Overview

The TACO Marine H25-0048 is a Command Ratchet Hinge with an 18-1/2 inch length, a hard stop at 105°, and one locking position at 62.5°. It is made for larger marine seat backs, sun pads, bolsters, and lounge backrests where the backrest needs controlled positioning rather than a simple free-swinging hinge.

This hinge mounts above the deck and is suited for seat backs up to 22 inches long and cushions up to 4 inches thick. The polished Type-304 stainless steel construction gives it a clean finished look for visible seating hardware while adding corrosion resistance for regular boat use.

For fit checks, the hinge measures 18-1/2 inches long by 3 inches wide. It is sold as a pair, meets ABYC H-31 Class B application requirements with a 500 ft-lb torque load rating for the pair, and has passed a 500-hour salt fog test.

Installation and fit

This hinge is a strong match for builders, refit shops, and owners replacing or upgrading seating hardware on cockpit lounges, aft-facing seats, convertible sun pads, and bolster assemblies. The 18-1/2 inch length gives more support than a short hinge on wider or taller backrest panels, while the 3 inch width should be checked against the mounting surface before drilling.

Because it mounts above the deck, the hinge location, fastener access, cushion thickness, and the swing path of the backrest should all be confirmed during layout. The hard stop and locking angle are part of the hinge geometry, so both hinges in the pair should be aligned evenly for smooth movement and even load sharing.

Use cases on board

On center consoles, day boats, cruisers, and fishing boats, this hinge works well where a seat back needs to stay put in a usable position and stop before over-traveling. It is especially useful for lounge seating and convertible deck seating where passengers may lean against the backrest while the boat is underway or while anchored.

Materials and care

The polished stainless finish is suitable for visible marine hardware, but it should still be rinsed with fresh water after salt exposure and cleaned with products made for stainless steel. Routine checks of the mounting fasteners and hinge movement help keep the seat back secure, especially on boats that see vibration, trailering, or frequent washdowns.
