Lateen sail boat

[aeronca52]

Looking for a little help in my dreaming. In the past I have built a 16' Folbot Kayat and a 25' Bolger bateau. Also I have rebuilt a rowboat which had the flat bottom rotted out from a winter sitting on mud.
Basically all plywood/chine/nail construction.

Anyhow I am in possession of 2 lateen sails, one from a Snark and a bigger one from another Folbot called (I think) the Sport. The boat is foldable, and seats 2-3 depending how cozy you want to get.

My request is any help to find boat plans which could utilise the lateen sails. (and their included aluminum parts.) My 12 year old grandaughter wants to go sailing, she's tired of rowing. Doesn't have to be fast, once we are 30 feet from the dock we are where we want to be. Also, the previously mentioned plywood/chine/nail construction is preferred, and not much over 16'-18' long. Monohull is fine, cats are too wet for my taste but a small tri with two cockpits in tandem would be fine.

A lot of designs encourage tall rigs, that's fine,'cause that's where the air is. But I need to $tick with what I have for variou$ rea$ons.And those same reasons are why I do not want to spend $100 for a set of plans. I understand most are worth it, I just don't have those resources. Cheap is good, free is better. Have I whined enough yet? I scrounge a lot so this might take a year or two to complete.

If anybody has any thoughts or information they would like to share I would really appreciate the effort.

Thanks for reading this far.

I think your sails can be adapted to many designs. Find one with two masts and similar sail area, season to taste. You'll have to calculate the centers of area, and would be wise to leave some room for adjustment.

Thank you for the advise , John. I don't do a lot of sailing and it is helpful to know the lateen sails will work okay.

Having re-read my OP I may not have made it clear I would only use one sail on the boat, but have two different sizes for experimenting. Sorry if that wasn't clear.

Bolger's Pirate Racer design from _Boats with an Open Mind_ might be about right.
It was designed with a lateen rig.

Yes, Bolger's Pirate Racer, June Bug, Surf (or even a Teal or Elegant Punt if she wanted a smaller boat of her own) . . . all of these could be easily adapted to take your rigs. And, they are simple nail and glue plywood designs that have free (albeit small) plans available in Harold Payson's "Instant Boat" series of books.
Other options would be one of the many small, simple designs by Jim Michalak.

Don't wait a year or two to complete it!!! In a year or two she'll have developed many other interests! And you'll have lost a perfect opportunity, at a perfect age, to show her a skill she can enjoy for the rest of her life.
The boats I've named can all be built in a couple of weeks - or much quicker - and for not much money. These aren't museum pieces - they are meant to be thrown together and then enjoyed through much usage, rather than by enjoying months or years of boatbuilding. Get to it, and you can take her sailing before school starts again!

Gentry is absolutely right. Something like a Teal coud use that rig very easily. And I have built a Teal from start to finish, except for the painting, in a grand total of 4-1/2 hours. It's not a complex project at all, and it's absolutely perfect for a first boat for a 12 year old to have for her very own.

Buddy of mine has a $200 sailboat with a Lateen rig, sails right nicely. I just bought a couple of sails...one for a KatYak and one for a KatYak II...both are Lateens. One is 74 sf and the other is 55 sf. I'll get around to building boats for them sometime in the future. I might stick one on my daughters 10 ft Eiderduck so I can get my mast and sail back for my other boats.

[aeronca52]

Thanks for the encouragement, folks! For some reason, at my age, the grey matter doesn't make obvious connections as rapidly as it used to. So while out in the barn the other day I realized I might be able to make a sailboat out of the Cayat using the equipment from the other Folbot. The mast would be no sweat, and the removable leeboards and their screw on fittings look fitable (is that a word?) but I'm slowed by mounting a rudder on the stern, as the boat is double ended.

Picture me standing there with a few pieces of 1 1/2" angle iron, nuts, bolts, and questions marks floating over my head. Time to put the Google button to work. So I found this rear port quarter view of another Cayat.

Look close and see some sort of casting for the rudder to mount on. I'll have to make something workable, might take a few more head scratching minutes.

I think my Grandaughter would like the Cayat as a sailboat as she is already familiar with it as a rowboat. And the money saved from not building another boat can go towards ice cream!

Am I on the right track??

[johngsandusky]

Can be. Are you thinking of outriggers for stability? Or more like a sailing canoe? In either case, you might look at the Yahoo Canoe Sailing Forum, there are plenty of rigs there to look at.

[aeronca52]

I had given passing thought to outriggers, but since Folbot thought the boat was stable to sail without them then I wouldn't need them either. Or is that thinking a fallacy?

I can't stop thinking of outriggers as draggy contraptions willing to trip the boat over on her nose as they plow into the next wave.

[johngsandusky]

I agree with you and don't use outriggers on my sailing canoe. I do use a little ballast (two gallons). My canoe was not designed to sail, and is only 28" wide. I sail her carefully, and learned in warm shallow water, starting in light breezes. I recommend the same for anyone learning a small boat.

[aeronca52]

Agreed. I would rather just let more of the mainsheet out and go a little slower than keep it tight and tip over.

[Todd Bradshaw]

Lateens generally work quite well on small boats, but they do have one quirk that you'll want to be aware of when sailing a narrow hull with a lateen. You are much more likely to get knocked over - not because you didn't let the mainsheet out, but because you couldn't let the mainsheet out. This has to do with that long boom and your heel angle. Once the boat is heeling over to a certain point and you ease the sheet, the tail of the boom and the sail's clew corner will actually start skipping over the surface of the water. No matter how much more you ease the sheet, the sail isn't going to go out any farther. If you can't hang out to windward enough to counter the wind pressure on the sail (or bring the boat back more upright) it will gently roll over to leeward.

To prevent this, you want to be aware of your abiity to quickly put weight to windward (whatever it might be) and if that is limited due to the boat's size or your sailing position, you want to ease the sheet early and make a fairly serious effort to keep the boat sailing pretty flat most of the time. Nothing to fear, but something to keep in mind.

dare I suggest a Puddleduck Racer?

not the prettiest boat, but definitely easy to build for short money, and those who have them seem to enjoy them quite a bit (I don't own one).

[aeronca52]

Thanks for that thought, Todd. I didn't think of that and even if I did I wouldn't have given it much credence. But your statement makes me think it is a factor to reckon with.

Smithb9, I have seen PD's but at 60 some years old and 6 ft and 230 lbs I don't move too fast anymore. I need to look more like Cleopatra eating grapes on a barge. :^)

have you seen this? canoe with outriggers - could build two of the six hours canoes and experiment for ever. add dagger boards, mess about with where to step the mast to get the best balance. could be heaps of fun.

If the 'cut and paste' works, here is what I had n mind.( I'm softening up to the outrigger idea, but it still seems like hauling 2x as much gear to the water) Anyhow hope this works...http://www.dngoodchild.com/divide_for_small_craft.htm



Popularity and ease of construction have made the kayak a favorite with men and women who like to construct their own boats. This 16’ sailing kayak with lateen rig is one of the fastest boats on water, yet it is a safe sailer. It carries 90 square feet of sail.

OK, the cut and paste wasn't spot on but it did go to the site. I did manage to drag the picture and short description to here.
