Bilge pump for water ballast tank

I know that our boats :macm: and :macx: are designed to be beached. But I am worred about getting stuck on a sand bar.

I was thinking about cutting a 3" hole next to the vent hole just big enough for a bilge pump. Should I get stuck and not be able to back up with the motor, I would remove the 3" cap, pump out the ballast.

Good idea or an over kill :?:

Overkill, I'd say. Just plumb a raft inflator at the vent, open the fill valve, flip the switch and foomp! -- Away you go.

Overkill !!!!! As Rich says, use an inflator to blow the water out. You would be using a dual purpose tool and not have to run drain hoses. Just remember to only open the fill/drain valve about 1/4 inch so that you blow the most water out before the bubbles start escaping.

We often let our X go aground from lowering tides. A nice, level, sand or mud bottom makes for wonderful sleeping. A thought came to me last time out. Once we are hard aground, and maybe high and dry, open the fill/drain valve and allow the ballast to drain out. Then close the valve and we float off in a couple less inches of water than what we went aground with. That allows us to leave earlier.

That's exactly what I was thinking. Just stick a 12v raft inflater to the vent and let it go. I've never tried this but I'm going to one day.

Dave,

It will be awhile, maybe Cayo Costa. I would have come to BEERs this year but signed up to do a Cheasapke Bay trip. It leaves Monday so Pensacola to Deltaville would have been a long haul. That one should last 23-25 days. Great.

Then I'm hoping the New York trip they are talking about jells. There would be a week break between those two.

Hi to Teresa.

Ken

Has anybody actually done this on an X or an M?? I tried using a High Volume Foot Pump and It didn't work.. You need among other things a real good seal at the vent in the V berth! There's a bit of pressure involved and you really have to exert force to hold the hose in tight..Your pushing a lot of water out!!
I ... had to then, try and close the rear valve.... humm... I now use my rare water wash down pump operated with a 12 V solenoid ( ballast or thru hull pick up) to pump it out of the ballast tank.. it takes about 15 minutes and I am free floating..

So has anyone yet, to do this with the HVLP 12V pump? I am still happy with my wash down pump system being used to pump out the ballast.
That Said.. My wash down pump and thru hulls and switches for my wash down and my macerator for the head, are all located close to each other.
