Centreboard Replacement - From Compost to Completion. DONE!

DONE Many thanks to the kind members of the UK Gull facebook group for their encouragement and for providing the missing details required to replicate Ingrid's centreboard. Compost Some photos of Ingrid's centreboard as received. A large section was missing and what was left was crumbling. This hole is bored though the trailing edge of the centreboard, it received a locking pin which secured the board in the retracted position for trailering or beaching. Photos of a UK-based Gull centreboard, detailing the missing section. (Thanks Simon!) The photo and discussion also explained the mysterious bit of hardware in a box of stuff included with the boat. This is an adjustable friction brake that fits in the slot at the top of the board. It compresses 1” od rubber heater hose enough to span the centreboard case, resisting the board's swing. Trial fit and hole marking. As with the pivot bolt reinforcements in the trunk, I decided to m...

Stem and Transom fittings

Ingrid had very few places to which to tie anything, and I noted as I scanned the internet that later boats and gulls had added some fittings for this purpose. I added some stout fittings adequate to secure the boat to both dock and trailer. The transom was straightforward however the stem required the installation of a fitted oak reinforcement , well bedded in glass-filled epoxy putty and then reinforced with two layers of 1708, making a solid stem post integrated with the fiberglass topsides.

Repair of centreboard trunk

This area appeared to be sound, but after the rot I encountered elsewhere, I thought I’d investigate a bit. I used a holesaw to biopsy the core, thinking I'd replace the disc by epoxying in a stack of fiberglass discs to form a waterproof bushing. The plywood proved to be soaking wet though not rotten. I decided that given the certainty of future water ingress, I'd rebuild this area. . The glass sliced for removal. The piece gently pried off. All residual glass, filler etc ground off. The sheet fiberglass pieces below were cut from the scrap inner transom panel that was removed. Waste not want not! The pieces ready. The fiberglass plate will be epoxied to 1/4" marine plywood which has already been bored for a stack of fiberglass discs. (also cut from the scrap.) The discs will form a solid fiberglass bearing for the centreboard bolt, and the assembly will be epoxied then glassed to the side of the trunk, and to the ...
