Trimaran hull and boat

1. A trimaran boat, comprising:

a pair of sidehulls;

a center hull positioned between the pair of sidehulls;

a deck extending substantially continuous from one sidehull across the center hull to the other sidehull; and

a pair of center hull transitions and a pair of sidehull transitions;

wherein the pair of sidehulls each have a length between about 35% and about 45% of a length of the center hull, a transom of each sidehull is generally flush with a transom of the center hull, a design water line length of the boat is about 36 to about 38 feet, a beam of the boat is about 15 feet, the center hull has a beam width of about 3.5 feet, and a centerline of each sidehull is about 7 feet from a centerline of the center hull;

wherein the boat has optimum energy efficiency at speed between 14 and 20 knots.

2. A trimaran boat, comprising:

a pair of sidehulls each having a v-shaped transom;

a center hull positioned between the pair of sidehulls;

a deck extending substantially continuous from one sidehull across the center hull to the other sidehull; and

a pair of center hull transitions and a pair of sidehull transitions;

wherein the pair of sidehulls each have a length between about 35% and about 45% of a length of the center hull; and

wherein the boat has optimum energy efficiency within a predetermined cruising speed range.

3. The trimaran boat of claim 2 , wherein a transom of each sidehull is generally flush with a transom of the center hull.

4. The trimaran boat of claim 2 , wherein the deck is configured to store a plurality of lobster pots.

5. The trimaran boat of claim 2 , wherein operating at about 16 knots the boat has about a 20% lower power requirement than a comparable monohull boat.

6. The trimaran boat of claim 2 , wherein a design water line length of the boat is about 36 to about 38 feet.

7. The trimaran boat of claim 2 , wherein the center hull has a beam width of about 3.5 feet.

8. The trimaran boat of claim 2 , wherein a centerline of each sidehull is about 7 feet from a centerline of the center hull.

9. The trimaran boat of claim 2 , wherein a beam of the boat is about 15 feet.

10. The trimaran boat of claim 2 , wherein an engine is positioned in the center hull.

11. The trimaran boat of claim 2 , wherein the center hull has a keel and a draft of about 4 feet and 1 in.

12. The trimaran boat of claim 2 , wherein the boat has about a 100 horsepower engine and with a displacement of about 12,000 lbs and a propeller efficiency of 65%, the boat consumes about 5.3 gallons per hour of fuel or less operating at about 16 knots.

13. The boat hull of claim 2 , wherein the boat has about a 200 horsepower engine and with a displacement of about 12,000 lbs and a propeller efficiency of 65%, the boat consumes about 10.3 gallons per hour of fuel operating at about 20 knots.

14. A boat hull comprising:

a pair of sidehulls;

a center hull positioned between the pair of sidehulls; and

a deck extending substantially continuous from one sidehull across the center hull to the other sidehull;

a pair of center hull transitions and a pair of sidehull transitions;

wherein a transom of each sidehull is v-shaped and each sidehull includes a chine between the deck and the waterline that extends a length of the sidehull, the chine runs down toward the waterline moving toward a stern of the boat;

wherein the boat has optimum energy efficiency within a predetermined cruising speed range.

15. The boat hull of claim 14 , wherein the pair of sidehulls each have a length less than half a length of the center hull and are positioned outboard and aft at each side of the hull such that the transom of the sidehulls is generally aligned the transom of the center hull.

16. The trimaran boat of claim 14 , wherein operating between a speed-length ratio of about 2.67 to about 3.33 provides a maximum energy efficiency.

17. The boat hull of claim 14 , wherein operating between a Froude number of about 0.80 to about 1.00 minimizes the power requirement for the hull.

18. The boat hull of claim 14 , wherein the sidehulls are configured and positioned to cut through a bow wave created by the center hull, thereby reducing spray.

19. The boat hull of claim 14 , wherein the hull has a lower powering requirement than a comparable monohull boat experiencing the same conditions when it has a displacement of less than about 16,000 lbs and operating in a speed range of about 10 knots to about 20 knots.
