<DIV style="font-family:Arial, sans-serif; font-size:10pt;"><DIV>Hi All,</DIV><DIV> Been learning a few things as I fix up my "Support Boat" ( 30' Islander Sailboat) . One thing that seems to work well for the sailboat humidity and condensation is the shag carpet which lines the V birth of my sailboat. Thinking about lining my sub with the same stuff ! Although without any rubber backing, which seems to be a problem, probably just Velcro it in wedges in the sphere, with a small round platform of teak at the bottom. Could also act as insulation. </DIV><DIV> </DIV><DIV>Brian</DIV></DIV>
