Attwood 1002 Lock’N-Pin 3/4″ Seat Mount
The Attwood 1002 Lock’N-Pin is a zinc-plated steel seat mount with a 3/4″ steel pin and a spring for a “softer sit.” It features a 3-degree tilt and an installed height of 2 inches. Best for boats needing a compact, adjustable mount with a gentle seating feel. Consider this when you want a straightforward, low-profile pin mount that reduces seat movement while seated.
Best for: Small-to-mid-sized boats where quick height adjustment and a plush feel matter. Limitations: The tilt range is modest, so very high or dramatically angled seating may require a different style.
CLLOMAGY Boat Seat Base Mount Pedestal Base
This pedestal base is designed for 3/4″ pin posts and measures 7″ x 7″, suitable for most universal seat bases. It supports smooth installation with a deck-ready fit and provides stable swiveling action once mounted. Best for pontoon, bass, and fishing boats that require a sturdy foundation for aftermarket seats.
Best for: Decks needing a flush, universal base with easy drilling and six-screw securement. Limitation: Requires drilling and a precise cutout to sit flush on non-flat surfaces.
Attwood Lock’N-Pin 3/4″ Seat Mount SP-1002
The SP-1002 provides a versatile, comfortable perch for boat seats with a 3/4″ steel pin and a spring to boost comfort. The 3-degree tilt helps adjust seating position for better posture during long trips. It’s well-suited for boats needing an adjustable, reliable mount with a simple pin system.
Best for: Users who want a dependable, straightforward mount with tilt flexibility. Caution: Must ensure compatibility with pre-drilled patterns and seat hole spacing on older boats.
Shoreline Marine Boat Seat Mount
Shoreline Marine’s mount uses stainless steel with zinc plating, designed for 3/4″ pin-type mounting and a standard 7″ x 7″ seat base. Its robust construction and compatibility with common seating patterns make it a good pick for durable, long-term use on small fishing boats. Best for: Boats needing a heavy-duty, corrosion-resistant mount with traditional dimensions. Limitation: May not fit oversized or non-standard seat bases without adapters.
Attwood 15700-3 Seat Mount, Clamp-On With Swivel
The Attwood 15700-3 is a clamp-on swivel seat mount that extends 7.5 to 18 inches. It uses a steel frame with a black powder-coated finish for corrosion resistance. This option is ideal for boats with non-permanent seating needs or where clamp-on installation is preferred. Best for: Boats requiring flexible height and easy removal. Limitation: Clamp-on designs can limit access in very tight spaces or on surfaces with limited edge clearance.
Buying Guide: Key Purchase Considerations
- Mounting style: Determine whether you want a pedestal, clamp-on, or base-mount system. Pedestals are stable for extended seating, clamps are removable and good for boats with limited interior space, and base mounts provide a flush, permanent fit.
- Pin size and compatibility: Most common seats use a 3/4″ pin. Verify pin post compatibility with your existing seats or future upgrades.
- Adjustability: Consider height range (e.g., 7.5″ to 18″), tilt, and swivel capability. Wider ranges offer more ergonomic seating options on long days afloat.
- Material and finish: Marine-grade stainless steel or zinc-plated steel with powder-coated finishes resist corrosion. Avoid bare metal in saltwater environments.
- Weight capacity and stability: Heavier boats or high-action activities benefit from sturdy mounts with robust load-bearing construction and secure fasteners.
- Installation effort: Pedestal bases and base plates require drilling and alignment. Clamp-on options offer easier installation but may require edge clearance.
- Space and footprint: Measure available deck or bench space to ensure the mount won’t interfere with steering, pedals, or other controls.
- Maintenance: Look for smooth swivels and corrosion-resistant bearings to prevent seizing in saltwater or humid conditions.
Frequently Asked Questions
- What is the standard seat mount pin size for most boats? Answer: The standard pin size is typically 3/4 inch, but always verify with your seat base and post.
- Do clamp-on mounts damage boat benches? Answer: High-quality powder-coated clamps are designed to minimize surface damage when installed correctly; avoid overtightening and use protective pads if needed.
- Can I replace a non-swivel seat base with a swivel base? Answer: Yes, many swivel bases match standard 7″ x 7″ seat pedestal footprints, but check compatibility with hole patterns and mounting hardware.
- Are stainless steel mounts better for saltwater boats? Answer: Yes, stainless steel and zinc-coated finishes resist corrosion better in marine environments.
- Is a pedestal base more stable than a clamp-on system? Answer: Pedestal bases generally provide greater long-term stability, especially on rough water, but require a solid deck installation.
- What installation considerations should I plan for? Answer: Ensure enough clearance around seating, verify drilled hole sizes, and confirm that the chosen mount aligns with your seat’s pin post pattern.
