Pedestals - Lock'N Pin

A boat seat pedestal is the post-and-base assembly that lifts a helm, fishing or lounge seat off the deck and holds it securely while you cruise, cast or troll. The Lock'N-Pin pedestal is a specific style built around a 3/4-inch pin that drops into a base plate, letting you add, remove or swap seating without tearing up the deck. It is a popular choice for fishing, pontoon and cruising boats where seating layouts change from trip to trip.

What Makes the Lock'N-Pin Design Different

The defining feature is the patented locking mechanism that gives the system its name. It is designed to prevent unintentional detachment of seat mounts, posts and bases, so a seat doesn't come loose when a boat hits chop or a wake. Lock'N-Pin components are also rated to meet ABYC Standard H31.6.1. Because the pin is steel, the connection holds up to repeated loading, while the posts themselves are typically brushed aluminum for light weight and corrosion resistance around water.

Key Considerations When Choosing a Pedestal

• Fixed vs. adjustable height: Fixed posts, commonly offered in heights such as 11 or 13 inches, are simple and economical. Adjustable and power pedestals let different passengers dial in comfort, with ranges such as 14-17 inches or 24-30 inches.
• Threaded vs. non-threaded: Posts, pins and bases come in threaded and non-threaded versions. Make sure the pieces you pair are compatible.
• Base plate material and size: A 7-inch by 7-inch base plate is common, and bases are offered in aluminum or stainless steel. The plate is typically fastened to the deck with bolts or screws.
• Seat mount: Some posts include an integral seat mount, while others need a separate mount, such as a spring-loaded version with a slight tilt, to attach the seat.
• Removability: A removable pin post lets you take the seat off and set it on a low-profile base for storage or transport.

Why It Matters

Seat hardware is easy to overlook until it fails. A wobbly or loose pedestal affects comfort and, more importantly, safety when the boat is underway. Choosing a pedestal with a positive locking pin, corrosion-resistant materials and the right height for your seating position helps your seats stay put season after season. Always confirm pin diameter, thread type and base compatibility before you buy so your new post mates cleanly with your existing hardware.
