Signed up a 4th partner to the good ship Aquarius this weekend. Everyone has a 1/4 equity share buy in at $20k and then $150 a month for slip fees, insurance, property taxes, etc. When you leave the partnership, you sell your share to the next partner. I was in another partnership for 17 years on the Newport 30 Addiction. Instead of paying almost $10k a year, we each pay $2500. Much better! And we still get to sail as much as we want. At $150 a month, that's $5 per day to own a 40 footer in great shape that sails as fast as she is sexy! If you want to sail on a budget, partnerships are the way to go.
