I bet if you did a simple inventory of the major items on each side of the boat you'd be surprised at the results.
My Tartan 28 lists slightly to port. Port side starting in the stern has an anchor and 3 batteries in the cockpit locker. Galley has a 3 burner alcohol stove and oven, and ice box with pop and water in it(sometimes beer
). Under the port settee is the 16 gallon fuel tank. Under the starboard quarterberth is misc supplies and spare parts. Under the starboard settee is a 30 gallon water tank(usually empty). And just forward of that is the head. With water in the tank she doesn't list as much, it is clear that most of the heavy stuff is on the port side.
Someday maybe I'll redistribute some of the items that can be moved...not a priority.
