Obscure Trailer Question

Here’s a question that only FC owners would know: If you drop the mast, such that it’s attached to its foot but the rest is leaning on the gallows, what would the height be at the very top of the mast?

A measurement off the water would be great. But also, I’m thinking of loading on the trailer, where the height off the road would be important.

The answer is 9.5 feet from top end of mast to waterline when lowered on the crutch. Good to know for going under a low bridge. But for trailering, the mast would quiver too much and shake the gallows apart (probably).
