Boat Seat Swivel Base Mount, Clamp On

The clamp-on boat seat mount with a 360° swivel is designed for jon boats, bass boats, kayaks, and skiffs with bench seating. It fits mounting holes from 7.5 inches to 18 inches, making it adaptable to a range of pedestal configurations. The base is made from galvanized steel with a black powder-coated finish for rust resistance, making it suitable for harsh marine environments. Best for boaters who want a straightforward install and full swivel coverage without tools. A potential limitation is that very wide or unusual hole patterns may require a separate adapter.
Attwood SP-15900 Tilt-N-Slide Seat Mount Set

This Attwood kit offers a bench-style seat plate on 15-inch rails, expanding seating versatility and comfort. It’s ideal for job boats or other craft needing smooth sliding for easier access and seating adjustment. Aluminum construction provides corrosion resistance and lighter weight. Best for users prioritizing a larger sliding range and a robust aluminum frame. Choose this if you want a long rail system; avoid if you need a compact, single-mount solution because rails add length.
Clamp On Boat Seat Swivel Mount (MANUMARINE)

Two installation options are offered: clip-on for zero tools or screw-in for maximum stability. It delivers a smooth 360° swivel, letting you rotate easily to face gear or watch the water. The unit uses heavy-duty galvanized steel with a black protective coating to resist saltwater and corrosion. Best for boaters who want quick setup and a durable, long-term solution. A potential caveat is that the clamp’s fit may depend on boat bench width and seat hole patterns.
Attwood 15700-3 Seat Mount

This Attwood model offers universal seat compatibility with a dependable steel build and a black powder-coated finish for corrosion resistance. It adjusts from 7.5 inches to 18 inches to support a comfortable seating position. Best for boats needing a well-rounded, widely compatible swivel base. Consider this if you want a known brand with proven steel durability; it might be heavier than aluminum alternatives.
SP-15100 Jon Boat Mount Plate

This aluminum mounting plate is designed specifically for Attwood swivl-Eze seats, offering a lightweight yet durable base for jon boats. It’s ideal for replacing or upgrading a fixed seat setup where a swiveling bench base is desired. Best for aluminum-focused builds and lighter weight setups. A limitation is that it requires compatible swivl-Eze accessories and is not a universal base for all seat brands.
Buying Guide
Key considerations for choosing a jon boat seat bracket:
- Mounting method: Clamp-on bases are quick to install, while bolt-on plates offer maximum stability on heavier rigs.
- Adjustability: Look for a range that fits your seating height and the boat’s layout. Common ranges are around 7.5″ to 18″ or up to 20″.
- Material and finish: Galvanized steel with powder coating provides corrosion resistance; aluminum offers lighter weight but may be less rigid in extreme loads.
- Swivel capability: A full 360° swivel improves visibility and control while fishing or navigating.
- Compatibility: Ensure the base plate or swivel integrates with your current seats or pedestal systems (Attwood, Swivl-Eze, etc.).
- Installation effort: Some options allow tool-free setup; others require screws or bolts for maximum stability.
FAQ
- Q: Are these brackets compatible with all jon boats?
A: Most are designed for common bench-seat layouts on jon boats, but compatibility depends on hole patterns and seat dimensions. Check product specs before buying. - Q: Which material lasts longest in saltwater?
A: Powder-coated steel and aluminum both offer good corrosion resistance; aluminum is lighter, while steel with coating tends to be more budget-friendly and robust. - Q: Do I need tools to install the clamp-on models?
A: Some offer tool-free installation via clipping, while others require screws or bolts for maximum stability. Choose based on how permanent you want the setup to be. - Q: Can I use a swiveling base with any bench seat?
A: Most swivels fit standard seat hole patterns, but verify the distance and mounting pattern to ensure a secure fit. - Q: Is a longer rail a better choice?
A: Longer rails provide more seating position options and can improve comfort on larger boats, but they add length and weight. Choose based on available space and use-case. - Q: What is the main benefit of a 360-degree swivel?
A: It allows turning in tight spaces to watch lines, interact with guests, and access gear without repositioning the whole seat.
