Attwood Marine Quick-Release Gunwale Strap, 2 in x 13 ft

Overview

The Attwood Marine 15221-7 is a quick-release gunwale strap for securing the aft section of a boat to the trailer during transport. It uses 2 inch webbing and a 13 foot overall length, giving enough span to run over the gunwale and down to trailer tie points while helping limit vertical movement on the road.

This strap uses an over-center buckle that tightens quickly and releases by lifting the handle, so it is easy to tension at the ramp or in the yard without dealing with a ratchet. The webbing resists rot, oils, gasoline, and most chemicals, and the heavy-gauge J-hook includes a snap closure with an EDC finish to help fight corrosion around the trailer.

Key features

• 2 inch wide strap spreads the load better across the gunwale than narrow tie-downs
• 13 foot length suits aft tie-down runs from the boat over the gunwale to trailer anchor points
• Quick-release over-center buckle tightens fast and opens without ratcheting
• Heavy-gauge J-hook with snap closure stays attached more securely during setup and transport
• Webbing resists rot, oils, gasoline, and most chemicals
• EDC-coated hook hardware helps reduce corrosion in wet trailer environments

Compatibility and fit

This strap is meant for trailer use, where the tie-down runs over the aft section of the hull and connects to the trailer on each side. It is a good match for boat owners who want a broad strap path over the gunwale rather than a narrow point load, especially on setups where quick loading and unloading matters.

Fit depends on the distance between your trailer anchor points, the beam and height at the stern, and the strap path over the gunwale. The 13 foot length and 2 inch width are the main numbers to check against your trailer layout and the space available around cleats, rails, or other stern hardware.

Use on the trailer

For routine trailering, this style works well for boats that see regular ramp launches, marina moves, or storage-yard transport. It makes sense for owners who want a strap that is faster to tension and release than a ratchet while still keeping the stern held down against bounce on rough roads.
