Good heavy ground takle- a good bowyer 55lb delta

, and connector. Lots of chain with snubbers.
a couple of old tyres for docking
next to those rust ridden wharves ( DR etc)
Sanitation system that you can pump overboard
Some form of power generation- without a reefer 2 60 solar panels
A means of collecting water
, and foot pumps at sinks.
spares, if you include Venezuela
in your travels, carry some flex fuel tanks
to fill up where its cheap
If you have some speciality food
item you like bring that ( Nori, PG tips, Wasabi, Marmite, etc) and lots of it.
Self steering- non electrical
