for handheald, flashlights x 4, tool box with every tool needed to turn a bold or screw on your boat ( some will need doubles) patch kit for dinghy, plugs, shims, tape, duct tape, glass sheets
, glass tape, sail tape, sail thread, whipping line, rope
dope for ends, spare roll of every sise wire on board with approiate fuses
x2, spare fuel
cans, spare bilge pump
