Marine Discovery

Marine Discovery runs wildlife-watching sailing trips from Penzance Harbour on the catamaran Shearwater II. The operator is based at Albert Pier and focuses its trips on Mounts Bay and the West Cornwall coast, where the crew may encounter grey seals, seabirds, dolphins and porpoises. The point is observation rather than a guaranteed checklist: conditions and wildlife activity determine what is seen on a given day.

Trip length is worth choosing deliberately. Visit Cornwall lists a two-hour Bay Discovery for the inner bay, a three-hour Ocean Discovery and a four-hour Discovery Voyage for people wanting more time on the water. The longer options suit visitors who can spare the time and are comfortable at sea, while the shorter trip is the more practical starting point for families or anyone fitting a boat outing around a wider Penzance day.

Booking should begin with the current departure details, weather policy and the needs of everyone travelling. Bring layers, sun protection and anything you normally need for motion sickness, then allow time to reach Albert Pier without rushing. Marine Discovery says it also records scientific data during trips, so the experience is as much about understanding the marine environment around Mounts Bay as looking for a particular animal.
