I have an old sailboat. The head doesn't have a holding tank. It
discharges overboard. I wonder, can I get a holding tank but not drill
through the deck for a pump out? The thought of drilling through my old
deck for a pump out that I will hardly ever use is crazy. But, I would put
a holding tank in to be legal.

Tell me about holding tanks with old heads.

You can buy for about $100 a five-gallon holding tank that fits around the
toilet. I think Raritan makes it. We had one on our old 1976 Dawson 26
completely plumbed for overbaord or pumpout. Small boat, very compact
solution. We now have one in the forward head on our 37 but we never got
around to connecting it and that head still pumps overboard. Looks like it's
connected but it's not. This tank can be plumbed like a port-a-potty so that
you can disconnect it and take it ashore to empty. I'll plumb it one of these
days. Our aft head has a Lectrosan on it. So we have, you might say, a number
one head and a number two head.
