* What happens if the total hull lenght is less than 960mm ? Actually permitted, but certainly not very interesting for performances?

* I think with the proposed gauge, a boat can be designed with a hull max draft of more than 60mm maybe...

I designed both boats, Velox with Lester's excel sheet... This boat was built in the USA, it is not my building, nor my pics...

Vermine is a all by myself "dining room" built boat... I failed the fin, which is a little twisted, so I must make a new fin before really testing the boat...

expanded polystyren is I think foam material, so forbidden...
I used the planking method on foam form... but or I melted the foam, or it was covered with plastic wrapping ribbon, so "demoulded" easily after planking..
