Checking in, and a Gray Water Tank Q

[Just Right]

Hello All,

Just bought our 95 270 DA from a family in Vegas a dragged it up to our home Folsom, CA. Wish we could have have stayed a few days and motored around Lake Powell (oh well).

Posted a little bio "Just Right" in the Who's Who forum with more personal details.

One issue we had with doing an overnighter in Emerald Bay on Lake Tahoe with our prior boat was we could not dump gray water overboard. Has anybody know of someone who installed a gray water tank on board?

I was thinking there might be room under a sole for a bladder tank. Then put a Y-valve in the two sink drains with hoses to the tank, divert the shower drain directly to the tank, and then use the shower sump pump to drain the bladder and pump the gray water off the boat into a suitable recepticle.

Watcha think? Open to ideas.

I guess I'm confused. When you say "gray water", you mean stuff from the showers, sinks, etc.? That stuff goes directly overboard on my boat (other than landing in a stinking sump box first). I did not know Sea Ray had a gray water system with a tank... news to me.

New Hampshire lakes also forbid dumping gray water. I had to get the gray water option on my 2005 300 DA. Sinks and shower drain into the shower sump. There is a pump there that normally pumps the gray water overboard. But with this system it goes into the black water holding tank. The same one that the vacuflush uses.

Obviously this fills up the holding tank pretty quick, so pump-outs are a lot more frequent.

Wow... what happens if they catch you washing your hands overboard or dumping the half eaten bowl of cereal overboard?

PUT HIM IN JAIL!

You telling me people that are out skiing all day don't pee in the water up there?! You are all big-bladder people in the NE!

My wife makes me wash my hands more often than a surgeon! I'd have to mount a holding tank on my swim platform. On my ole 270 there is quite a lot of room under the forward v-berth cushion. There was also a lot of room on the stbd side of the engine room.

BTW - Welcome to the board! Good luck!

jrcinnh has made a good point. The grey water should drain into a central sump from which it is pumped up and into a holding tank. This tank is preferably a dedicated grey water tank rather than the black water holding tank, but either could work.

My boat has a central drain system as described above, but since I have no grey water holding tank, the grey water is pumped directly from the sump overboard.

Don't know about the NE, but Tahoe is unbelievable in its restrictions. That's for boats on the water and for folks living in houses on the land. The regulations can seem un-American at times.

TRPA, Tahoe Regional Planning Authority, has nearly God-like powers. And uses them.

In NH, I actually had a DES (environmental) inspection to certify my grey water system. The state passed an amendment to prohibit the discharge of sink and shower waste as part of the "no-discharge" standard.There may be no means of overboard discharge, either directly or indirectly (RSA 487:2).

Seeings as people call these sport cruisers stern "heavy", I was thinking it would be nice to put up to 30 gal. of gray water somewhere forward of the engine compartment.

Anyone have knowledge of how the soles are attached to the hull? Would it be difficult to get access to those hollow sounding voids?
