What is This?

This spring I purchased my well equipped Vancouver 27. I have been away from sailing for a few years (30+), so it has taken most of the summer to figure things out. However I am at a loss what this tool/adapter is for. The boat has Harken 44, 32, and 16 winches and a winch handle does fit. Also a Lewmar windlass.

Re: What is This?

If what's on the back it fits in a winch, it is probably a gear reduction system, adding a second cranking speed.

Or a ratchet.... Odd, though. Never seen one of those before but definitely winch handle oriented.

Re: What is This?

Although it fit a winch ratchet it does not fit on a winch. It is definitely some type of reducer. I have not yet serviced the winches. Thought it could be a tool for doing so? The boat has a 2GM20F Yanmar. Though it could be some sort of hand cranking tool, but no. Backside picture attached

Re: What is This?

The back side spline looks like it would fit a gearbox input shaft spline or something similar.. allowing you to use a winch handle to rotate whatever it fits in/on?? Directly or with some extra mechanical advantage depending which drive you plug into. Windlass maybe??

No connection point on my Lewmar windlass. I think it has to do with the Harken winches. However I cannot see the need for further reduction as the winches are really oversized for the boat and there is no male connection point. I have heard of sites that can match pictures. May try that.

Re: What is This?

There may be a splined shaft internally in the winch - this would allow you to turn that during overhaul?? Reaching now..

I think one such site (picture search/match) is called 'tinyeye'

Re: What is This?

My guess: engine hand crank adapter for
winch handle.

Only problem there is that every hand crank mechanism I've seen has a 'kick-out' feature.. ie if the engine starts turning itself it tends to kick the starter handle free rather than take the cranker for a nasty ride.

Add to that that few, if any, engines have an exposed spline shaft makes this unlikely...

But someone went to some trouble to produce it, so it must have a purpose...
