Can anyone help with the dimensions of the compac 23 mast support - where the deck has a wood backing plate ; I need to cut this deck area
off and replace the failed wood backing plate with g20 , need the size for ordering .

I caution all to not over think or over build any mast tabernacle.
They simply CAN sit on the deck with a chunk of 1/2 plywood epoxied on
to the underside of the cabin top. Actually replacement plywood chunks
goes in from the top, once the old wood is ground out. That's if you want
to keep the cabin liner on the typical XL looking stock.

Next your chose. Factory wood screws into the plywood. Or drill clean
through and bolted in place around the circumference of the compression post
or the cabin supporting arch.

This is not rocket science. I'll bet the factory doesn't spend 15 minutes making
and installing the the tabernacle with its plywood hard point.

skip.

There really is no supporting arch on the 23's but rather the bulkhead on either side butts up to the underside of the, for lack of a better word- cieling. It seems that the section of cabintop under the mast is quite thick. maybe 2 inches or so. That hunk seems to transfer the loading from the mast to the bulkhead walls and down to the keel.
