Slammer Marine
Slammer Marine straight dock fenders are dock mounted fenders that line the horizontal face of a dock. They protect the entire length of the slip from end to end with no gaps, no slipping fenders, and no ropes to manage. Three profiles cover every use case: the Standard for mid-size to large vessels, the Small for lighter craft and tight docks, and the Fleece for finished hulls that need the gentlest possible contact surface.
A straight dock fender runs horizontally along the dock face at the height where a vessel’s hull makes contact. The polymer mounting track screws to the dock face. The foam-and-cover assembly slides into the track. The fender sits at exactly the right height and does not move. When a boat comes in, the protection is already in position at the point of impact, regardless of how the boat approaches.
The tear-shaped profile on the Standard line distributes impact energy across a wide lateral face so neither the boat nor the dock takes the full hit. Low-freeboard vessels cannot slip under the fender because the lower edge of the tear-shape sits below the typical waterline contact zone. Higher-freeboard boats hit the wider upper portion. The same shape works across a range of hull sizes without adjustment.
The Standard Fender is the original Slammer dock fender and the flagship of the line. The 9-inch by 6-inch tear-shaped profile is sized for mid-size to large recreational vessels (20 feet and up), marina slips, and high-traffic fuel docks. The Standard is the right answer for most residential dock owners and almost every commercial application. Sold in 40-inch, 80-inch, and 120-inch lengths in six standard colors.
The Small Fender uses a 5-inch by 3-inch profile sized for lighter watercraft, dinghies, sailing programs, sailboats with shallow hulls, and tighter dock layouts where the Standard is taller than needed. The Small mounts vertically or horizontally and is the choice for residential docks with smaller boats and for sailing schools that run optimist and small dinghy programs. Same modular construction, same colors, same warranty.
The Fleece Fender swaps the PVC outer cover for Polartec heavy-loft fleece. The fleece surface is gentler against gelcoat, varnish, and finished fiberglass than PVC, which makes the Fleece a popular upgrade for owners of fiberglass-hulled boats and finished classic boats. The Fleece is a private-dock upgrade, not a commercial product. The fleece fades faster than PVC under heavy UV exposure (the fleece carries a 1-year warranty; most customers report two to three seasons of use), and replacement fleece covers are sold individually so the fender does not need to be replaced when the fleece does. Fleece is rarely the right choice for a fuel dock or high-traffic marina installation.
Every straight dock fender uses the same three-part modular build. A 2-pound XLPE closed-cell foam core handles the impact load and resists waterlogging, compression, and shape distortion. A 30-ounce PVC-coated marine fabric cover (or Polartec fleece on the Fleece line) wraps the foam and takes the surface wear from UV, salt, and abrasion. A polymer mounting track with stainless steel deck screws fastens the assembly to the dock. The track is rated for lifetime use. The foam core lasts 8 to 10 years under normal use. The PVC cover is the typical wear part, with most customers replacing covers after 5 to 7 years. All three components are sold separately as dock fender parts so the system can be refreshed component by component instead of replaced as a whole.
Straight dock fenders are designed for dock surfaces that present a flat, horizontal face to approaching boats. That covers:
