Ketch: no problem, just hire a NA to design you a new rig. Electric: no problem as long as you have the skills to sail engineless around the...
Well, you do waht you must. If you use plain steel bolts, paint them with epoxy primer and paint before installing.
If it's just a liner as antifouling and a little bit of abrasion protection, why the big thickness? 1-3/32" is enough, bend by hand, weld the...
You are looking at it the wrong way. The boat was designed to have a 2200lbs keel suspended from the hull at a certain place, and that point is...
Your suspicion is wrong. It's a naturalized timber, not a native, and is all you asked for, durable, termite resistant, light, and works well with...
Golden cypress (cupressus macrocarpa) or oregon pine would be best.
It's easy to be drawn down the rabbit hole of the better mouse trap (and I am guilty of that) but you need to take a moment and look at real world...
Man, somebody really did a number on those cabin sides. Those black spots, that's not only cosmetic, it's the onset of rot. It still can be saved...
A steel long keel/skeg combination? The hull was never designed for that, if you want it just glass a piece of wood or G10 there. If you want roll...
Why do you need a keel at all? Just dump some ballast into the bilges and be done with it.
I don't know how your cabin house is constructed, so I can offer only general advice. The way to verify cabin construction material is to remove...
Any algorithm you develop (wich you can only do by testing, first in a tank then for real) is for normal operating conditions. For example you can...
The West Mekan unit will have the same "problems" as the Oceanvolt one, meaning it will keep adjusting the blades forever, consuming current and...
You designed that prop to be efficient at a certain rpm, so that's your target. You pedal at a certain preferred cadence, that's your input. The...
You would have to glue the fiberglass with thickened epoxy, and weigh or clamp the foam down while maintaining a fair surface. In my opinion if...
A golf cart will have all needed components, if you are lucky even the charger. The wiring harness will have to be adapted in lenght, so it fits...
Google videos for "sailing outrigger canoe". If you want traditional ones, the tackers were in Hawaii and Tahiti.
I understand that the original Whio was reported at 1100kg (2425lbs) with empty tanks. It's no problem to achieve that weight with cold molding on...
It's possible to do it like in your latest drawing, but it does not make sense. If you are using the house roof as one plate of the box girder you...
I'll try to explain the houseboat in land architecture terms, so it's challenges are better understood by the OP. You are building a house on a...
