My 909 has had a soft bottom since I purchased 3 years ago. Recently I saw another scot with a soft bottom that the owner fixed by placing a 2x6 across the inside seating area width and screwed down to the centerboard trunk. Additionally he screwed from under the seats through the 2x6. He swears that it has made the bottom stiffer and prevented the centerboard from moving. Has anyone ever heard of this being done? He told me Flying Scot approved this and it is legal to sail in competition?
