[Ian McColgin]

Is "trimminoggy" related to the term "timinongy" (spelling suspect) which is the term for any line rigged across something to keep other lines from foulings? The most common example of that, though modern sailors don't often know the name, is when you rig a timinongy from the mast, perhaps about gooseneck height, down to somewhere on the foredeck to keep the jib sheets from fouling a hatch cover or bow cleat or whatever.

I always fancied the word was the nautical precursor of the land word "thingamjig."

G'luck
