I'm the original owner.
My boom is one piece and the mast is hinged right at the fly bridge deck level. The boom connects to the mast just above that joint. I see your boom connects much higher on the mast. Probably a good idea as mine is a real head knocker where it's at. I used to lift mopeds aboard with the boom, but it doesn't get much use anymore. Since I moved to open moorage I haven't had to lower the mast, other than to inspect and replace the anchor light.
Glad to see you still have your tag. . . . Some don't!!
