Inspiring sea safari sailing trips aboard a ten metre catamaran, with the winners of the 2013 Responsible World Whale Watch Awards . A voyage on "Shearwater II" gives you the best opportunity to find the marine wildlife of south west Cornwall, including seals, porpoises, seabirds, dolphins, basking sharks and whales. All trips are fully guided with experienced and entertaining guides, who are trained educators. Shearwater II takes just 12 passengers and 2 crew, so you get a great view of the wildlife and the views without having to peer over other people. Please call or email to enquire.

Fully licenced and insured

NB please remember that sightings of specific species cannot be guaranteed and that we advertise this fact widely. Therefore the most useful and accurate reviews of our company rate us on the factors we can directly control e.g. customer service, politeness, ease of booking, quality of welcome and so on, rather than whether the reviewer saw the exact species they wanted. Marine Discovery is shut between November and March due to weather constraints and winter maintenance. If in doubt, call to check.

Went on the 3 hour trip and it was brilliant. We saw dolphins, seals and lots of birds. Being on the catamaran was exciting itself and also very relaxing, especially as you could lie on the large area of netting at the front of the boat so that you were directly above the sea if you wanted. The skipper and... More

After two failed attempts to see dolphins on our holiday in Cornwall, we decided at the last minute to go on the Marine Discovery trip from Penzance. There was a slim chance it was going to be cancelled due to lightning being forecast, but the person I spoke to explained when they would make the final decision. Luckily, the trip... More

Recently enjoyed an amazing 3 hour trip with Marine Discovery in which we were lucky enough to see dolphins and have the privilege of having them bow riding for some of our journey. Seals and Sun Fish too, along with expert commentary from both Duncan & Tom. We were very lucky to see so much wildlife on our trip but... More

Enjoy boat trips as do our friends. However this was a little different. Weather great and sea quite calm. Unfortunately the Dolphins were hiding. We did see porpoises, seals and many birds but the thrill was also being on the catamaran. Good detailed history of shoreline locations including minack theatre and wildlife. Great three hour trip. Even though weather good... More

Fantastic, enjoyable and informative. Both Hannah and Duncan are passionate about the marine environment and very knowledgeable not just about the marine fauna and flora but of their local area. This was highlighted on the second day when the dolphins were not too keen to play and they kept us all informed about the many different sea birds present and... More

Had a great day on the marine discovery trip, the guides were friendly and knowledgeable. Unfortunately on the day we didn't see any Dolphins, sharks or whales but saw a variety of birds, jellyfish and some seals. Was great to get away from everything and set sail on the catamaran for hours enjoying the scenery.

This is our second trip with Marine Discovery. The last being over 2 years ago. A beautiful day to cruise along the South Cornish coast. The team are very knowledgeable about the area and the animals scene on our trip. Everything is recorded via GPS and photos to record sightings of Basking Sharks, dolphins, porpoises and seals. It's a great... More

We went out on the trip this afternoon & even though we weren't fortunate enough to see everything we still had an excellent trip. Hannah & Duncan are both very knowledgeable about the local area providing interesting information on local places. Would definitely recommend 👍

We booked a 3-hour trip last week which was originally postponed for weather reasons. Be prepared that this may happen - Mother Nature rules. Hannah kept us updated all the way and we finally got on board on a calm, sunny day. Loved just being out on the sea, so was open minded about what, if anything, we would see.... More
