Mark Chisnell divides his time between professional sailing and writing, and has won awards as a broadcaster and for his non-fiction accounts of maritime adventure. Mark began his writing career with sailing - the sport in which he won three World Championships, and subsequently won plaudits and recognition for his adrenaline-fuelled and suspenseful accounts of round-the-world racing.
"This is a book for all keelboat owners, whether racing or cruising. On-board instruments present modern sailors with a wealth of information such as: apparent and true wind speed; boat speed; speed over the ground (SOG) and velocity made good (VMG). And these are just a few functions. With all the info available it's really a case of understanding what they all mean, and how to use them. Chisnell answers these questions and turns on-board racing information into results with an expert guide on how to turn the theory into practice.'" (Sailing Magazine)
