As a leading supplier of marine products, Fisheries Supply offers a deep inventory of boat fenders and bumpers for boats of all sizes. Our selection includes trusted brands such as Polyform, Taylor Made, FatSac, and AERÉ. These marine-grade fenders help prevent gelcoat, paint, or aluminum damage when you’re docked, rafted up, or tied to pilings.

Choosing the Right Boat Fenders for Your Boat

Start with your boat length and freeboard, then consider where you dock most often: floating docks, fixed piers, pilings, locks, or rafting conditions. Larger or heavier boats typically need bigger, higher-capacity fenders. A common sizing rule of thumb is: about 1 inch of cylindrical fender diameter for every 4–5 feet of boat length, with larger round fenders for the same length range.

For day-to-day docking on typical recreational boats, inflatable fenders are popular because they’re light and easy to stow. For bigger boats or demandinger contact points, many owners prefer non-inflatable or heavy-duty vinyl/foam options. Manufacturer sizing charts should be treated as a guide, with final selection based on hull shape and local conditions.

Benefits of Using Boat Fenders

• Hull protection from docks, pilings, and neighboring boats.
• Safer boarding by reducing sudden contact and bounce.
• Fast setup with adjustable lines and multiple hang points.
• Adaptable coverage across different hull shapes and docking styles.

Types of Boat Fenders and Bumpers

We stock fender styles for common boating scenarios, from calm marinas to high-traffic raft-ups:

• Inflatable Fenders: Lightweight, easy to transport, and versatile for most recreational docking.
• Non-Inflatable Fenders: Durable, abrasion-resistant choices for heavier boats or frequent use.
• Pontoon Fenders: Shaped to protect aluminum rails and pontoon tubes.
• Personal Watercraft (PWC)/Jet Ski Fenders: Compact protection for smaller craft at docks or trailers.
• Transom Mounted Fenders: Designed for stern-to docking to cushion swim steps and transoms.
• Rafting Cushions or Bumpers: Helpful for raft-ups or tying to pilings in open water.
• Corner Dock Bumpers: Extra cushioning at dock corners where contact is most common.

Many premium fenders use marine-grade vinyl with reliable inflation valves, especially in Taylor Made product lines.

How to Choose the Right Boat Fenders for Your Boat

• Size: Use brand size charts and boat length rules; even small boats benefit from at least two, and ideally three, fenders for balanced coverage.
• Material: Look for UV-resistant, salt-tolerant construction such as vinyl-coated air sacs, molded plastic, or foam rubber.
• Shape: Choose cylindrical, round, or flat styles that match hull contours and dock geometry.

Dock fenders and boat bumpers are a low-cost way to prevent high-cost hull repairs. For larger boats or exposed slips, stepping up to large-diameter fenders adds margin for wind, wake, and uneven dock faces.
