The real problem with the seaclipper or searunner idea is the rounded off edge of the ply.
That looks really bad when finished bright - It was just a really bad suggestion on my part.

Forgot about the bright finish. Since I've decided to never do that again.

Thanks for pointing that out. :mad:

Depending on the radius of the chine that you want you might use the technique that Searunners have used for 40 - 50 years.

If you use a chainsaw mill to make boards from logs, be sure to get a "ripping" chain. Don't use the normal cross cutting chain.

3/16 has been used for a standard design.
I found them very hard to keep fair, once that happened, there was not enough thickness for sanding to get fair. so I had to fill. Then I had to paint...

Wizbang is right, Texas needs more wooden boats.

Any progress?

Listen to Wiz, and Todd.

Additionally you really don't want to epoxy glue between the layers.
Think about the process required and the waste in epoxy when you have to take more time for a strip...

Wood is biodegradable.
Cheap plywood is even more biodegradable.

What do you want for a Boat?

A few years?

Part of the problem is that cheap plywood often has voids, which severely affect...

OH NO! I didn't phrase the last comment well. What I meant to say is that the board cannot be too far back from the sail CE.

The sail and board need to be close.
The rudder is plenty far back to...

If you put the leeboard (any board) CE too close to the rudder, you won't be able to get it to go upwind. Too much turning moment between the sail CE and the centerboard and the rudder won't have...

Lee, I'd listen to anything Todd says. And I always do.
The Farrier 20 looks good, I don't know anything about the mast size / section shape to see if it would match well with the Hobie 16 mast.

Looked at your "hobie" with square top.
It gives me the creeps.
I think your square top has little relationship to the original Hobie sail plan. The Hobie has a noticeably long boom. If you do this...

The issue of stepping a mast as if it is unsupported by shrouds is exactly why a freestanding mast is mostly impractical for trailer boats, IMHO.
Cats which use a hinge at the base of the mast are...

Lee your attachment for the hobie rig on your boat did not work.

By the way, the latest hobie masts are aluminum, with an upper section of carbon fiber (I'm not sure its fiberglass instead of...

Lee,

A Hobie 16 mast is 26'. Last time I dealt with one I was 65 yo. It was so easy I can't understand what you are concerned with. That was just connecting the base to the boat and walking it up...

Where are you going to attach the shrouds?

Eliminate the backstay.
Move the mast back, shrouds go to a bridle to the ends of the ama's
Put the 51 sq ft into the main, with additional height on...

What's that in real terms? :d

Lee,

A 23' mast should be simple to trailer.
you need a support at the front of the trailer which is fairly tall, that puts the mast over the top of the truck.
Hobies did this with a 26' mast,...

Per my understanding, Bondo and fairing compound should not be considered the same thing.
And I wouldn't use Bondo on a boat.
Bondo is a trade name for a specific product used on cars.
IMHO -...

If you do use a kayak like method, remember the cost of the forms. It might make the two methods similar in cost. I've never tried to make a cost comparison.

I think I've said this, but I will not...

How are you planning to make the hulls?
I thought Smooth's boats were plywood designed.

Are you going to strip plank to the same hull shape?

Its pretty simple.
The belt comes out the back to the motor.
Just look at it.

The open cutout in the back allows you to get your hand in to the pulley on the blade.
I suggest you use a toggle...

You probably want to know what kind of leather also.
Actually I want to know.

I need a waterproof leather for archery.
Sorry for the thread drift but can any one help?

Sounds like something similar to wooden kayak construction, with the exception that you are also face gluing to the base plywood.
I'd use titebond, the facebond means you don't need anything...

Lee, have you asked the designer what he thinks about your proposed changes?
Are you going to increase the sail area due to the increased displacement, or are you going to just let the boat have a...

The hard surface will run smooth against the polymer bearings, heating will be reduced and the heat will be spread evenly so the epoxy...

Prepare to do the joint over again if you rub on epoxy, with anything in it.
Friction will raise the temp at the epoxy surface, the epoxy will soften , stick, and get worn quickly.

Guys, I don't want a birthday.

:D:D
Thanks anyway.

Looks nice, but its a pity you rounded the edges of the longerons.
I did that and it made a perfect place to trap debris that got inside the boat.
Eventually (not long) the debris would get between...

Lee,

I know of a Farrier 18 which has never been completed. The current owner just died, his widow needs to sell it.
Amas are complete, the Main hull is framed but not planked.
Both were done...

Three Cedars.

I did not. My boats were all Sea Tours of various sizes.

Good luck.

I built 7 Yost kayaks, none had "deck plates". But none were the greenland style.
That area has more wood than anywhere else on the boat, I have never seen any suggestion there was a problem.

Dave has always been generous with his replies to me.

Don't think too much, just do it.

Although reverse curvature is really not doable.

Good luck, Texas is not a hotbed of restoration for wood.

Congratulation on both of you surviving. Seriously.

When you have a chance to calmly think about what happened and why, you will be able to review old comments and see where there were good...

I've built 5 strip plank kayaks, and 7 skin and frame.
Never made more than materials on any of them, gave most away free.

That's in texas, not a hot spot.

Just build your boat, burn the...

Lee,

The issue of not having the transom in the water is important (Woxbox comment), but there is another way to make this happen.
Typically daysailing catamarans do not have a great deal of...

Thats a bold color scheme, glad you're trying something different.

I'm personally never going to do wood look ever again. Too easily damaged.
Or I'm too lazy, or both.

Will this have a centerboard/ daggerboard/ leeboard?
Don't count on the square edges of the hull to resist leeway.

Looks OK if you have a board of some kind, big enough.

How much volume will...

Sorry if I'm being too pushy.

Please let us know if you actually find the Cross 18 plans in that 500 plan set.
My understanding is that you might find "study plans" which would not give you...

I sent a message to Gumprect several years ago about that boat.
No response.
Good luck.

But that is not a simple quick boat.

You ought to look at the Cross 18.
One problem, no active plan...

A wet suit can't be kept dry, unless you never get in the water.
Its made to suck up water.

You need a "dry" suit to keep dry. Completely different thing and lots more expensive (or used to be).

Did you get the wet suit completely wet?
It won't keep you warm until it is soaked, and your body heat makes the water in the suit warm.
A dry wet suit is not much use.

Pity there was so little...

Stayed masts seem complex, but are really easier.
You will get use to a single piece mast quickly.

Watch out for the anti-epoxy guys - especially the Cetol ones.

It is easier to get a strong epoxy coat if you use one layer of glass to add thickness. 7 coats????? Download a copy of Gougeon...

Lee,

Perhaps you could help me understand a little more.
Are you planning on having the amas bouyancy low enough that they will submerge rather than the main hull rising out of the water?
Why do...

Dave,

You might need to work a little on details of this "thing".
I spent my professional life drawing parts and can't understand what you want.

But, you can't make carbon fiber structure...
