I agree with the attitude of sail the boat for a while before you start spending on major (large budget)
gear. You will see dozens of arguments on this forum about
autopilot vs
windvane. Having both is the best answer, but for a
small boat with limited
battery power I would not go to sea without a
windvane. This is not a contradiction, but I would say to put off
buying a vane until you get to the
Carribean. There are vanes
for sale there from people that have crossed the Atlantic and dont need them anymore or cruisers that are broke or are trying the
charter trade and dont want a vane on the back. I bought an
Aries for $250 that worked wonderful. Something to consider when looking for a boat is the stern/transom, and if it is suitable for easy mounting of a vane. Boomkins, mizzen booms or anything else can make
installation much harder (expensive) and maybe make your vane
work poorly. I mention the
Aries (I have had 3), but it is probably too heavy for the size boat you are thinking of. There are many brands of vanes. Another point is that there are lots of boats in that size range that would do well, but dont live up to the hype of the Island Packets or Pacific Seacrafts, but also dont demand nearly as high a
price. The very Best to You._______Grant.
