Lagoon 450s Owners Version General Information

Susan Ann II a Lagoon 450s catamaran sailing yacht was built in 2017, she is a fully equipped around the world sailboat for a luxury liveaboard life. The 450S is the perfect yacht for the cruising couple or family and combines safety, comfort, and speed at an affordable price.

Susan Ann II can accommodate 8 passengers in 3 double cabins featuring 3 heads with electric toilets. Living areas are large and allow plenty of light through the wide straight-up window design.

Her sailing characteristics will pleasantly suprise her new owner under all conditions. The lower boom design brings the center of gravity lower and reduces inertia in the rig compared to the fly bridge alternative. On  reach and beam reach she sails superbly managing 10-11 knots  at 6-8 ft. seas with little or no slamming.

She is superbly built and you will not find much fault when it comes to built quality. Deck surfaces are flat and even, the hull is vacuum infused, a process that ensures the optimum laminate/resin ratio which reduces weight significantly. Less weight allows for more volume in catamarans. Rudder tube is composite and laminated into a solid section of the hull towards the stern. The semi-raised helm station is designed to integrate with the whole design of the boat and is pleasing to the eye. It is well laid out, comfortable, safe and big enough for two or three people. One has good accessibility to both the cockpit and coachroof from the helm with sturdy, solid stairs from the cockpit to the helm and up to the coachroof. The helm station also has plenty of handholds and places to wedge oneself to work the winches.

Susan Ann II is a really good, comfortable liveaboard bluewater cruiser, her new owner will be pleasantly surprised as her sailing ability and comfort at sea are best in class. The Lagoon 450S is a great live-aboard boat! It is fast, safe, and has enough living space to be comfortable.
