Let's start with the boat. I don't know what your sailing or what your
motor is but extra
engine filters,oil and filter and
water pump and
water maker
parts, Don't forget to top off and make sure your altenater has a spare. new
batteries would be nice if they aren't
AGM and around 3 years old, open and shut all seacocks before casting off,
electrical kit,
safety kit, ditch bag,
epirb if needed, and extra lines.
Sails in good shape and a spare for each.wax ring for plugging
leaks, FBR and matt just in case.
sewing machine, tool box full of tools, and pipe wrenches, and stainless rod and wire.
That's a start anyway.
