The standard access hatch to the area behind the engine is a plywood panel glued and screwed in situ, with a small plastic screw hatch. It’s not very good. The bigger circular item is a base for a cockpit table. Below this hatch are the cockpit drain seacocks, the gearbox dipstick, the gearbox oil cap, the propeller shaft, the stern gland, the exhaust elbow, the exhaust box, etc, etc. That little screw hatch gives next to no access at all.
Spurred on by a post in the Cornish Crabber forum by Kevin Misselbrook, I decided to follow his lead and add a larger inspection and access hatch. It only took me 30 minutes, so is an easy upgrade for any other owners. Buy the hatch by clicking here.
This is with the plywood hatch removed, and you can see the sten gland and cockpit drain seacocks.
This is the hatch in place. All I needed to do was cut out a slightly larger hole with my jigsaw.
Here the hole has been enlarged and the screw holes for the hatch drilled though,
The hatch now sits flush and just needs loads of sealant underneath, before screwing down tightly.
That’s all there is to it. I wiped the excess sealant away with a rag, and that was it. I then covered it up with the new red cedar duck-boards make by my dad, Tony.
