Another game of "What is it."

[OldFrog75]

Is it on the transom?

[cwyckham]

Looks like an older boat if the deck scupper drain is brass. Has it been rigged for cruising? If so, I'm also going to vote for an attachment to catch rainwater off the decks. You let it rain for a while to clean off the salt, then catch the water and put it in the tanks or jugs. If you don't want to drink it, you can at least use it for laundry and showers.

Actually I think the OP just stuck that on there to see how much milage he could get out of the CF group.

[GeoPowers]

Or, instead of a bucket-catchment (assuming this is a deck scupper), perhaps it is to block the flow of water. Maybe there's a piece that slides through the base of the white half moon and goes up flush with the drain so that the whole deck can be used to catch water. Tough to say without some more info and preferably more pictures.

[Wotname]

What does the previous owner say about it?

[HBWT]

Maybe a catch basin but I can think of several beter ideas thas mounting this huge piece of plastic to the side of the hull. Hit something and this thing is going to take alot of fiberglass with it.

I was hoping it was some sort of cool cruising accessory but this boat needs alot of TLC and cruising setup as not been updated since the early 80's. Oh, well.

You ask for a better picture back a little ways and this is the best I have. WAY BACK! You can see it just aft of the bouy. If it was a boarding ladder mount, why woudnt they mount this under the gate opening off the lifelines. If it was a water catch, it could be far better and simpler to rig something off the stantions.

Is there another one portside? It does appear to be specifically mounted under the drain, and too low to the water for holding a bucket. It is close enough to the waterline to be underwater on port tack if the boat heels much at all. Could it be a place to hook the dinghy to the boat somehow? Why can't the broker ask the seller?

[autumnbreeze27]

There's got to be something on the boat that fits in that spot.

Maybe the gate used to above this object and has since been moved forward?????

[senormechanico]

What's on the other side of the hull?
Gotta be the galley, or an aft cabin sink?

[HBWT]

Yes, identical placement and mount on the port side. The PO is no longer available to ask and the broker has no idea. Another idea I had was maybe a boom mount for a flopper stopper, a emergency boarding ladder mount, a clip in swim step, something that makes sense. But nothing on the boat fits this configuaration.

[HBWT]

Other side of the hull is a 75 Gallon Fuel Tank Starboard and with 75 Gallon fuel tank Port. The thru hole is from the deck wash grate scupper that butts up against cockpit step.

I see my powers to stump the CF community is strong. I know the simplest answer must be the right one but I am afraid that this is probably one of those cases where the PO observed something at department store display and thought, "wow that floating attachable beer cooler would look great on the side of my boat."

And so the battle begins.

[delmarrey]

Your fuel fill fitting wouldn't happen to be in the cockpit?
I've seen jury rigged drain catches on a Coronado that had its fuel fill in the cockpit.

[HBWT]

Oh, that could be it. Just aft of the infamous deck scupper.

[Wonderinlost]

Thanks for a wider shot.

My same thoughts. I'd say some kind of catcher mount. Maybe previous owner used real harsh no good chemicals many times cleaning the cockpit or if fuel was transferred on deck at all. Where is the boat? Could the boat be or spent a lot of time in a strict environmental regulated area?

There's no bracket to keep it from popping up how it appears. I don't know how well of a flopper stopper it could be. Neat idea to mount. I'd be afraid that would be some horrible torque to put on such a small are for relentless flopping.

wondering around with no destionation
