Hmmm I'm sort of on the fence on this one which is unlike me as I'd normally slag yachties off.
I've had divers down and yachts, fishing boats and jet ski's getting a little bit too close for comfort, despite repeated blockings to get in the way of them and the divers and several heated discussions on the radio.
I've also been on a safety stop and had a yacht keel come flying out of no where and split four divers into two very nervous groups!
However I have been given the finger several times for motoring up (at full whack) through a "High Speed Craft Zone" from fishermen sat in the middle of the fairway.......which I consider to be their own stupid fault for being there in the first place.
If everyone behaved by the rules it would be a lot easier. But if the fisherman from Hannahs original post was on dry land, it was not restricted by speed limits in the area they were playing, they weren't endangering themselves or more importantly anyone else.....then I can't see a problem.
You don't go for a peaceful days fishing on a fast craft area and you don't get umpty when a fast boat utilises the area.
