Tom Sowerby

Tom grew up around boats and started sailing when he was eight. He joined Bisham Abbey Sailing and Navigation School in 2002 and has won the RYA Inland Waterways Instructor of the Year for his coaching.

Bisham Abbey Sailing and Navigation School is based within Bisham Abbey National Sports Centre, located on the banks of the River Thames just outside Marlow in Buckinghamshire. Tom is the School Principal.

Part 1 - Sail Trim

A brief look at how a sail actually works and why correct sail trim is important. We’ll discuss the basic aerodynamic theory and how you can ‘see’ the air flow over your sail thus making sure you’re getting the most from your boat.

Part 2 - Passage Planning

Why? When? How? A discussion on the importance of doing a thorough passage plan, how to get started and make sure your planning is efficient and accurate. We’ll also look at the steps to go through from your first thoughts on planning a trip to successful execution of that plan.
