I cut more 1/8″ mahogany plywood for the under-deck ceiling panels on the port side, then took them home and put on a couple coats of Minwax urethane varnish. It’s not as tough a product as the ICA two-part catalyzed clear I’ve been using for all of the major interior paneling, but for closet interiors and other places that will never see direct sunlight it’s fine.

First, measure the gap every six inches

Marked off and ready to cut

Nice fit!

Plenty of space for Buffalo Batt Insulation

Two coats of Minwax later…

Time to test fit



Not bad!

Needs a batten to join the panels

Like that!

Pay no heed to the grain orientation
I’m using up the 1/8″ plywood scraps here, and I don’t care about grain orientation since the only people who will see these panels are the owner when it comes time to winterize the boat and put the ER vent panels in place, then recommissioning in the spring. They’ll be hidden behind a built-in settee.

Another batten to join the panels

The last outboard mahogany cleat is fitted

And the last panel is cut
I’ll varnish that panel then remove all of them, seal and insulate the backsides before I do the final glue-and-screw installation.
