Adjustable Seat Pedestal – 500/750 mm

This tall adjustable seat pedestal provides an extended height range intended for applications where the seat needs to be significantly elevated. With a span from 500 to 750 mm, it’s particularly suitable for flybridge helm stations on yachts, tall console helms on powerboats, or any situation requiring a raised seating position for improved visibility and control.

To ensure reliability at these greater heights, the construction is reinforced. The aluminum column is of a larger diameter or wall thickness to prevent excessive flex or wobble even when fully extended. The wide circular base (~220 mm diameter) is crucial for stability – it spreads the stress over a larger area of the deck, minimizing any wobble risk. It’s recommended to mount this base on a structurally sound surface and to use all the bolt holes for maximum support.

The adjustment and locking mechanism is similar to the shorter model: a telescoping inner post that is secured using a side clamping handle or a locking pin. Despite the greater height, the adjustment remains smooth thanks to quality glide components and precise fitting between the tubes. Once the desired height is set and locked, the pedestal holds the seat steady – with no sinking or play, so the seat stays secure as the boat moves.

As with the shorter model, anodized aluminum provides a dual benefit – high corrosion resistance and an attractive shine. Even with daily UV exposure and salt spray, the finish remains protected from oxidation. Cleaning is easy – the smooth surface doesn’t trap dirt or salt and wipes clean quickly.

Additionally, this model retains compatibility with standard seats and accessories. Its top is again designed with the universal hole pattern, which allows mounting of any marine seat, swivel, or slide. For example, if you want the flybridge seat to swivel, you can directly attach a swivel base (04315) on top of this pedestal. For sliding function, mount the track slider (04289) or combo unit (04265-NS) without modifications.

Safety tip: Because this pedestal allows significant height, ensure you always lock the height in place before getting underway. A seat at the highest position raises the occupant’s center of gravity – it’s recommended in very rough seas to lower the seat to a safer height for better stability. The pedestal itself is secure, but the higher position can be less stable for the person (due to physics, not due to pedestal weakness).

• Typical use cases: Mounting a captain’s chair on a flybridge, where the helmsman must be high above structures for a 360° view. Center-console boats with leaning post seats – the seat can function as a leaning bolster at the top position and a normal chair at the low position. Big-game fishing boats – tall fighting chairs or observation seats to watch trolling lines. Also for navigation stations on larger vessels where a standing or high-seated position is required.
• Advisory for use: At maximum height, avoid sudden lateral moves – although the pedestal is sturdy, the occupant sits higher and has more leverage relative to the deck. Using a seat belt or harness (if the seat has one) is advisable when in a high position in rough conditions. Always inspect the clamping mechanism – at this height it is critical for safety.
• Installation & maintenance: Installation is analogous to the 340–510 mm model – use quality fasteners and reinforce the deck if needed. The difference is that for this taller pedestal, it’s even more important to have a backing plate under the deck to spread the load. Maintenance involves the same steps: regular rinsing off salt, light lubrication of moving parts, and checking the bolts. Because the stresses at full extension are higher, take time to periodically inspect for early signs of fatigue – unlikely, but as a precaution, examine the aluminum post for cracks and check the condition of the locking mechanism. This preventative check helps ensure long-term safe performance.
