I am looking for a place to hid the fuel tank out of the way. I know some use the laz and vent but I would rather not go that route. I want to keep as many fumes out of the cabin as possible. I saw a mod by Centerline where he added storage under the cockpit seat on a Mac 25. He built an insert out of aluminum to house the fuel tanks. I have 1/8 stainless sheets I could build a version out of. I assume the seats on a 26D have foam for floatation. My V berth already has had the foam removed. So I am ok with removing more foam as I am coming up with an idea to add some flotation back anyways. What are your thoughts?
