I just bought a 30 ft sailboat this winter ,I`m new to sailing and its on land until spring.its a 1981 hunter, My first question is why don`t sailboats have swim platforms like power boats do ? If I were to install a custom teak platform that would fold up out of the water and making it so its no wider than the rear of the boat,will it perform the way it should while undersail ? would it change in how the boat sails? Will it hurt anything ? I`m a scubadiver and a swim platform for getting in and out would be great on my boat. How big of rib inflatable can be pulled behide while undersail ? I have a 14ft ribbed inflatable with a 25hp motor . Is that to big of a inflatable to pull behide my 30ft while sailing? if so why? Thanks so much,
