Two types of seats typically are found in boats, bench seats and pedestal seats. Usually, a bench seat is used at the rear of the boat and a pedestal seat is used for the driver and front passenger. You can mount a seat in a fibreglass boat by first determining where it needs to sit. A driver and passenger need to be able to stand as well as sit when riding in the boat.

  1. 1

    Place the mounting plate or the seat base in front of the steering wheel. Position the plate so your arms can comfortably reach the steering wheel when you are seated.

  2. 2

    Mark the mounting holes with the felt-tip marker. Drill a 1-inch hole into the floor with the power drill.

  3. 3

    Fill the holes with the marine epoxy resin and allow it to cure for at least three days. The epoxy resin is used to prevent water seepage.

  4. 4

    Drill pilot holes one-half the size of the mounting bolts into the centre of the epoxy resin.

  5. 5

    Apply marine adhesive sealant for the area for the seat base. Apply the sealant to the bottom of the seat base and set it in place. Insert the lag bolts into the mounting holes.

  6. 6

    Tighten the lag bolts with the socket wrench. Allow the sealant to set for at least 24 hours before using the new pedestal seat.

Tips and warnings

  • A pedestal seat is also referred to as a Captain's chair or helm chair.
