Basalt fiber is interesting, but it's also hard to find, and has only marginally higher properties than e-glass, while having lower properties...
I searched GrabCAD and Thingiverse for you and didn't find anything. I'd imagine J boats keeps a pretty tight wrap on any linesplans for obvious...
I bought a copy of "The Aero-hydrodynamics of Sailing" by C. A. Marchaj, which is often quoted when reading about sail theory. It's a massive tome...
To the original question, the elegance of an e-bike is that it still feels basically like a regular bike, has relatively the same footprint and...
The melges M16 scow has had dual bilgeboards for....well, a lot longer than I've been alive. Those angle out away from the hull so they're more...
Can't comment on the engineering, but as far as fabrication, it wouldn't be too complex to first mold the U-shape boom, then add an inner layer to...
Kevlar also has low compression strength so unless you use it in just the right place, it's not that great. Though it is low density. I would...
bajansailor- thanks for those links about Grain de Sail. I was always baffled by the SailCargo project; as cool as it is I don't understand why...
For example, I like the designs of Roberto Barras (Roberto Barros Yacht Design - List of plan http://www.yachtdesign.com.br/ingles/projetos.php),...
jehardiman- I understand that aluminum may not be better for a given SOR; I'm coming at it from a fabrication standpoint. I've done a ton of...
So I understand 3/16" or 5mm aluminum plate is approximately the practical lower limit for welding aluminum (if you don't TIG it), so with that in...
Reiterating the earlier comment about using contract SLS nylon printing, if you're going to try it. I mostly use Xometry. Many times stronger than...
I want to see this technique in R2AK. Easier on the lower back than rowing, I bet. And for a engineless sailboat, easy to look forward and hold...
CT249- yes! Sistership to the Sonata. That's where I'm leaning. Using a heavy steel plate as an end plate, which would increase draft by an inch...
