Boat Dock & Slip Financing
Building a new boat dock or purchasing a boat slip can cost anywhere from $5,000 to $50,000+ depending on size, materials, and location. Most banks don’t offer specific dock loans, making personal loans one of the best financing options — fast funding, no collateral required, and no restrictions on how you use the money.

How to Finance a Boat Dock
A personal loan is the most straightforward way to finance a boat dock. You receive a lump sum, pay the contractor or marina directly, and repay the loan in fixed monthly installments. Unlike home equity loans, personal loans don’t require an appraisal or put your home at risk.
Boat Dock Costs
Floating dock: $5,000–$20,000. Fixed pier dock: $10,000–$30,000. Custom dock with boat lift: $15,000–$50,000+. Boat slip purchase: $10,000–$100,000+ depending on location. Dock repair or replacement: $2,000–$15,000.
Personal Loan vs. Marine Loan vs. Home Equity
Marine loans are specifically for boats, not docks. Home equity loans offer lower rates but require an appraisal, take weeks to close, and use your home as collateral. Personal loans are unsecured (no collateral), fund in 1-2 days, and can be used for any dock-related expense.
