Plywood core in hatches

[FELLOW-SHIP]

HA SCOTT
THE THING THAT COMES TO MIND FOR ME IS THE GAS TANK AND GAS FILL LINES IN THAT AREA. I HAD A NEW TANK MADE 12” HIGH AND I USED ¾ PLYWOOD FOR THE DECK THAT THE GAS TANK SITS ON. THE GAS FILL COMES FLUSH AGAINST MY HATCH. IN FACT IT CONCERNED ME THAT IT COULD RUB OR PUSH AGAINST THE 90 DEGREE GAS FILL BRACKET. I ELECTED TO CUT A AIR VENT/ ACCESS AREA OUT OF THE DECK AT THAT LOCATION FOR THREE REASONS FIRST TO PREVENT ANY RUB, ALSO FOR ACCESS TO THE FITTINGS AND MY GAS SENDING UNIT THAT IS ALSO IN THE SAME AREA AND FOR A VENT TO THE TANK. I REMOVED THE 4 VENTS THAT WERE ON THE OUTSIDE OF THE HULL THAT HELPED VENT THAT AREA WHEN I DID ALL MY HULL WORK. MY CONCERN FOR YOU WOULD BE THAT YOU GIVE ENOUGH OPEN SPACE IN THAT AREA “JUST ENCASE”. IF YOU ADDED ONE OR TWO LAYERS OF GLASS ON THE BOTTOM OF THE HATCH THAT WOULD STIFFEN IT UP AS WELL WITH OUT LOSING SOME OF THAT SMALL SPACE BETWEEN THE TANK AND THE DECK. THE SMALL CUP MIGHT GO AWAY WITH THE 1 OR TWO LAYERS OF GLASS IF YOU PUT THEM ON THE CONVEX SIDE. JUST A THOUGHT.
