Glassy seas at Strumble and plenty of Porps

On an extended 2 hour Seasafari trip yesterday, we / a Swiss family visiting were treated to lots of Porpoise action on the landward side of Strumble bank! Probably in excess of 10 animals breaching towards the bank, observed over slack water..... We sat and watched from a distance, engine off.... until another boat approached at speed, whereupon they stopped showing. The waters (as well as being glassy) are very clear again, and are absolutely jam packed full of Jellyfish..... the year for a Leatherback sighting?
