Find cylindrical fenders, round fenders, inflatable fenders, dock bumpers, mooring buoys, fender boards, dinghy fenders, fender lines, covers, holders, pumps, valves, and docking accessories.
Match fender size and style to boat length, freeboard, hull shape, dock type, rafting plans, tide, wake, and storage space.
Fenders work with dock lines. Set the lines to control the boat, then place fenders where the hull may touch the dock, piling, wall, lock, or another boat.

Sizing
Choose Fender Size Around the Boat and the Dock
Boat length is only the starting point. Freeboard, hull shape, displacement, dock height, pilings, wake, rafting, and how often the boat visits unfamiliar docks all affect fender choice.
Storage
Carry Enough Protection Without Crowding the Deck
Extra fenders are helpful for rafting, fuel docks, locks, transient slips, and unfamiliar approaches. Use holders, racks, covers, and storage bags to keep them ready without creating clutter.
Match the Boat
Consider length, freeboard, hull shape, displacement, finish, and where the fender will contact the hull.
Match the Dock
Floating docks, fixed docks, pilings, seawalls, locks, and rafting all need different fender placement.
Set Before Approach
Rig fenders before docking so the crew can focus on lines, wind, current, and safe movement around the boat.
Placement & Care
Place Fenders Where Contact Will Happen
Fenders should sit between the hull and the contact point, not just hang from a convenient cleat. Adjust height for dock edge, piling shape, tide, freeboard, wake, and the boat's movement on the lines.

Fenders FAQ
Choosing Boat Fenders
What size boat fenders do I need?
Start with boat length, then consider freeboard, displacement, dock height, pilings, wake, rafting plans, and storage space. Size up for exposed docks, heavy boats, or unfamiliar mooring situations.
How many fenders should I carry?
Many boats carry at least several side fenders, with extras for rafting, fuel docks, locks, and unfamiliar slips. The right number depends on boat size and docking conditions.
What is a fender board used for?
A fender board spreads load across multiple fenders and helps protect the hull near pilings, locks, rough walls, and work docks.
Should I use fender covers?
Fender covers can reduce scuffing and improve appearance, but they should be kept clean so trapped grit does not mark the hull.
