The Megaware KeelGuard 20511 is the original do-it-yourself keel protector, engineered to defend your boat's hull against the damaging effects of sand, rocks, concrete ramps, and oyster beds. Unprotected keels are vulnerable to gelcoat breakdown, which can allow moisture to penetrate and destroy the underlying fiberglass laminates — the KeelGuard stops that damage before it starts.
Developed in collaboration with boat designers and 3M engineers, the KeelGuard is constructed from multiple layers including a UV-stabilized, abrasion-resistant polymer and urethane composite exterior, foam padding for shock absorption, and a 3M pressure-sensitive acrylic adhesive backing. The result is a protector that permanently bonds and self-seals its contoured edges directly to the hull surface — no messy sealants required.
Key Features:
- 11-foot length in Gray — UV-stabilized for long-lasting color
- Constructed from a durable polycor composite blend of polymers and urethanes for optimal abrasion resistance and pliability
- 3M pressure-sensitive acrylic adhesive permanently bonds and seals contoured edges to the hull
- Patented hydrodynamic drag reduction channels with angled grooves create air pockets for a slicker surface without reducing boat speed
- DIY-friendly installation — complete kit includes primer and all necessary application materials
- Lifetime warranty against abrasive wear and adhesion failure during normal use, for as long as you own your boat
- USA made
Installation Notes: Must be applied to the bare fiberglass or compatible aluminum surface — not over vinyl wraps, anti-fouling paint, or boat bottom paint. Install 4–6 inches above the resting waterline. Not recommended for boats where trailer rollers rest the full weight of the boat on the keel. Not compatible with kayaks, canoes, most catamarans, or pontoon tubes.
The Megaware KeelGuard is the proven choice for boaters who want to protect their investment and beach their vessel anywhere with confidence.
