as a long time sailor i would be wondering how clean your bottom is<br /><br />a thin layer of slime will slow you down a lot a heavy enough one could keep you from even getting on plane<br /><br /><br />tommays

Neil,<br />Is this something new that just happened? Or has it been like this the whole time you have had the boat?

you did not waste your time <br /><br /> its and easy thing to check and far more common then you would believe <br /><br />if its clean look somewere else if not take a swim with a sotch brite pad <br /><br /><br />marine life on boats bottoms is different all over the place even different in the southern and northern USA<br /><br />tommays
