Can anyone identify this hose ?

I found this hose under the dinette in the same compartment that has my black water holding tank for the forward head (port side).

This hose passes through the compartment and is not part of plumbing for the forward head.

This hose passes under the dinette floor and appears to go into the same compartment as the salong AC unit underneath the forward dinette seat. However, looking in the AC compartment I cannot find this hose, so I assume that it must be under the floor supporting the AC.

Following the hose aft, it passes through the bulkhead and passes into the engine compartment (again port side).

I was unable to easily ID in the engine compartment from the center hatchway - and the Admiral has her couch over the top of the port engine hatchway.

I can move the furniture around and gain access to chase it further - was hoping that someone would know what it was for

There's only a few things that one would use that type of hose for;
- bilge blower
- HVAC (AC and heat) though it's best to have the insulated type
- exhaust venting for the head
- Exhaust venting for the galley
- washer/dryer venting
- windshield defrost venting, etc.

It is the exhaust vent hose for the fwd head. There should be another compartment just to the port side of that compartment and there should be a rectangular access hatch under the cushion. You'll see that hose enter that compartment, then turn aft and go through the main bulkhead. Right behind that bulkhead would be the head exhaust fan. You can access it by the cubbyholes on the port side of the salon. There's a shelf in there that has to be removed, then there are two panels, each held in by four screws (one in each corner).

The aft cubbyhole has the same setup and in there you'll find the vent fan for the aft head.
