of the Solomo

I am searching for a source of sustainably harvested plywood made to the BS 1088 specification. Also if anyone has experience with the bio-derived epoxy offerings, let me know your experience.  T

What a great weekend of OD i550 racing!!

 

Olympia was a blast and we got some ideal conditions followed by some big breeze conditions on Sunday.

 

Seems that the boat is a touch faster than a Star (they were the fleet starting 5 minutes ahead of us) in anything over 12 knots.

 

Should have a BUNCH of photos from the support and RC boats coming soon!

 

Here is a little pre-race shot...

I've been in (T)acoma early Spring water. What, it musta been in the low 50's?? Who was the unidentified diver in mid dive in the photo. One lost nut probably had the swimmer thinking he had two nyloks himself.

 

Great news about the fun you guys had. What's the next stop on the i550 NW road trip regatta extravaganza?

 

There is an i550 with Carbon rig for sale in the SA Classifieds.

Apparently the "nut" disappeared somewhere along I-5. Boat went in the water, keel went down, boat got moved away from the ramp. Owner stepped on the boat and a grinding noise, followed by a slurping noise, followed by a THUMP, then ensued. The keel eye bolt and end plate were all that remained in the boat and the keel was in about 12 - 15 feet of water at low tide. No problem... fish a line down the centerboard trunk, dive into the water, loop line through top of foil, drop second line through centerboard trunk, fish that out with a paddle, tie lines together, then pull... pull... pull... rotate board to fit through trunk and pull... pull... pull... oh wait! Its backwards! Lower, rotate, pull... pull... pull... Install top plate and Nylock this time, finish rigging boat, haul ass out to the race course and then win the regatta... good job #250!!

That dark blue and green one is farkin' gorgeous, amazing

Yes, yes it is! If you haven't seen it in person, the pictures are just the start.

 

Stephen built the i550 as his high school senior project and he completed it in seven months. If you only have seen the Black Star Regatta photos, take a look at his blogs and the news paper article.

John D,

For the past 3 years Wild Child (i550 #172) has been racing just 55 miles north of you in Merritt Island. He has an aluminum rig, so approximately 30-40 lbs. Totalxs is up in Jacksonville FL and Im out of Columbia, SC. I've purchased a used aluminum Viper rig that is heavier. The boat is not finished and Im more than 175 lbs, but I do not foresee problems raising the rig. PM me if you have questions. Photos from Melbourne Yacht Club website.

Congratulations on getting four boats in the water. Just remember, without pictures it did not happen. Any updates on the other Tass boats? A November Facebook post has five boats completed, a sixth boat almost done, another one purchased and three more being built. Who owns the boat pictured below and which boat was flipped in the youtube video?

Mast stepping? Single handed by a 175 lb. guy?

Easy... fully rigged we are at 28# for our masts... deck step with a Melges 24 base/hinge and you just walk it up and tighten the spinnaker halyard/jib halyard once its up.

Rigged the boat Friday by myself in about 40 minutes.

If you keel step it might be a bit harder, but still shouldn't be an issue.

does any body know if this would be a good boat for a river (noosa river) with sometimes shallow water, shifty winds and no waves.

So long as you have 4.5' of water its fine... thin, but fine. No waves is good... although the boats handled well in big breeze and waves a few weeks ago in Olympia!

Tim, the boat looks great! It is the first kit that watershed made. You've done a great job. All of the kits we've made are either done and sailing or really close to getting wet. Chad in NE Missouri has built a beauty from just the plans and is probably pacing up and down the driveway waiting for his mainsail to fall off the truck.

 

Gordo in Canberra, A.C.T. has been having fun with his i550 "tonka" with a number of good results and some podium appearances. The Portland i550 mafia has an active schedule this summer as Team Gladiator has posted earlier. Jon on Flathead Lake in Montana has a great looking boat with a Special "Flattie Attractor" appendage. There is a group in Croatia with multiple boats sailing, too.

 

We (Susan and I) are absolutely thrilled that all the hard work you builders have put in has been so pleasantly rewarded.

 

Who knows, the i550 may be an International class in a few years?

 

Regards to all,

Started cutting on mine here on Vancouver Island not long ago, #239. Viper aluminum mast , hoping to finish by next spring.

90 cm is a big difference in waterline length= speed uphill. Down wind nobody knows . . . . yet. Phrf may settle in around 140, we don't know yet.

 

We can use the Viper mast, sail area is about the same at 22 m. Some asyms might be as big as 55 m.

 

$15k vs. $35k

 

And I'm never going back to Memphis.

how does the i550 go against a shaw 650?

Gets hosed. No comparison at all. Different in every manner.

That would be my comment as well; the boats are pretty radically different.

 

what about the viper 640?

Viper 640 = Melges 24 in speed (roughly); the i550 is a fair bit slower uphill for sure, but will break loose down wind a lot earlier. We saw in conditions that would not allow the Melges 24 to plane (but the i550 was able to do so) that the i550 was faster downwind. The best "off the shelf" comparison is going to be to the Open 570; similar waterline length; similar wetted surface (the i550 has a bit less); similar weight and sail area. I'd really like to see the two boats sailed side-by-side.

 

90 cm is a big difference in waterline length= speed uphill. Down wind nobody knows . . . . yet. Phrf may settle in around 140, we don't know yet.

 

We can use the Viper mast, sail area is about the same at 22 m. Some asyms might be as big as 55 m.

You can use a Viper mast, but it is a FRACTIONAL hoist rig; if you want to maximize the sail area on the kite you will need to add some rigging. Either another set of spreaders or a set of jumpers. I am assuming that the top of the Viper rig isn't designed for the extra load of a mast head kite.

 

As for speed comparisons that we know of from side-by-side or on the same course sailing:

Star v. i550:

6-10 knots: Star is marginally faster upwind (longer waterline, points higher); i550 is slightly faster downwind, but has similar VMG on W-L courses; net same around the course time

15+: Star is about the same upwind; i550 is significantly faster downwind, with better VMG on W-L; the i550 gained about 3-5 minutes in a 30 minute race

Lightning v. i550:

6-8 knots: same upwind; faster downwind with similar VMG; net same

8 - 12: same upwind; much faster downwind; the i550 gained about 3 minutes in a 20 minute race

 

Hopefully we will have some more comparisons soon, but if you are looking at "ratings" PHRF should be the same/similar to Open570 or Star, Portsmouth should be same/similar to Lightning or Star.

But who cares about ratings?? Build a fleet and sail OD... way more enjoyable!

Team Glad, thanks for the comparative observations. The evidence of a sweet spot for the boat is growing.

Who is going to put running backstays on their boat and helmets on their heads and do the double dam up the Columbia? Portland you know ya wanna.

We got the boat out in a little more breeze this weekend, about 12-15, and got the main up as well. So a big increase in loads from the last jib only (whoops!) "float test". I found my first chink in the armor- the rudder gyber isn't quite up to the task. The centralizing line doesn't generate quite enough tension, is a little difficult to use, and worst of all it works its way out of the cleat, grrr. So my plan (before just abandoning the idea and screwing the gudgeons to the transom!) is to bump the purchase from 2:1 up to 3:1, make a new centralizer cleat holder that holds the cam cleat upside down so I can yank up and into the cleat rather than scrape my knuckles trying to pull horizontally (that was never a good idea, duh), and splice the lines together so they can't move independently in the cover as (I think) they are doing now and thus working out of the cleat. So more purchase, and better ergonomics. Then bin the idea...

...and I need to work on my main cunningham -not enough throw as it sits now, and I need to keep chipping away at the mast tune. Steps forward, steps backward, hopefully net progress, we'll see!


The boat handles 50mph crosswinds on the trailer just fine though, and the 3 hour road trip went smoothly. It makes a tidy little road package:

post-4941-0-79284300-1369778913_thumb.jpg


My second trip into the water took an hour and a half from parking lot to water, solo, so I've got some work to do there to smooth things a bit.


Last pic, trial fitting the main at home, top two battens only:

Hey, rather than a plate, I like your keel drop-stoppers. What are they fabricated out of? Having them cross-bolted (horizontal) rather than screwed into the top of the keel foil (vertical) seems like a lot more insurance against the whole deal ending up as part of a reef somewhere!

 

It does look like your outhaul on that main is close to maxxed out...is it enough to handle that foot length?

Link to post
Share on other sites

The outhaul can strap the foot just fine. One of the strings I think I got right!

 

The keel top is both a tiller and a no-drop "plate". The tiller uses the side cheeks you see to grab the head of the keel. The plate is held down/keel held up by a honking bolt embedded vertically in the keel head.

 

The gybing keel is the reason for the gybing (well, swinging) rudder, to get it out of the keel's wake as the hull rotates to align the two. See Bethwaite v.1 for a better explanation, if it interests you.

 

Obviously, I've used the boat as a vehicle to try a handful of "I wonder if" ideas, and will be perfectly happy if just a few actually "work".

That main is too big

..................gotta love the -no-limits- game!! :)

Wow. if that sq. top works you can throw away the head is 40-50% of the foot lenght theory. Maybe a little Viagra is in order.

how does the i550 go against a shaw 650?

Bit hard to compare a 5.5m with 3 crew built to a ply budget to the quickest 6.5m boat with 4 crew built to a composite budget.

 

At a guess would be something like 7-10min slower per hour? Maybe more in certain conditions?

 

650 is doing 6.2-6.7 knots upwind, and other than arms racer one off boats would be the first to plane and the quickest once up and planing. The i550 is a lovely boat and a very cool concept, but I guess if you really wanted an answer could compare the Manic vs. the open 570 in Narrangsett or Monkey Business/Audi Penfold Racing vw. the i550 death to Snooki (or some name like that) in Melbourne.

 

I'm also building a Shaw 550 (one of the first ones as a fun little boat for messing around) so would guess that would be a lot closer to i550 pace, more similar to an open 570 but should be quicker by the time I put a proper kite on it (compared to an open 570 with its hankerchief). There were a couple of i550s started here in Thailand, but nothing has happened on them in a while.

I love how you are trying all of these ideas, some will work and some won't. The photo with the main up in it, the rig doesn't have any tension on does it? Honestly i think you will be cutting that main down light air or not. we sailed the old boat with about 590lbs of crew weight with a 2'6" square top and we were powered up very well. It looks nearly to the point where it will be more the case of "Rag is Drag" compared to a big but efficient sail plan. (just my 2 cents from past experience. not trying to pop your bubble ;-)

The largest gathering of i550s in world history is about occur at Vancouver Lake Sailing Club. 5 boats from 2 countries... watch us grow at:

 

www.i550na.org

 

.....and rumblefish is out to show that a simlpebuilt with old aluminum mast from a scow,,,used sails from a melges20,,,hunky handbuilt blades,,and an unfaired bulb is 'just fine'....against the beautiful yet technical Portland boats......so far we've had 2 light-air races after a long wait,,,,the fleet's been pretty good organizationally-figuring out the starting sequence and courses through some confusion........I woke today to find rumblefish in first this morning for a 2,(2)1,,,unfortunately BrianL of the Portland fleet, went from a 1,1 to a 1,2 for an OCS :mellow: ..............all's fair in love,war,and sailboat racing though,,,,we ocs'd in the first race y'day but restarted

......things should be interesting today,,breeze is on already at 8am.....let's see how things go!.......hope none of the other guys reads SA this morning!! :rolleyes:

 

....a wild thing about this multifleet event is that the RC starts random fleets together--- we started with Lido14's in first race,,,thistles in the 2nd-----whodathunk that thistle's would boatspeed i550's in ~2knots of breeze!!! :unsure:

 

...kudos to Vancouver Lake Sailing Club for their great hospitality,,,a fine oldschool campout with bonfire,,,coffee on at 6,,,and sausage/pancakes at shortly after....what a team!!

 

 

...................GO THE RUMBLEFISH!!! :rolleyes::rolleyes:

can someone tell me, the fastest recorded sailing with I550

 

 

Close to 21knots top speed. 10second average speed recorded was like 20.5 for memory. Doubt any of the others have gone that fast.

 

...errr,sorry Tokyo,,,just got off from doing 55mph,,,,had to stop for gas! :rolleyes:

 

......today's racing was fun,,,breezes generally in the 12-16 range,,,,good close racing all-round...

...BrianL got his ocs reinstated,,,went on to win the event,,,with the mighty Rumblefish getting 2nd....YAY cobbled-together boats!!

 

......I believe all would agree that upwind,,,in low to moderate winds at least ,,it don't really matter what you've got i550-wise,,,,wether it's cobbled or engineered whether it's 2 knots or 15,,,2 or 3 sailors,,flat roucker or round,,,,,upwind ,it don't really matter what you've brought,,,the boats are virtually the same speed ,,,gains/losses are more through windshifts :mellow:

 

...downwind in the fleet so far,,,'handling' issues are the key

 

...looking forward to a seaatle event in 3 weeks........couch-OUT!!!

You forgot to mention that next weekend the NW group is holding their 4th Regatta of 2013 in Seattle (Shilshole 6/21-6/23). Contact Team Gladiator on SA, or Eric on the i550NA.org site for possible demo opportunities Friday evening.

 

Team Gladiator,

Your link to the Olympic photos is broken, however I found another link to Thera Black photos from the Black Star Regatta – i550 event. https://picasaweb.google.com/109979027216186864891/I550MeetApril2013# I personally like the photo of i550-410 rounding a mark. She did a great job taking these photos, so remember they are copyrighted.

Thanks Jon for the reminder. Nick Stahl had sent out an announcement about Shilshole, I also mentioned it on Pressure Drop, Sailing X & the Yahoo group. Hope to use the i550 Yahoo Group more as many more have signed up.

Hi Viz looks like a good bit of kit, Matt & his students have done a great job, When it warms up down here a few of us will fight over the next ride.

Congratulations on getting four boats in the water. Just remember, without pictures it did not happen. Any updates on the other Tass boats? A November Facebook post has five boats completed, a sixth boat almost done, another one purchased and three more being built. Who owns the boat pictured below and which boat was flipped in the youtube video?

The orange boat is Hi Viz built by teacher Matt Westland and his team of students at Claremont College. It was commissioned by the Bellerive Yacht Club as a training boat.
That is freaking awesome! How has the response been from the membership at Bellerive YC training on it? Are more boats being built?

As loong as everyone is asking about speed and this boat vs that boat, I know they are not the same style, or class, but 18' boats being 18' boats, how will the i550 compare to mass produced boats like precision 18, hunter 18, catalina 18

They are in different worlds. The i550 wants to plane and does. The others might, on a extremely rare unusual day and scare the s*** out of the family.

 

The weight, sail area and shape of the boats dictate that they are in different worlds.

For the production boats, weight about 100-200 more, definitely lacking in sail area, shape of the boats??? My experience with the Hunter 18, is a broad flat bottom with rounded chines. More wetted surface, but I thought that the bottom shape would help it surf better??? No? Is the difference because the bottom of the i550 is so narrow, compared?

the real truth is that I don't know the physics. But somewhere there is that sweet spot when enough energy is generated by the sails it overcomes the friction of water on the hull, or is it hull on water?

Greater wetted surface has more friction. Smaller sails= less energy. Some French guy named Freund or Freud (not the shrink) about 200 years ago played around with models and came up with numbers.

 

Or I could be very wrong.

 

Somebody help me.....
