SternPerch® Seat Installation Instructions
Type #1 - Standard Installation

80% of all SternPerch seats are installed on boats with upper & lower rails. On these seats, the support legs are cut to the proper length, and the support leg flange is already installed.

SternPerch Type 1 - Standard Installation Step #1 – Insert drink holders. Be sure holder is inserted flush to seat, otherwise it may come out. Turn seat up-side down and stand on bottom to properly insert drink holder if needed.

Step #2 – Insert support leg into flange and secure it with provided Allen key.

Step #3 – Insert wing-nuts into clamps and attach seat to rail. Be sure to screw (not push) wing-nuts into clamps to ensure they are self-retaining.
Type #2 - Customer Assisted Installation

This installation is the same as Type #1, but in this case we did not have the position or length of the support leg because you provided us the seat pattern, so you'll need to install the flange and cut the support leg to its proper length.

  • Step #1 – Insert drink holders. Be sure holder is inserted flush to seat, otherwise it may come out. Turn seat up-side down and stand on bottom to properly insert drink holder if needed.
  • Step #2 – Insert wing-nuts into seat clamps and attach seat to rail. Be sure to screw wing-nuts into clamps to ensure they are self-retaining.
  • Step #3 – Determine leg position and length. Cut (polished aluminum) leg with hack saw, or tube cutter. Cut ¼" too long to start. Seat should lean back 5 degrees.
  • Step #4 - Attach support leg flange to bottom of seat with provided fasteners. Pilot holes for 10 x ⅝" screws should be ⅛" x ¼" into bottom of seat. If support leg is longer than 18", through bolts may also be provided. Suggestion: before drilling seat for through bolts, attach flange with screws to bottom of seat to ensure proper position.
Type #3 - Instructions for boats with only 1 rail

These boats (see Catalina 25 below) require a Rail Kit so the SternPerch seats can be installed on the lower rail, and you can lean against the upper rail. When the rail kit is ordered, we ask for the distance between the two stanchions.

SternPerch Type 3 - Single Rail Step #1 – Install clamps on stanchions, then affix the telescoping rail to clamps.

Step #2 - Insert wing-nuts into seat clamps and attach seat to rail. Adjust rail to proper height if needed.

Step #3 – Determine leg position and length. Cut (polished aluminum) leg with hack saw, or tube cutter. Cut ¼" too long to start. Seat should lean back 5 degrees.

Step #4 - Attach support leg flange to bottom of seat with provided fasteners. Pilot holes for 10 x ⅝" screws should be ⅛" x ¼" into bottom of seat. If support leg is longer than 18", through bolts may also be provided. Suggestion: before drilling seat for through bolts, attach flange with screws to bottom of seat to ensure proper position.
