      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.

Early morning Saturday prediction by Accuweather is NNW gusts to 30- apparently all day. Racing tomorrow Sunday only, eh?

Wow, looks like the weather just screwed everyone over. Only got five races off and only half the 40 boats there managed not to DNC/DNF.

Wow, looks like the weather just screwed everyone over. Only got five races off and only half the 40 boats there managed not to DNC/DNF.

 

Half the fleet DNC scores in the overall is because the regatta rules split the fleet after the three races on Saturday of which only 27 of the 46 boat fleet raced (18-22 knots with higher gusts, pretty full on racing right at the limit of class wind max). On Sunday, half the fleet raced the "Intergalactic" (three races sailed) and half continued in the "A" fleet (two races sailed). Sunday racing in very light to moderate and very shifty conditions (3-10 knots).

 

We were hoping for three days of racing in classic Galveston Bay sea breeze conditions (southeast, 12-18 knots), Mother Nature said otherwise!

 

Top Three "A" Fleet

 

1. Matt Struble

2. Bruce Mahoney

3. Allen Coutts

 

Bob Curry won the Intergalactic fleet.

Bob, congrats on a top ten finish. Even though the weather was shit, reports from my driver Matt were that everyone was extremely helpful getting him up to speed (3rd and 4th on Sunday). He learned enough during the week to make the trip worthwhile. Now we need to get the west coast fleet active again.

Why the split fleet? I was talking with another sailor about the upcoming Worlds and the split fleet format. There are definitely both positives and negatives to this format. What happened at the Nationals is something that we were discussing. It can be difficult enough to get in two good races in a day.....even harder to get in four.

The split fleet format certainly had its pros and cons and the regatta OA wanted to give it a go. On the positive side it gave the RC more practice in getting starts/races off. On the negative (if you want to call it that), most of the sailors who felt they would not make the "cut" still wanted to get on the starting line against the faster sailors.

Some of the guys at the Nationals were using or talking about using 12:1 systems. I didn't actually see one and was wondering the best way to achieve this. I believe guys were using either a 3:1 or 4:1 on the end of the boom to traveler and either a 4:1 or 3:1 along the boom to get 12:1.

 

Any ideas the best way (and what hardware) to achieve this? I'm thinking a 3:1 at the end of the boom to traveler and 4:1 along the boom? What size sheaves, etc.?

 

Today I tried a 6:1 on the boom/traveler and a 2:1 on the boom but it doesn't quite have enough throw to release the power out of the sail before the blocks run out of throw - scary. Otherwise it was really, really nice.

 

Does the 4:1 along the boom have enough throw?

 

A-man

With the 4-1 on the boom (3-1 on the traveler) you'll double the throw over your previous system.

I did a 4:1 in the back and 3:1 along the boom. There seems to be enough sheet for easing and not too much more tail to deal with, it's pretty nice on the arms.

Wow! Steve Brewin made up a 10:1 system which I later borrowed and we both concluded that it simply meant shifting too much rope for not enough benefit. I think we are both using 9:1 at the moment, with his being all at the back but thenm led along the boom to centre sheet while I go 3:1 from boom to traveller and 3:1 on the boom.

 

However, the 10:1 was a traveller mounted system so I can see it might be different going along the boom. What is achieved with the 12:1? I can see that loads might be less, but the amount of sheet needed to be moved seems excessive. Where are the reduced loads most noticed? Is it upwind or downwind?

4:1 rear using wire blocks and 4mm D12 with internal boom 30mm blocks and 8mm sheet ( they take a lot less loading than at the rear ) offers a much cheaper alternative to more normal multi block at the rear. But and a very big but, the whole setup is very temperamental if you don't get the whole set up running in line correctly. Little things like my sail loop under the boom at the rear when loaded would keep the boom slightly twisted to the line of blocks, D12 can narrow down to really impossibly small ovoid shaped diameters and would jam in the gap between the pulley and the side of the wire block when running down wind and jybing, I have no idea how but it would. solved that little dillema by putting a small tail on the boom top block with a guide pulley in the boom. But the thing that sold the cascade system to me was way it free runs without almost no drag, nice but a problem when you tack, it simply sheets out unless you lock off the sheet some how ( stand on the sheet as you come in and off the trapeze until you can get a shorter hand ful of line ).

 

Why did I go to 12:1 and not 9:1, I had what was effectively tennis elbow and it was painful to sheet in one side, no problem with 12:1 but more rope to pull. Simply do as I did though and use a double block top and bottom with becket on one and you can experiment to your hearts content. Why internal inside the boom, I kept getting tangled up with the under slung 3:1, I know some have covers but when well designed, they fit nicely inside the boom. Try a set up with old blocks you have laying about in your spares tin.

 

This has been often discussed on the cat sailor site and most Tornados went over to a cascaded system, its well documented and diagrams abound.

I guess we just use more mainsheet tension on this side of the planet...

 

Have been running 12/1 for 9 months or so. The extra line is no problem and I can close the leach in any wind strength and hold the main sheet with two fingers at any time. 4/1 external, 3/1 interal, took a while to sort out but now reliable.

Am new to the class and the boat. It would be of great help to view any of the referenced main sheet set up by photo. Much appreciated to all.

Well, I'm definitely in the tennis elbow/pussy category. 12:1 for me, I have seen the light. Thanks for the input.

Yeah, then when you are about 65, the fingers get sprained, hands get overstressed = carpal tunnel/ arthritis and aspirins/Tylenol.

Then tendonitis/ tennis elbow comes along.

Don't F$%^&*( ASK ME HOW I KNOW.
