What boat you got ? Sailboat ( need another hand ? ) or Stinkboat ( lol ..... I dont mean it THAT bad ..)
Sailboat : every gram is important as you well know. You also want to look for a bike which has a lot of stainless steel, and less complicated the better. Better components usually do much better in salty humid conditions. Frozen brake shifter cables, rusted bolts and hinges, headsets and other bearings and so forth.....
my pick .. Dahon Speed 8
Thor
my pick has to be of course as I am a Dahon dealer :-)
