The previous owner had replaced the alcohol stove with a propane stove, but hadn't yet installed the propane tank. I will be installing 2 tanks in the aft lazerette. Since the boat didn't come with a tank, shelfs needs to be fabricated to hold them. I mocked up a shelf out of cardboard, and has a local metal shop make it. It took about half a day hanging upside down in the locker to get everything positioned and mounted. But it came out pretty nice. I still need to do some final dressing of the pressure hose to make it perfect.
