Ocean Discoverability®
Our rather unique Ocean Discoverability day sails support many young people each year, including those with life-limiting conditions, from additional needs schools and units, and day centres in Plymouth, Devon and Cornwall. This work expands on our own day sail provision which is open to all, and is in addition to our residential sailing voyages.
Ocean Discoverability is our evolution of the work of Cornubia under the Bristol Channel Pilot Cutter Trust from 2010 to 2016. Cornubia’s first mate, John Hepburn, joined our team in 2017 to run our own programme, ensuring a quality and enjoyable educational experience from day one. Together with John, we continue to seek major and supplementary funding to help support our delivery of this much admired service.
What we do on an Ocean Discoverability day sail
On a typical day the young crew will observe, touch and feel marine life in the marina before examining it under the microscope and via an underwater camera on the seabed. After a safety brief and boat familiarisation the sea trip begins, by gently motoring down the River Plym to Plymouth Sound while stowing the ropes and fenders. This helps the young crew get used to the boat and its motion. Once in the Sound, those who wish to do so will help hoist the sails and steer. There they gain an appreciation of the geography, the marine life and other ships and boats, spotting and recording them in their personal guidebook.
Depending on the levels of ability there are:
- mystery objects to find on deck;
- simple tasks like finding and counting all the stanchions;
- a nautical word search;
- calculating the boat’s sail area and learning some knots.
While some just enjoy the sensory experience. On the return journey they help collect samples of plankton for microscopic examination when back in the marina.
This great experience for additional needs schools and day centres, adds to the range of what we can offer to young people giving them the opportunity to enjoy time on the water, expand their skills and explore all the other benefits of sailing.

John Hepburn
This is my tenth year with The Island Trust. My role is to raise the funds and help develop and deliver the Ocean Discoverability day trips – during the six years prior to this I worked doing the same trips in the Bristol Channel Pilot Cutter Cornubia. I started sailing when I was 14 and in my early 20s I was a volunteer mate in the Ocean Youth Club, sailing gaff and bermudan rigged boats. Then throughout my 30 years in the Navy I carried on sailing in my own and other people’s boats. From that time on, I have worked with several organisations helping to raise awareness of the sea, the amazing things that live in it, the amazing opportunities it offers and why our ocean is so important to us all.
