Hope the "Doc" is feeling better and recovers soon.
Good on the rest of the locals for looking out for him and his gear. Another case of wishing you had eyes in the back of your head.
One of my local fellow sailboarders (also a Doctor) got run over by a large power boat last year in Gosford. The idiot skipper did not stop to see if he was alright and just kept going to his mooring. Luckily the doc got back in even with a damaged sail and board, he phoned the local police who got the Water Police to come out and take a statement. They then found and interviewed the boat skipper who said he did not see the sailboard till it was too late to turn but thought the sailboarder was OK because he surfaced. (What an excuse!)
Boat skipper was charged with negligent driving, was heavily fined and had to pay for the replacement board, sail and boom. Many $$$.
Doc was very lucky indeed. He expected the boat to give way but when they aren't looking where they are going it can lead to a serious accident.
