Hawsepipe vent/cowl?

I was wondering if while in my slip or on a mooring I could add some ventilation to my anchor locker by getting some air down the hawsepipe?

The locker has a louvered wood door, but I really don’t think any air moves in or out. Would be nice to air it out after using the anchor, I don’t have enough deck space to reliably dry the rhode every time.

Hawsepipe is a spartan bronze oval tube.

Anyone done something like that?

If I was thinking about that I would want the air from inside the boat to go over the smell of the anchor locker and then out the hawsepipe.

To do that you may need to rig a fan that draws air through your louvered wood door. It could be done with a computer fan. Would not need to be much. The fans are quiet and use little DC power. You could use the electrical light connection in the V-Berth to power the unit and a switch to turn it on when desired. Additionally you could wire a timed switch to turn the fan off when not needed or when forgotten.

I have a cowl vent mounted on a dorade box, directly over the anchor locker. The anchor locker is open to the veeberth. I installed it for the reasons you mention, plus a couple more: I needed an access to a deck wash that I also installed in the anchor locker.

That access is through a clear deck plate in the dorade box and the nozzle hangs just below.

The clear plate was chosen as the locker was dark. The result is a passive and powerful (or a mooring) air flow into the anchor locker and through the boat and a 'light' in the locker. It does a great job drying out the rope and chain rode. That keeps it odor free.

The forward cowl joins 2 other 4" cowls that fill the boat with fresh air that flows through the boat and exhaust out 2 aft facing cowls, one past the engine compartment to ventilate that.

If you could fit a cowl up there, even without a dorade box, you could swing it forward in good weather but turn it aft when leaving the boat to keep rain out. There's no comparison to the flow of a cowl vs. any typical mechanical deck fan. Plus it's a simple passive device.

Just to be a curmudgeon here, but a hawse pipe is set on the side of the hull. What we are discussing here is a deck pipe :)
I thought it was a spurling pipe.:):)

We have a short cowl vent mounted on ours that the anchor line simply runs through. Under way we turn it aft, so it doesn't direct water below. At anchor we turn it forward - like TomY's - to bring air through the boat. If we really expect to be taking green water over the bow, we have a deck plate that can replace the vent.

I was hoping to find a solution like this- but my deck pipe (thanks for the correction Charlie) is this one https://www.spartanmarine.com/all-products/hwyklhu0dx295xb8fvm14qrjeme0n7
Would love to find a little cowl vent to fit that, but pretty sure I’d have to have one made.

It would be easier to install something like what we have: Low Profile Stainless Cowl Vent, White / Dorade Set
Our anchor line simply comes up through the vent from the locker below. Our vent is PVC, not stainless.
