Our first offering is the PT-11, a hi-performance 11 meter trimaran designed and built as a sport cruiser for a very discerning client.

Conceptualized in the fall and winter of 2009, the PT-11 was built as a prototype in 2010 and launched for the late summer season. In sea trials and subsequent sailing the PT-11 performed extraordinarily as both a performance boat and as a cruising platform. Some minor modifications have been made and the PT-11 is now available as a semi-custom series built boat.

Each PT-11 is unique as you want it to be. Thanks to the hi-tech construction techniques and materials used in building the PT-11 owners can add systems such as refrigeration, heat, and water making without over loading her. The PT-11 can be configured with the amas and akas demountable for shipping. Or in its standard non de-mountable configuration with fixed amas and akas. Exterior and interior finishes are all at the discretion of the owner.

Standard and non optional features on each and every offering from Performance Multihulls are quality, performance, and customer satisfaction.

Call, e-mail, or visit our Facebook Page today for more information and to set up an appointment to see and or sail the PT-11.
