WHERE THESE NUMBERS COME FROM
Where these numbers come from.
Slip fee is the biggest variable. In premium markets like Newport Beach, Marina del Rey, or Annapolis, a 40–50 ft slip runs $2,000–$3,500/month — that's $24K–$42K/year before you touch insurance or maintenance. Enter your actual slip fee above for an accurate total; the general estimate is calibrated for non-premium markets.
Insurance + maintenance + fuel are estimated from a per-foot annual rate that varies by boat type and region. Sailboats run leaner than yachts; the West Coast and Northeast run higher than the Great Lakes or Gulf Coast.
Financing is NOT included. If you have a boat loan, add that on top. Partnership shares are typically sold for cash so financing is the buyer's problem, not the boat's.
The equity payment is real money. When partners buy in, they pay you for their share of the boat — that's a one-time cash event on top of your ongoing cost savings. Enter your boat's market value above to see the full picture.
Use days matter for cost-per-day. A $15K/year boat used 10 days a year is $1,500/day. A $15K/year boat used 40 days a year is $375/day. Sharing changes both the annual and the per-day math.
