Shape rails, i keep flat deck. For that i mark and cut 3 main bevels then bevel the bevel again and again and final sandscreen.

Nice! Bet guys at Peahi(Jaws) would love to take that thing out. I once took a 8’6 Clark Windsurf blank and did something very similar. Thank you for the nice pics too. Good pictures make it easy to see where you’re going.

Hi Lemat,

Can you perhaps elaborate on the omega bottom stringer? Why are there still (looks like 3-4mm) gaps on the bottom?

I always had the idea it was laminated cloth like a U-profile with the opening towards the bottom and then filled with foam.

Yes you are right i still call this omega because it was what i did but now it’s more a rectangular tube where both wider side are fibers and others fiber mastic.
Here sides are filled with reinforced epoxy mastic and blank sealed
