 However, unlike a monohull, a multihull has a "point of no return" which will lead to the vessel becoming inverted.A catamaran dinghy may be righted by its crew, but a large cruising cat will normally remain inverted unless it can be craned upright.A catamaran that is being pressed too hard may "pitchhole (capsize)", a disastrous event whereby the lee bow (downwind bow) digs into the water and trips, followed by the stern rising and the entire vessel somersaulting.
