A boom vang is a length-adjustable support that runs from lower on the mast to a point out on the boom. The ones I'm familiar with are hydraulically adjustable to support the boom and allow adjustments to the sail's shape.
The Nordy MS56 (muh dreamboat) uses a heavy Leisure Furl boom with the main furled in it. The vang is used to take the load off the cable (shroud?) out at the end, and this boom is also used to bring the dinghy up to the boat deck.
It needs a little help.

I read it is to be set 1.8 degrees below horizontal on those boats.
Pretty heavy unit, I guess.
