Hello, For well know reasons , I am looking for a bilge keels Moody . As many people I am a little bit afraid about the way they are sailing upwind . I read many positive comments posted by owners stating that finally they are satisfied . But to make my final decision, are there any objective polar curves (predicted speed) available ? I am in discussions for a 35 CC or a S31 , and unfortunately the sellers are not able to provide figures and it is also impossible at this stage to get out on the sea . Thanks in advance for your help .
