The Maine Cat 30 is a yacht which very simply has less drag built with 100% Core-Cell composite construction and these features:

  • Low profile styling and aerodynamic rounding of all topside surfaces present a "slippery" shape to the apparent wind. Looks sexy too!
  • 10:1 length to beam ratio on the hulls coupled with a minimum of wetted surface area developed through months of computer "tweaking."
  • High aspect ratio foils including a single daggerboard in the starboard hull and balanced underbody spade rudders.

The total sail area is 500 square feet and designed to be very easy for one person to handle. Our jib has a roller furling/reefing system standard and is also self-tacking. The fully battened main has single line reefing a couple of steps from the helm and within the protected bridgedeck area.

Our Bruce Number is 1.31 when the "30" is kept light and delivers some sparkling performance sure to get the adrenaline flowing.

We install twin Yamaha 9.9 horsepower long-shaft engines with hydraulic power trim and lift—quiet power with superb maneuverability.

Stability and Absence of Heeling

The Maine Cat's stability and absence of heeling provide unparalleled comfort and safety. The wide beam develops a powerful righting force which keeps Maine Cats sailing level and dampens any tendency to roll or yaw in cross or quartering seas. The bridgedeck clearance is generous when fully loaded and slamming in short seas has been virtually eliminated.


A Maine Cat is unsinkable. Three large watertight compartments coupled with the foam core construction provide over 11,000 pounds of reserve buoyancy. Our hull shape has excellent seakeeping qualities.
