Fast Track Sailing Courses are intensive sessions designed to teach you the skills required for a Dinghy Junior rating. The Fast Tracks typically consist of 5 consecutive evenings (usually 5-8pm) of sailing lessons, running from Monday to Friday nights, with one-on-two instruction. As in other sports, intensive instruction will improve your skills rapidly. You'll be on the water for over two hours each session, have a debrief with your instructor afterwards, sharing food and drinks.
