Chain Plates

The forward chain plates were generally in good condition although coated in rust. Chain Plates00009

The rear chain plates were also extremely rusty but were attached to the topside through rotten timbers. Structurally all six rear chain plates were unsound and had to be removed and the supporting timbers replaced.

The forward chain plates were all sand blasted back to bear metal and then 2 coats of Jotamastic 90 epoxy undercoat applied. They were then painted with a two pack epoxy black enamel. All the rear chain plates were completely removed from the vessel.

The woodwork under the rear chain plates was replaced with hardwood bearers tied to the deck supports. This meant that both the port and starboard side rear top deck walls had to be removed and rebuilt. New 150mm X 150mm hardwood  bearers were inserted as primary support for  the chain plates. The exterior was then covered with 2 layers of epoxy treated 19 mm marine ply.

Prior to reinstalling the chain plates, all the new wood work was covered with fibreglass then sealed with two pack epoxy. The fibreglass covering was extended over the top deck and on to the sponson in order to ensure a completely watertight seal. New fastenings were used to reposition the chain plates and the port holes.
Each of the rear chain plates were extended and bolted bolt to new steel supports which were in turn bolted through the sponson. All steel supports, chain plates and extensions were sand blasted and then galvanised prior to installation.

  1. WOW – boat like $2M! My Chinese brother Shu-Yang Lo MD of Cheoy Lee shipyards Hong Kong, says wooden boats make him nervous – very hard to quote repairs as problems are exposed one after another!

  2. Tell me about it!! Hopefully we will see you guys in North Queensland for a leisurely cruise?
