So design the craft around a windsurfer mast then Like the Aero then from what I've heard ?

The UFO was specifically designed to use a windsurfer mast and the Dave Clark copied the Herreshoff wishbone boom to add stiffness and control. If there has been a great development in recent years it is the modern interpretation of that rig. Details of the rig at the bottom with a picture of the Herreshoff original |

How about a scaled up low rider moth (12’ ish), late Axeman or similar, to take 80 to 90kg, able to be made from ply sheets, no standing rigging but using a windsurf mast dropped into a socket, with a sleeved sail.

Because it's a large financial outlay for something that could go out of fashion or become obsolete at any time.

Dinghies all have vastly more righting moment and thus side force thus bending / compressive load thana windsurf application. Only way to make a windsurf mast worked would be in a stayed application with a lot of spreaders like an old ior yacht, which would be more expensive than having the right tube in he first place. Cirrus is right Aero masts are produced in an italian factory which makes windsuf masts for oems, but the aero mast will be 4 to 5kg I think, whereas equivalent windsurf mast is ~2kg maybe, as the aero application is a cantilever with lots of RM compared to a windsurfer. It is on a cylindrical mandrel though, and the factory in question will be efficient at producing tubes of that sort of length in large volumes on cylindrical mandrels.

The development of the OK kit boats is an interesting twist that makes home built a bit more workable for the average modern person and I'm sure the method could be applied to other designs, new or existing. The main plus point is that there is almost zero wood cutting to be done. You send the CNC files to a laser cutting shop and they do the millimeter accurate cutting of all the ply panels and the jig to build it in. It then all comes together as a flat pack, building the accurate jig first and then the boat inside it. No messy stitch and glue - just epoxy fillets that most people can handle. Dan Leech who did the OK kit reckons about 60hours build time for the average person and you get a boat as fast as any other in the world and painted no-one would know it's not plastic.

I would certainly agree that there's more home building, conversion and repair going on down here in Aus than there is in the UK. It's not exactly like the '60's plywood home build dinghy boom, but people are significantly more confident to tackle things for some reason.

The OK can do this because it has, sensibly, a relatively heavy weight compared to some original kit boats that are impossible to build from wood to weight by the average Joe. To further make a wooden boat less likely the once kit boats are now made in foam sandwich all baked in ovens. Obviously it market driven but a shame.

Before lockdown I had seen maybe 3 paddleboards down at my lake, now there are loads of them, the lake appears to have become the local lido! They are all getting paddleboards out of their boots and pumping them up in the car park. We have now had to close membership to paddleboarders as we have too many. So the next big dinghy innovation will probably be something inflatable like this:

Wow, people will buy these and be lost to sailing. Look at the mast bend in the third photo
