I got this outside of Seattle. I believe it is a Nacra 18 square, but the person that sold it said it is a Coyote. Anyone heard of a Coyote? I need to get a new main sail, the one that came with it is boomless with a long aluminum clew. The sail has a 18 squared printed on it. It is 12' wide and 18'LOA with a 32' mast. It does have some Nacra parts. In a pic of a Nacra 5.5sl the main I have looks the same.

18 square is an open mfr class- box rule. Coyote is one mfr but I have never seen one live.

The 18 Square pages are here:
http://www.geocities.com/mec_coleman/18square.htm

IIRC he's got a hullplan drawing of a Coyote Square posted up.

Congratulations, whatever Square it is, you'll love it. BTW the price for the mainsail at eBay is already too high. That sail is a rather old Dacron main. You'd be better served to put that money towards having a new main built, especially for as nice a boat as the picture appears to be. I recommend Glaser quite highly for Square mains. If your boat is boomless, and I see the curved traveller there, you will need to have a built main to get it right.

Husband has an extra main for a 31' stick curved traveller but his boat does have a boom. We can talk about selling it but I think you'd really be happier contacting Jay Glaser and having something made that would be right for your boat.

Yours in Squaredom

Should I consider re-rigging for a boom or stick with the boomless setup?

Back in the day most of the Cat 1 boats had deck sweeping sails (end plate theory) with radial travelers. They where very quick upwind and held their shape well downwind.
I have some shots that I will scan and post tomorrow.
PS. I'm sure that the Coyote had a flatter deck then the boat shown above. There where some guys from Canada that made some boats that had an elliptical hull shape.

I'd just hate to see holes drilled into the stick or front crossbeam just to hang a boom so you can hang an old used sail, but that's just me. YMMV.

I...guess... you could just hang any old sail whether or not its set up for boomless just to get used to the boat...um... maybe.

But it's not a matter of just adding a boom. You have to consider the relationship between the clew and the traveller or you'll end up with a hopelessly misshapen sail.

Some Square masts are 31' and some are 30'. The stock NACRA Squares had 30' masts and some folks (like me) added a foot to the stick. The sail in the eBay pic looks like a rather old stock NACRA Sq main which likely will be 30'. edit: you say the mast is 32'??

My advice is. Seriously. Absolutely. Get a sail made for THAT boat. Just as she is. Don't make changes before you've seen her performance as she was before you got hold of her.

Is this boat Virl Eichmann's?

lesburn I think you're referring to the Climax which after returning to Mike's Square Pages I discovered that the Climax Square (not the Coyote, sorry.) drawings are up at the website. Click on 'photos' the Climax drawings are there.

It may be a perspective thing but the picture here (trailered) looks like the bows are not plumb, but angled?

I got it outside of Seattle from a retired shipwright. He made some modifications. The hull connection to the beams has been modified so that each hull is 5 degrees out from being plumb. Not sure if this is a good or bad idea. I can't read the drawing to determine if the hulls are Nacra or Climax.

Tami, you should load your Square and come on down to GYC. Stack it on the F boat. You can be here by Wednesday, there's a great big concrete ramp barely a block from the club.

Hell, they'll prolly let you sail the Fboat if you want.

I will take pictures of it rigged in a day or so with the old sail. It has a clew traveler, believe it is a Skip Elliot sail. I could make some shims to get straight.

are there numbers in the f/glass of the right rear hull?

the codes there should tell you if it is a nacra or not

the solid glass hulls on my 1982 nacra are numbered

TRRC2158M82B

i believe the "TRRC" code is manufacturer and boat type?
"2158" is the production number, usually sail number too
and of the last bits "M82B" 82 means 1982, M and B could be a month code???

if the boat was made after 84/85 nacra had moved to foam/
laminate hulls. a typical nacra 5.2 of that time had a number like
NACR3002J586

where NACR is the maker, 3002 is the hull/sail? number, J5 could be boat type??? and 86 was 1986

Keepupboardfast, you had a question about the boom-less rig.
In the early 80s most of the homebuilt and custom 18Sq had boom-less sails. The theory for the deck sweeping sails came out of the C=Class cats. I will probably go boom-less on the A-Cat I am building just to get it in the water. Then see how good (or bad) the sail shape is, and how controllable it is.

The picture below is one of Bob Bergstedt's 18Sq from that time frame.

Boomless works well and would be a good choice on such a powerful one man boat. It means the mast is largely self setting once you have learned how to set the in-haul. Tension for mast rotation is created by mainsheet tension combined with the in-haul setting.
This means you have an over-rotator set-up. All the tech is well used in nacra square boats..factory often knows best.

My NACRA Square boat has a boom. Came from the factory that way.

Sheet tension against my boom, boom pushes the mast to rotate, so all I have to have is a rotation limiter.

Note that with a boom, I do not have a big triangular bit at the front of the mast which also is known as a rotation INDUCER or over-rotator.

1980s and early 90s NACRA Squares carried a boom, later NACRA Squares were boomless, custom and other builds vary. Box rule and all that.

I suppose that iwas my point. With the boomless the mast rotates automatically..you do not have to adjust the Rotation limiter. So the mast itself is not set...it resets as you lessen or tighten the main.
I found that very useful once the preset of the inhaul is understood for given wind conditions.
The over rotation device is no more complicated than the one many boomed boats use and the advantage of the spanner facing forward is obvious for mast stepping.

However, I did not understand the Nacra 18 was born with a boom. So, factory knows best. Also. using the main to set the mast can require monkey like strength.
