You will also want to add at least one quality filter to the line - there are several threads here where they are discussed.
Saba Rock on Virgin Gorda (BVI) is a good pit stop every couple of weeks. If you take on fuel they let you fill your water tank, free.

Lessons learned are opportunities earned.
