Which spare parts do you never leave dock without? I am trying to put together a plausible list of which items should be included on every voyage, and which ones would just be good to have. With only so much space in the work room, I can see reasons for hose clamps, wire, fuses, electrical components etc. What I am having trouble with is the "must have." Being gone from US waters for months at a time, I can see where spares could be hard to find.
