As for maneuvering in tight quarters, until recently the twin engines of the catamarans had it hands-down over the single screws of the monos. Without touching the helm, the average cat can spin in its own length by using forward and reverse on the dual engine controls. However, the relatively high windage and lack of lateral resistance combine to create significant sideways slippage in windy conditions with most multihulls. On larger monohulls (and many smaller ones these days), bow thrusters have become nearly standard, and with the new integrated thruster and articulating saildrive systems gaining acceptance, the maneuverability gap has essentially been closed. Under power, it’s worth noting that catamarans have the advantage of redundancy with twin engines, especially if the systems share no common components. But, of course, that means twice the cost and time of maintenance.
