Tartan 30 Bayfield, WI
I purchased my 1977 Tartan 30 2 years ago and still am sorting through all the misc parts that came with the boat (having a great time doing so I might add). It came with a spinnaker and most of the parts to hoist and control it. In the bag that housed all the spinnaker rigging, there were these 2 gems that I have not been able to identify. There are 4 pcs, however they were screwed together. All of the pieces are knurled and there are rubber washers on all 4 pcs. They screw together like a lip balm container. I have looked all over the boat for a hole that needs filling and/or needs capping but no luck. They could be just parts that the PO had on the boat.
Any ideas:

Thanks for the help as always,

Here's my thought. And normally you would get a joking reply from me but not this time. They appear to be brass ends that, in use, don't screw together. They are screwed together now for storage but would normally go on opposite ends of some sort of tubing or piping. I'm thinking a gas line. Thus, the rubber gasket.

Or they could be snuff containers. (Dangit! I just couldn't do it!)

p.s. The other thing is a tape measure.

Yeah... They do look like hydraulic caps. Hmmm... Don't know what they are doing on my boat, I guess the previous owner removed the Hydraulic Halyard system before selling it ;)

Thanks for the info.

there were several boxes of stuff with our boat also, when we purchased it... lots of stuff, but not all of it was boat related.

But I do agree with rgranger too.... throw them away or leave them home when you are off on an extended and remote cruise, and you will find out exactly what they are supposed to go to.:biggrin:

The PO found them on the boat. Didn't know what/if the PPO used them for, so kept them JIC. Passed the legacy on to you.

Hose caps that cap garden hose ends. I use these to cap short hose which is needed to put oil onto the motor because overhead clearance is just 6 inches. The caps prevent residual oil from leaking out of the hose when it is coiled and stored.

Caps for the propane tank and connecting line

I agree. They look like propane bottle caps. PO might have had a Magma gas grill on board and used them to cap off the 1 lb. propane bottles that weren't being used.

You will search in vain for any thread match except garden hose thread called GHT , non taperd , 11.5 TPI

I just love a good old-fashioned argumentative thread!

you are correct in this statement about hose bibb threads, but these threads are finer than that, and the seals on the female plug are in the wrong spot.... and its hard to account for the different sizes shown.... hose bibb fittings are only available in one size... which also would rule out the propane cap theory.

does the boat have a hydraulic autopilot, or windlass.... I suspect Jackdaw is correct, that someone had them with the boating gear for some reason, and none of the past owners could figure them out, but didnt want to throw them away, so they have been passed along with the boat...

they are clearly not bronze, brass or plastic, but steel... so probably not marine related.
