Not sure what these are

[JakeB]

Recently purchased a Phantom 30 and found these in the gear locker. They don't weigh much, but my first thought was something for keeping pylon lines from getting tangled. Seem to be made out of grey plastic, pvc or similar with welded SS rings. They are closed on each end, not hollow. Anyone have the real story? Thanks in advance

Maybe some sort of pin, lifting rudder or centerboard or belaying pin?

Probably not what they are, but I have seen and used steel pins for certain types of marine railway haulout supports. The pins hold the arms of the supports in the right positions to keep the boat upright on the marine railway.

I await a solution with bated breath

My guess is they're toggles to slip though the spliced loop of a dockline after feeding it though a hawsehole, or to secure a dockline to a ring on a wharf or pier.
Rings on wharves, meant to be secured by such a toggle are a pretty common Scandinavian setup.

This seems likely. I have seen those rings and wondered about the best way to secure to them. Will look for these in play, next time i'm at a wharf that uses rings. Thanks for the reply.

This could be. The haulout here though, is a remote controlled low slung strap lift, called a sub lift. But maybe these are legacy from a previous yard.

Lol.




Very interesting possible use i.e. toggles. I have never thought of tying off to a ring bolt on a dock like that. Presumably you could then do your preferred cleat finish on the toggle, if it is long enough. I look forward to trying it out this summer.

Most travel lifts have a hoisting strap that can opened in the middle. They get tied together using just such a device, though the one's I've seen were made from metal

Could they be emergency plugs for a failed seacock?

There's no cleat-hitch required: you just slip the eye of the line through the ring, insert the toggle crosswise, and Bob's your uncle. The toggle can't get past the ring against which the line is holding it. It can't slip out easily if it's loaded, and is unlikely to when unloaded, unless someone kicks it or something.

If that was the case ( dock line support) one would think you'd see some " wear" marks on the toggle, where they would butt up to the dock cleat or ring, and they are also likely to move as a boat rises and fall, but they look as pristine as a baby's bottom....

I can't say for sure, but they appear to be made from wood, not a good material for a dockline doodad as the wear and tear on a wood toggle would promote a short lifespan.

I don't recognize those, but I bet you are right. Makes it easy when leaving to just pull a line attached to the toggle, like a dog bone, pull it out of the loop and you're free. You don't need to get off the boat.

BTW Jake, how many do you have? I see another in the alcove there.
