Allô!!
Thanks for your comments!! Actually, I only glue the planks on the frames. I never pegged them, I like to let the boards shine by their natural beauty without the pegs heads interfering, that's wy I enlarged the frames, I want a good contact spot. I started fairing the frames last night, which is the most important step in a nice Hull, but I HATE doing that.....I might put balsa in the nose of the boat, you're right, it helps a lot. If you have time, go in the Forum on "help with models", I posted a trick I do with Rudders.
My post is : the lucky charm rudder... talk to you soon.
