Another baby step back to the water today. I decided to finish off my new hatch boards.

New hole saw in hand i put in the vent holes in the top board.

I found myself with three little wheels of ply. So have setup a small experiment.

The ply I used was “exterior grade” not marine ply. I’ve sealed all the edges well and put a fair few coats of epfaines varnish on, but still want to see how good this ply is.

So, I have one disc in a tray of horrible rain water with algae, another unsealed and the last with a light coat of varnish on the cut edges.

I’m hopeful that even the submerged disc will be fine but, only time and rain will tell.
