Most peculiar, that a tow boat would take you into a yard without calling in ahead to see if they would receive it. Without knowing that a local yard didn't take in certain types of vessels.
Especially since the marina is listed as a boat-us cooperating marina and the base for a towboat-us operator, who presumably would know what his home yard would or wouldn't take in. A yard that advertises as doing sailboat rigging, and having 24x7 diver and mechanic services, so replacing a prop nut is a fast easy profit.
A cynic might think this was just a slam on a marina from a new troll.
