Aluminium extrusions are not very suitable for unstayed masts since they have no taper. Also they are unobtainium in some parts of the world. Try...
OK, turns out Grok AI also advises internal bracing like bulkheads and carbon foam panels for the sides. So now the mast construction looks like...

>a solid laminate is better< By solid laminate do you mean no foam or a single density foam core? To give some more information on the intended...
Following your reasoning there would be no explanation for the wildly different foam densities that exist ranging from 30 to 300 kg/m2. I can see...
I was pondering this for a while and finally tried to find any information on this. I could not find much which means this is either a stupid idea...
Thanks for the heads up, I wasn't aware of this. Did some quick reading on this and there doesn't seem to be complete consensus. There is...
The cross beam is very high above the water so the forces on the attachment points would be huge due to lever effect. On the ama is getting...
My bad, I stand corrected. An actual bow rudder on a kayak would indeed be quite stupid.
I am working on a center cockpit trimaran design with a sugar scoop back and a dinghy garage under the deck. So nothing can block the stern. All...
I noticed that the Omer sail seems to have a rather big gap where the double sail meets at the trailing edge. That may create a significant amount...
For reasons of budget, availability and simplicity I am going for unstayed free standing masts. Also I like the fact there are no shrouds. Less...
