I have a 1984 Hunter 30. By all accounts this is a Bay boat, not a bluewater boat. I'm thinking of removing the overboard head components to simplify the plumbing and having a holding tank-only head. If this boat won't be used outside the Chesapeake Bay, it will never be where flushing overboard is legal. Foregoing discussions about the expense of simplifying the head and how doing so will effect resale value, is there any reason not to do this?

Thanks.

Most recommendations are to remove what isn't necessary but leave the thru hull closed and capped so that a future owner has the flexibility to use an overboard discharge if he chooses in the future to move the boat where he can do so. It's easier to leave the thru hull than to remove and fiberglass over it and then the next skipper has to drill another hole. Otherwise, nope.

This is what I did. In addition to capping the thru hull, the work consisted of removing a bunch of extra plumbing and adding a hose to hose barb in the place of a tee. About two hours all told.

Cool. I didn't realize the seacock could be capped. Sounds like a plan.

Did this a few years ago. Took out the macerator, plumbing to the thru-hull and capped the outlet in the holding tank.

The extra thru-hull is now the inlet for my wash-down pump for the anchor.

All is completely reversable. Wiring is still intact for macerator, plumbing is easy to hook up and thru-hull is still in place...... however, I doubt this boat will ever require it in its lifetime..... but, never say never...... :D

I should also mention that I purchased a 1.5" bronze (not brass) NPT cap for about $10 at a plumbing supply specialty store, as compared to the $30 or so I seem to recall it being at WM.

I used some Sika 291 that I had laying around to seal the pipe threads.

I would just plumb it so everything go into the holding tank. It is layed out in the holding WM catalogue as their "favorite method". This is a simple solution and you have something the next owner can live with too.
