As reported to David Remsen from Capt. Dan Sullivan. The Gemma came across a Grampus while collecting squid in Menemsha Bight. First observed 50m from stern jumping clear of the water twice. Approached the Gemma, which was idling while clearing the net. Approached the Gemma and fed on discarded by-catch (fish). Stayed very near the boat for 10-15 minutes before the Gemma departed.
