Boris....quick questions. Are your cockpit drains underwater when you have a load in the back? If yes..... do you have seacocks on the drain line in case a line is compromised?

Thanks......Tom

During some nasty weather, I put on a long sleeve shirt and removed the old fishbox port/stdbd macerator pumps and the raw water washdown pump (intake is plugged with rubber stopper and sealant at intake).

Installed Tom’s DIY link arid bilge, but used ¼ rather than ⅛ as smallest tubing. It happily inserts into the ⅜ HD tubing I used for manifold and pump connections. For suction rather than pressure applications this works fine.

The $12 Amazon 12v timer does not work at all (no output voltage on the switch legs even on Manual when powered up with 13V). So I too am currently using it as needed with one of the many pump switches now freed up.

Tomorrow is predicted to be 81 degrees and sunny, and Jan 4 82 degrees and sunny, so they are beach days rather than boat upgrade days.

Dammit, there are just not enough bad weather days down here to get anything done.

Getting home soon so will attack the punch list then and see you next month, Tom!

Tom,

Funny you should have asked. When the cockpit is loaded or the boat is underway, the cockpit drains are plugged with wooden plugs. We found out that water will flow in through those "drains" shortly after the boat was new. Unplugged when the boat is lightly loaded or I'm washing it.

The builder (whoever that was) put in check valves when we complained, but the pressure head wasn't enough to open them and allow them to flow. I removed them.

Through a combination of common sense and wooden plugs, the cockpit stays dry. And through replacing the hatches, the bilge stays dry.

Boris are your plugs in the cockpit or in the thru hulls? I plug mine in the thru hulls. That way if a drain hose is compromised the boat will not take on water. I have had a hose fail. With my hatches totally sealed there is no where for the water to get out of the cockpit when it rains, showers, clean fish etc. In the future I’ll put sea cocks in then seal the hatches. I just don’t sleep well with the cockpit drains under water and unplugged. 😴

Thanks Tom

Tom,

Your logic sounds good.

I sleep well, because I only put the plugs in when I'm awake. Sometimes I forget they're in, but so be it.

I put them from the cockpit side. I replaced the original thru hulls with 316 stainless ones, mostly because the original ones started to corrode. Then I replaced the hose with good bilge hose. Of course this is long after the boat was new.

Remember that those thru hulls are mostly out of the water and only when the boat is still and the cockpit is heavily loaded are those thru hulls under water. I'm counting on the bilge pump to handle the incoming water until I notice and take action. No problem in 14 years.

Boris

Funny (not really) about cockpit drains being the source of incoming water,
what you don't want.

So, here I am with friends sailing from Funchal, Maderia to Antigua, yup mid
ocean early '84. Winds about 30K and we were booking along in the C&C61
at 12 K or so. After a bit, one day, the boat slowed to 8K and because of the
glorious weather, everyone (about 10 of us) were on deck enjoying.

Well, someone off watch headed for the head below followed by a scream
"We're sinking!!!". Belowdecks, the floor was water covered. Everyone
rushed below and started pumping the two manual bilge pumps.

Longer story short, what had happened was a fitting for an overboard bilge line,
having an antiphon loop (secured above the waterline), had failed letting the
outgoing bilge line fall below the waterline, on starboard as I vividly recall while
we were on a starboard tack, allowing water to run retrograde into the boat.

Those 20 minutes I do not care to repeat. I love water but it has to be on my
terms...

Take care out there!

Aye.
