Would this qualify as "tortured ply": http://tinyurl.com/c3cw49n

On my windsurfing sails, the mast is bent by tension on the sail panel that runs parallel to the mast. Downhaul gets applied to that panel. The rest of the sail is shaped, but not under any...

I like the crab claw. Does anybody know what he used for spars and whether they are pre-bent or bent by virtue of the sale's shape?

In retrospect, it sounds like that was the right thing to do with the rack brackets.

For the leeboard bracket and the seat slats, I don't want them to contrast with the rest of the canoe (which is...

I made a couple of crude brackets to stabilize my surf ski on the roof racks.

Didn't bother to coat them, and the weather was having it's way.

So I figured I'd thin some epoxy resin by adding...

Easy set/strike was the litmus test for me.

Going under bridges/causeways was my original thinking, but it turns out I have yet to go under a bridge or causeway... -)

I have not done that, but I do have the rigging time for my Ulua outrigger canoe (from trailer in parking lot to water's edge ready to sail) down to a "personal best" of 19 minutes and 38 seconds.

What would be an example of "flexible"? "Rigid"?

Some of it has to be hull shape.

OTOH, my Malibu Outrigger tended to pound more (OTOH, it would also sort...

Consider an old windsurfer mast: cheap and light (especially if you can find one in carbon fiber).

Part of it has to be exposure of the tramp to wind. Dunno how much... but somebody less mathmatically-challenged than Yours Truly could probably calculate how much the area exposed to wind increases...

Good catch. I'll take it - only expanding "beach sailing" to "beach and back-bay sailing".

I guess there's ocean/blue-water sailing and then there's everything else.

My vision of sailing a "sports" proa has been pretty much Grillabong's setup where he uses something very like a beach chair on the polas so the helmsman can sit in one place if desired. viz:...

The plates on both sides would only go down as far as the water line, right?

I had been puzzling over how/why the Marshallese ama suspension as shown in http://www.instructables.com/id/Aka/?ALLSTEPS works.

Now, just having had a look at one of Janusz Ostrowski's clips at...

Dunno from guidlines, but my experience so far with a 21' tacking outrigger suggests making the iakos longer that I would ever want and then tuning the rig by sliding them in and out to see what...

Is anybody on the East Coast USA sailing Waapa with a shunting rig?

I did and bought one.

Does everything I need done.

Thanks.

That's what I did when concept-testing the idea. Took it out the local lake, swamped it, loosened the herc straps holding the iakos in place, slid the iakos in till it looked right, and then righted...

Seems like disconnecting would defeat the functionality of using that ama as floatation to raise the vaka out of the water while righting - so that the water inside gets dumped.

The idea being to...

I wonder how far out the safety ama has to be to do it's job.

If I ever try fooling around with one, I think I will start with it very close to the vaka - maybe just enough room to paddle.

Then...

I use a steering paddle on trimaran tack and a steering oar on proa tack.

Another option would be to load whatever gear is being carried out over the ama, but I don't carry much gear.

Now...

I'm trying to figure out what he's using for the broken wing ama.

Maybe an old-but-very-skinny SUP turned upside-down?

Assuming I want to screw this seat in place instead of gluing it (against the day when I need to move it), can anybody suggest a number of screws?

When I did the test fit it became clear that the...

Sounds like that might also work for sailing if one is willing to hike out on the non-ama side.

Yes.

I still cannot paddle Ulua reliably without using a rudder. Seems like once the bow deviates a certain amount from course, it's all over and no amount of corrective stroke will save it until...
