The first edition (0953195619 which went out of print Spring 2007) rapidly became a standard text for sea kayakers. This new edition builds on that success. There are numerous improvements in the explanations and GPS is covered in more detail, reflecting the increased availability and usage of electronic navigational aids. Full use is made of colour photos, diagrams, maps and charts, further enhancing the reader's experience. Exercises to reinforce and self-assess how much the reader has taken on board are provided at the end of each chapter. Sea Kayak Navigation is recommended as support material for the new British Canoe Union navigation courses that are currently being introduced.
