Corner dock wheels help you get into your slip when crosswinds or currents are a challenge What They Do
Fenders act as a cushion between a boat and a dock (concrete, metal or wood) or another boat and prevent damage to your boat’s topsides.
How They Work
Using either an inflated bladder (usually roto-molded vinyl) or soft foam, cylindrical, spherical (round) or flat fenders absorb the shock of vessel movement so that neither the vessel nor what it is bumping against are damaged. They insulate the boat from damage and decelerate it as it surges and rolls about.
Boats that tie up to floating docks usually set fenders just above the waterline to maintain a buffer zone between dock and boat. Boats that raft together place the fenders at the point of contact—generally where the beam is the widest. Docking next to pilings presents a special challenge: the pilings tend to push the fenders aside, with damaging consequences. A solution is to use a fender board that spans the distance between pilings. With the fenders and board, a boat can ride reasonably comfortably against a wharf.
Tuff End™ round fenders are great for raft-ups, and are often used by commercial anglers, as mooring buoys or starting line markers for sailing races All the Comforts of Home
Boats with permanent slips often customize their space, installing dock guards, dock wheels or cushions so that the dock carries the protection, not the boat. Since these forms of padding can be placed right at the point of contact, they won’t swing out of the way. Dock cushions can prevent damage when fenders are not lined up precisely. There are so many types of padding configurations that, with a little creativity, you can defend any style of boat from damaging, splintering, gel coat grinding objects.
Fender Styles
Round fenders are popular for larger powerboats with concave bows and larger commercial vessels (especially commercial fishing boats). Orange round fenders are also used as low-tech mooring buoys.
Cylindrical fenders are available in three styles:
Two eye fenders have a molded-in fairlead or tab at each end. Tie a line to one end only and hang the fender vertically or tie both ends for horizontal deployment.
Center rope tube fenders (Big B and one type of Survivor Series fender) allow you to hang the fender either horizontally or vertically using one line running through the centerline. A figure eight knot in the end of the line, or two figure eights at both ends of the fender are used to keep the fender from sliding.
Flat fenders
are either modular or articulating and vinyl-covered. String together the modular style to create a custom-fitted system. Hinged vinyl-covered flat fenders wrap vertically around small boat gunwales, and are great for boats with tumblehome (topsides that slant inward at the gunwale).
Center rope tube style Survivor™ fender. Thread a line through with a couple of figure eight stopper knots, or use the Big B Fender Hanger for either vertical or horizontal deployment. Transom mounted fenders
protect a boat’s transom or swim step when docking stern-to (Mediterranean style) in a marina.
Rafting Cushions
are designed for rafting boats together, and can be tied to pilings using the two rows of center holes. Large surface area, six independent molded tubes, versatile mounting options, and they won’t roll or ride up.
Low freeboard fenders
sit high on the hull and hang inward over the gunwale. The smaller size protects boats that sit low in the water, like bass, fishing and ski boats. The larger size prevents bigger boats from riding up under high docks when the tide rises.
Tuff End fenders:
Rugged large diameter heavy-duty fender with good protection for flared, deep-V hulls. They’re popular for large boats and commercial applications. Trivalve can be inflated easily with any kind of pump.
V-shaped Freedom Fender
with a self-centering shape will stay on a piling regardless of boat movement. They’re sized for everything from small boats to mega yachts.
We’ve got lots of specialized fenders to protect your boat, like this transom fender used on a swimstep. Pontoon fenders, such as the Fence Saver II, Pontoon Curve Protector and Pontoon Protector 90, are available in specialized shapes. They protect the delicate aluminum fencing and unusual corners on pontoon boats.
What size do I buy?
We recommend large fenders because large diameter fenders are the best way to provide protection. It is, after all, only the width of the fender that separates the boat from the dock.
We like roughly 1" of diameter for cylindrical fenders or 2" of diameter for spherical fenders for every 4'-5' of boat length. This is not a firm recommendation, because fender size also depends on location, boat weight and conditions. Boats in unprotected end ties on Lake Erie, San Francisco Bay or other locations with nasty chop or tidal surge will need more protection than a vessel docked in a calm lake. We suggest using proper lines or fender whips to suspend the fenders at the correct height. Here are some general sizing recommendations: |
