Hoses in the bilge of Cherubini 33

[HermanHunter]

Hello to All!
I have recently acquired 1980 Cherubini 33 who went through different owners.
There are two white hoses seen at the aft side of the bilge.

Wondering if they are related to these two thru holes on the starboard side. They are currently unused and plugged with wooden plugs.

Thank you in advance,
Herman

Press an air horn up against the external vent hole and see which hose it comes from inside the bilge.

OR

Run some water into one of the hoses inside the bilge and see which vent line it exits from outside the hull.

Are there any bilge pumps in the bilge? Are there hoses attached to the pumps?

I like @Ralph Johnstone‘s suggestion to pour a little water in the vents or an air horn or something to see if thst is where these hoses go.

Those hoses look like bilge pump hoses or old sanitation hoses. Run water through the hose from outside in and see where it comes out.

Those are thin corrugated hoses which haven't been recommended for use on boats in more than 30 years, although you'll still see them in use with bilge pumps. Based on the dirt on the inside of 'em, I'm guessing that's what they are/were The diameter looks a bit too large to be vent hoses...the thru-hulls you circled look like standard 5/8" vents...they're high enough on the hull and the right size. So I'm guessing again that one is for the water tank, the other is for the holding tank. You'll want to use sanitation hose for both. Shields or Trident flexible PVC #148 (cheapest) is ok for vent lines and toilet intake lines.

I can't pour water or honk a horn from the outside because one hole doesn't have anything connected to it, blocked by a wooden plug, and I can't see any hose in proximity. And the other hole has a short hose ending up under the sink in the head, also blocked by a plug.

There is a bilge pump with a hose going through the port side. I think, it was installed by one of the owners.
But I want to install a second pump and use an existing hose if possible.

it looks like you need to run new hose for your new bilge pump. Those hoses are shot and apparently not connected to anything.

Peggie, thank you for your detailed reply.
Water tank is at the bow under the birth and I believe it is factory installation. Its ventilation is also at the bow.
The holding tank vent is just behind those two that I circled. You can see a metal clamshell on the picture.

In my ‘82 H30, one of those original hoses was for a bilge pump and the other is the drain from the ice box.

I had the same style and what appears to be the same size hose connected to a manual bilge pump

Thank you! It helps.

In my boat there is a manual bilge pump mounted to the bottom side of the bilge cover, but it's not connected to anything. So far I couldn't figure out how to use it.

Thank you All for your help! Great forum here.

Unless you routinely bury the bow, on a long tack, a clamshell on the holding tank vent is a bad idea because it prevents the tank vent from exchanging the gasses in the tank with fresh air. I have recommended installing a clamshell backward (open at the forward end) to act as an air scoop, but only on boats that don't heel enough to bury that vent thru-hull.

YES.

Ice box drain & bile pump. The big pump exits the boat on the starboard side
just below the bathroom/head window.

There are two thru hulls in that location.

Bilge pump (the more forward) of the two
Shower sump (the more aft of the two)

Wow, Dumb-A spelling on my part. Sorry. New PC and not used to small keyboard

I have had the 1982 Hunter 33 for over 25 years.
Been in very nook and cranny so feel free to ask anything...

Oh, I didn't know there was a shower sump. On mine water from shower goes into the molded tub in front of the engine and then to the bilge. I was thinking of putting a sump pump for the shower, but to make a loop all the way up to the deck and throw water into the exit of the sink, which is below waterline, to avoid making bubbles with soapy water in a marina. People might not like it. Any danger in it?
