The ballast for your boat is lead and it is located in the belly of the boat. Under the v-berth is where the waste holding tank for the head is located. My electric bilge pump is located in the bilge just as you walk down the companionway steps. The original location for the freshwater tank was underneath the cockpit.
To redo or eliminate your head is tough to answer because no onew has seen it or knows anything about it. You need to tell us why you want to!!
Any other questions, fire away.
