Slightly off topic,
Paid commercial Sydney Harbour Mooring, on more than 1 occasional the yacht next to me hits mine. Now hairline compression cracks in Gelcoat, and a few chips out.
I was on the way out to her once when I saw it happening. Generally on ebb/slack tide, low but some wind. Pushed them apart with my tender.
Is commercial mooring operator liable? I called him while it was happening and even took photos and video... his excuse was the mooring chain twisted?? Surely if he knows the boats length, he wouldn't put 2 yacht that could hit each other?
Not by a little, the other yachts beam hit my stern. The other stern was hitting my topside at my cockpit.
