I'm guessing your talking about a trailor sailor , if you are We had one and other than: comfortable PFD's, Basic Map GPS
, VHF radio
pannels for the flat screen
TV, new sails
and updating rigging
, bottom paint
, cost of truck to pull it, tune up on out board, at least 2 anchors, mooring
buoys, running all lines to the cockpit
, If the boat
your looking at already has these things there's no real cost.
Oh yes there is probably a boating
test/licence also tab's and tax licencing yearly.
Good luck!! Some times I wish I still had our 26ft trailor sailor.
