Hi Spyro, we (Webcraft + swmbo + me on Amaranthe) saw one just like that last Saturday heading north up the Sound of Bute- Webcraft said it was a basking shark, as well.

Artificial Intelligence is no match for Natural Stupidity
I've seen basking sharks before this one seemed to be different in the way it moved and turned very quickly This one was spotted just inside the north channel between Holy isle and Arran.
Like yourself, we're fairly familiar with seeing the occasional basking shark, usually on their own, pretty big (4-6m?), fairly slow moving, and not in the least interested in the boat. However last year, off the Treshnish Isles, we came across a group (pack/pod/warren?) of 6 or 7 sharks behaving oddly. Like yours, they turned erratically, were fast (perhaps 6/7 knots), and were smaller, about 2-3m in length. They were also interested in the boat, and would come straight towards us and then sheer off at speed.
The people at the wildlife centre at Tobermory suggested, like Neraida and Cliff, that they may have been porbeagles. Unfortunately, the photographs were taken pointing towards the sun, so it is not possible to identify the distinctive white marking on the rear of the (porbeagle) dorsal fins.
We could not see the snouts or their jaws, and in all other respects the dorsal fin looked like those of basking sharks. So, if they weren't porbeagles, then perhaps the only other explanation is that they were basking sharks behaving badly.
