Definitely check your mast step, even if your rigging
does tune well. This is a common failure on this boat, but not too hard a fix.
My other concern on this boat is the plexiglas portlights-these are too lightweight (1/8") and could be entirely blown in by a broadside from a breaking wave. At the very least I'd want covers I could bolt over them if I knew bad weather was coming.
As for carrying extra fuel
, you probably have an Atomic 4, right? I'd rather run low on fuel
than carry jerry cans of gasoline, unless you can secure them well and protected.
I'd get to know your boat very well before I'd feel comfortable doing the planned trip. I think the boat is capable if it's in A1 shape, but you want to know where all the weak points are and fix them first.
