Plasticard from model shops, can make the boat float and ballast down with plasticine. Draw it in delft ship and it will give you the panels etc

You can use the diab strip planking method. I am using this on a yacht build and it works off a basic male mould.

Any boat that can be built from sheet ply can be built from foam sandwich without a mould, just some rudimentary jigs.
A phantom for instance could be built without a mould in foam sandwich. You’d want to use thin core like 5mm else it would be too stiff, and you may want to use foam only laminated on one side for the complex curved areas.
Farr 3.7 prob too. So you could have anything with that single chine architecture for minimal investment. Still needs a lot of skill and time tho.

I'd forgotten this stuff! For years as a kid I'd make toy sailing boats from it, if I wanted something lighter than carving balsa wood. It's still available, then? You could get different thicknesses, too.

I went to a good model shop. But sure the net has some. The design above was a light weight car top touring boat with oars. Hence stern design, did have a sail also. Eventually ended up a Canoe which was modelled the same way and built.

I'm minded that making models boats is a bit Doug Lord isn't it?

However I have fashioned a couple of paper proof of concept 'things', which I'm not sure even admitting to is cool.

It led to a boat that was made, there are many other characteristics that make you Doug Lord other than modelling
