Click here for Catamaran Designs Over 30ft (8 designs)
The over 30ft range of designs comprise both open and bridge deck cabin boats.
The range of designs comprise a wide variety of open deck and bridgedeck boats. These boats have added load carrying and increased seakindliness compared to smaller designs so are more suited for offshore sailing.
We do not recommend home builders to attempt a boat over 40 ft unless experienced and want a boat for charter or long term cruising. Most families will find that boats under 40 ft will comfortably meet their needs.
