The mast being moved further aft offers many advantages on a cruising catamaran:a self-tacking genoa for ease of use,
– a larger foretriangle for a greater choice of downwind sails,
– a shorter boom for ease of manoeuvring,
– a mainsail that is broader near the head, taking advantage of less turbulent wind for a real improvement in performance,
– re-centring of the weight, which greatly reduces pitching.
