Been away from my computer for a while. Seems this has generated a bit of interest.
Firstly, the point of starting the thread was not to "name and shame" people or to point angry fingers, rather to just highlight the cautions we should all take in areas particularly known for wildlife, like the Rummell Stone. Last year, I almost ran over a sunfish in Plymouth Sound so "there butfor the grace of God etc."
The boat in question seemed to be observing the animals rather than on the A to B and seemed to get too close. It wasn't you Dunc. Your outfit has a great reputation and your jet rib is pretty recognisable!!
Since getting my boat, the best experiences I have had have been encounters with wildlife and its a subject close to my heart. We've just all got to be more careful.
By the way, Dunc, love your plastic bag retrieval idea on your website. Now plastic bags and fad butts. I feel another thread coming on!
