gobbs easier
rolling on the bottom paint is a ton easier than spraying it on. If your a die hard racer than spray it on, otherwise just roll it on, the speed you'll loose is minimal. If you have a true race boat than you have all other kinds of worries. Of course I'm talking about a fairly commen type of paint such as Petit Trinadad or ACP-50. These paints roll on easily and if your hull and rudder are faired you'll have no adverse performance problems.
