How stoopid can they be? If they cut any wire on my boat I'd be slapping them with a bill for an AYBC electrician plus repair of any other damage they cost. jeez!
No kidding! If the yard workers cut the wires, they ought to be held accountable!
Funny the terminology "demasting." To me that sounds too much like "dismasting" which is when your rig comes down when it's not supposed to.
We've had horrendous experiences with yard crews and masts. The first and only time we let the yard monkeys unstep our mast ended badly. My husband wanted to be there for the procedure, but arrived at the yard a few minutes late. The yard monkeys had neglected to attach the mast to the crane before they pulled the pins. CRASH! Mast went down onto the ground. Apparently the concept of a deck-stepped mast was foreign to them.
I give the yard credit for springing for a new mast and R/F unit, but my husband put ALL the mast fittings on himself, just so it could be done right.
So the following spring, it came time to step the mast. This time we got there on time. Good thing we did, because the yard monkeys were having trouble fitting the cables into the bottom of the mast and got their wire cutters out. My husband saw what was going on and (fortunately) got to them before they could cut anything, and he stuffed the wires up into the hole at the bottom of the mast. Yes it was tight, but it was doable.
For these and other reasons, I do not consider "yard maintained" to be a good selling point when I look at ads for boats.
