Geico/boatUS no longer insures catamarans. Absolutely absurd that they are lumping every single sail multihull into the same bucket. A hobie cat is no...

Can you tell me more about the design? I know you said it is a kelsall 34, but I can't find anything that looks similar with a google search.

poor bees, just looking for somewhere to go, but instead they get dunked in the water

The rudders look usable as is, no? and the one centerboard may be good enough to take a mold of off, or at least copy measurements to make out of wood

The route for the miami-key largo race brings you under the Jewfish Creek bridge, which is the first opportunity to get the bayside. It can be difficu...

is that a 6.0?

What about laminating a tang onto the boat instead of cutting it open?

what material?

Dacron or nylon would be easy enough. I have a book, "Sails", that goes over (rather outdated) methods of construction. There are rules of thumb you c...

The lower the better. less moment arm for the top to bend over. (done that)

even better, i could make them out of carbon. How much are the australians/euros asking for the aluminum ones?

You've got it backwards, it is supposed to be "the whole is more than the sum of its parts"

I have the feeling that whoever owns this boat has no idea how to sail it, judging by that absurd picture of the mainsheet, the batten tension, and ru...

I haven't actually made anything with it yet, but sailcad has some pretty neat graphics.

what parts?

heating aluminum will usually make it more brittle, not more ductile.

If by 6 oz mat you mean chopped strand mat, absolutely do not use that. Pick up some unidirectional glass, and use that for the long axis, and then so...

Have you calculated how much skin you will need to get the foam neutrally buoyant? And remember, if you use carbon, any glass becomes more or less str...

I got 2000 lbs, assuming that all of the sail force is transmitted to the board, and finding that force using a pressure chart and the known sail area...

I did a box approximation, and got 60oz per side (.094 inches) which is surprisingly close to samc99us answer. I then tried to simulate it with FEA so...

That seems like an excellent deal

Are you talking about weather helm? Make sure the rudders are locked in the full, upright position, with drink trays stowed.

Is it true that a dull finish is faster (in the water) than a glossy one? (besides being faster to prep and apply)

God, who came up with that. More weight, more wetted area, and the same righting moment

The whole boat needs to be done. See the splotchy color on the bow nearer the camera? That's not a shadow, its a paint or filler or something. And wh...

I've sprayed gelcoat over a whole hull before and I have absolutely no desire to do it again. I think the reason the deck is like that was for a dagge...
