I have removed an old depth and speed instruments which had been mounted on the front side of the Starboard Lazarette which even young eyes wouldn't have been able to see from the helm. I now need to cover the openings and don't wish to use teak. I have been told that I can use some very thin white board of some sort perhaps available at Home Depot and then glue using 5200. Does anyone know what this is and do I have to purchase a 4 x 8 sheet? Thanks, Greg W

Glass and Gelcoat or risk water infiltration

Not entirely sure but I believe this to be a fiberglass panel. If so you really need to core-glass and gel coat or you are going to have water getting into the core. Working with fiberglass is not that hard. It is very similar to working with drywall as far as the approach to filling the hole there are just more layers to deal with.

Perfect project for circles (or rectangles)

of hdpe (high density polyethylene), starboard, good plywood, or other durable plastic. HDPE comes in the form of cheap cutting boards from Wal-Mart or similar stores. Put a piece of plywood or more HDPE inside the hole, make a circle of 20 year silicone or 5200 around the hole, and screw the outside piece to the inside piece through the hole. If there's a possibility of storage, put in a round plastic hatch and maybe build a shelf behind the hole.

Cutting Board

I used a thin piece of cutting board that I bought at HD to cover an old instrument hole on my boat. I trimmed it to the necessary size. The white cutting board is the same thing as starboard and costs a lot less for the size that I needed.

Boatyards usually have star board, sell scrap by the pound. Sailors Exchange in St Augustine has bunches, its cheap. One thing it uses a special glue, I got the 2 part apoxy glue and the applicator gun from Granger. I've used it to cover holes like this and its works great. The other course of action is to glass it in, and gel coat. Somewhat difficult to get the gel coat color to match though but can be done with some playin around.
