Attwood 17720 Seat Swivel, 360° Rotation

Best for boaters who value smooth, reliable movement without tilt, it suits standard boat seats and is a solid choice for anglers and casual cruisers alike.

It supports full 360-degree rotation and is designed for easy bolt-in replacement or mounting on new bases. Best for boat owners upgrading multiple seats or those needing a robust, rust-resistant solution. A potential limitation is the weight of stainless components, which may require reinforced seating frames in older boats.
Best for: Upgrading multiple seats with durable, corrosion-resistant swivels.

Buying Guide
What should you consider when choosing a boat seat swivel?
- Rotation and tilt: Most marine swivels offer 360-degree rotation; tilt is optional. Decide if you need tilt control for comfort or gear clearance.
- Materials: Stainless steel and powder-coated steel resist saltwater and sun. Stainless is best for rust resistance but may add weight.
- Mounting pattern: Check bolt hole patterns (commonly 4.75″–6.1″ or 5 1/4″). Ensure compatibility with your seat bases or pedestal.
- Load capacity: Consider user weight and seat cushions. Heavier-duty bases support longer lifespan in rough seas.
- Number of seats: If upgrading multiple seats, a multi-pack (like a 2-pack) offers cost and installation efficiency.
Installation and compatibility questions
- Can I replace an existing swivel without replacing the seat base? Yes, if the bolt pattern matches and mounting points align.
- Will these swivels fit pontoon chairs or captain chairs? Many are compatible with common boat bases; verify bolt pattern and base dimensions before purchase.
- Do I need special tools for installation? A standard set of wrenches and screwdrivers is typically sufficient; some models may require a drill for mounting holes.
Usage considerations
- Regularly inspect mounting bolts for tightness to prevent wobble and looseness during use.
- Keep hinges clean and lightly lubricated to maintain smooth rotation without squeaks.
- Balance the seat weight to prevent excessive stress on the swivel mechanism.
