Re: getting a Tartan 34C ready for offshore trip
Jeez! Do you have any room left for say, tools, food, water? Just kidding!
AFA the spare parts for the engine I would say get them vacuum packed w/ a silica gel dessicate inside to keep them dry and free of rust/corrosion. You don't want to reach for your spare and pull out a lump of rust.
I presume you have jacklines, if not, consider making them out of Amsteel (Spectra) instead of webbing.
