thats awsome... we were looking for those all day sunday. our water was nowhere near as calm. even though they said 2-3's, it was really 3's with the occasional 4-5.
makes for an interesting day in a 18ft boat. it was fine because they were far enough apart, but i sure would have liked your seas and sights.
we did come across a relativly large dorsal fin with a smaller tail.
I say basking shark... my g/f says jaws.
where were you?
