Description A modestly sized, affordable cruiser, the Quest 31 was one of the first Prout catamarans offering comfortable, safe ocean-going capabilities. Ideal for families on a budget, she provides ample interior space for live-aboards or extended cruising, is easy to handle by even one person, and has an impeccable safety record. She incorporates the proven Prout design features of U-shaped hulls with low aspect ratio keels, central nacelle, large working genoa and small, manageable mainsail. The result is a relatively fast, easily sailed, dependable craft that even novices can be comfortable sailing.
