Features

  • CHEAP CLAMPS SLIDE OFF AND DUMP YOU IN THE WATER: Most clamps slip when you lean back or set a hook. This mount has powder coated steel with PVC coated legs that grip the bench instead of bare metal on aluminum. No scratches or dents on your boat.
  • TIGHTENING TOOL INCLUDED: Other clamps make you reach blindly under a mounted seat to tighten wing nuts you cannot see or grip. This kit includes a rod that reaches under the seat so you can fully secure the clamp in seconds without skinned knuckles.
  • 360 DEGREE SWIVEL THAT WILL NOT SEIZE: Metal ball bearings rust and lock up in saltwater. This uses plastic bearings that never corrode. Firm out of the box and breaks into smooth free rotation once the seat is mounted and you start using it.
  • FITS BENCHES FROM 9 TO 18.5 INCHES WIDE: Works on jon boats, bass boats, aluminum boats, and any flat bench seat. The 5 to 6 inch bolt hole pattern fits most standard boat seats. Clamp width adjusts with threaded rods and wing nuts for a custom fit.
  • POWDER COATED FOR SALT AND FRESH WATER: Carbon steel frame resists rust and corrosion. PVC coated legs protect your bench from scratches and dents. No bare metal on your boat. Better Boat is a family owned American company in Miami Beach, Florida.

  • Excellent Customer Service
Size: 9 to 18.5"
I purchased 2 of these back in December 2024, and in May of 2025 on one of the seats, the plastic piece at the bolt hole broke. It was irreparable. I contacted Better Boat directly through email on their website. same day i got a response and Better Boat replaces it for me, and had it mailed to my house within a few days. Excellent customer service. I will buy their products purely for the interaction I had with the company. Anyone that can fix an issue in that way that quick has my vote. ... show more

Size: 9 to 18.5"
Put it on a 8' dingy for my husband with a bad back. A little tricky tightening with their tool, but was able to secure it tight. Great swivel.
