Jules,
All great questions and plans. Back up a little to help us catch up with you. Context. What boat (type, size, year, condition, etc), what planned use (where, how often, how long, with whom, etc), what budget (time, money, patience, etc) ... bore us with the details.
Thanks for the learning opportunity,
Mark Stafford
