Is sailing for me?
As far as your wieght affecting the boat''s speed, this is not always true. In medium to high winds your weight would accually be an advantage! In light winds you could easily make up for your extra weight by sailing smart, triming sails correctlly, good tactics, and moving your weight smoothly. The boats you are speaking of do use two people to sail, and if possible pick someone that is light. Your combined weight (this is what counts, not your own weight) will then be that of anyone teams. Hope this helps!
