When the deck is raised from the hull adequately one will see at the highest point of the hull structure a space between the inner hull and outer hull where it flares outward to match the deck lip. Within this gap there is wood measuring 4” long, 1-1/2” wide, ½” thick placed end to end from stem to stern. I call this area a gunwale, for it runs the length of the boat, not including the stern area.

On my boat I found 60% of this wood rotten. I suspect it is typical of this year and model.

Rotten core material partially removed

Made from 3/8 rod with chisel end ground.

Removal tool

This wood was installed during manufacture when the fiberglass resin was still wet, therefore is adhered slightly. Drive a sharp putty knife between the surface of the wood and glass, loosening it. Pry wood from core area. For removal of subsequent pieces I fashioned a tool from a 3/8” rod that resembles a “bail hook”, flattened and sharpened with a chisel edge on the hook end. I found that leaving the wood half inserted assisted in keeping the hull edge exposed for easier removal of subsequent pieces.

Removal tool

After removing all pieces I took a 3” wire wheel and brushed out the core surfaces, as well as the inside edge of the deck lip (to remove caulk).

Use compressed air to blow out all debris.
