The Patented Power Proa Hull Design
Catamarans offer a stable ride with predictable hull movement. The seakeeping is excellent, even in rough conditions. Another advantage the design provides: incredible onboard space. The space of a catamaran is often comparable to that of a monohull that is 25 percent longer. Catamarans also have been proven to provide efficient operation.
Power Catamarans: A Complete Guide
However, the power catamaran is a relatively modern innovation that marries the traditional twin-hull design with powerful engines, offering a unique blend of speed, stability, and space. Distinguishing Design: Power Catamarans are characterized by their twin hulls, which significantly reduce the drag, thus enhancing speed and fuel efficiency.

The power needed to do 30 knots is about (2) 450 hp or 900 hp. One live example of a displacement catamaran is the HoloHolo on Kauai. See www.holoholocharters.com Its 62' long, weighs about 25,000 lbs, has a pair of 440 hp engines and operates in some of the most severe waters in the US.
A New Breed of Cat: High-Performance Power Catamarans
To help with their hull design, Invincible brought in Morrelli & Melvin, a naval design firm that specializes in multi-hull vessels of all types, from Hobie cats to America's Cup racers to big power cruisers. The Invincible catamaran uses a semi-asymmetrical stepped hull that has high sides and a wide tunnel between the sponsons.

A Complete Guide to Power Catamarans: All You Need to Know!
The multi-hull powerboat features a catamaran design, with two hulls running down the boat's length, featuring a gap between the two. This configuration makes the boat exceptionally stable at higher speeds, allowing fast movement through choppy water inshore or offshore. The catamaran might seem like a niche boat design.
Catamaran Hull Design
However the key to Catamaran design is you need a higher Cp if you want to sail fast. So a multihull should be at least 0.61 and a heavy displacement multihull a bit higher still. It is difficult to get much over 0.67 without a very distorted hull shape or one with excessive WSA.
The New Cat Class
"The design work on a cat is far more involved than on a monohull," says Larry Graf, who started off his design career by creating Glacier Bay powercats and, today, designs and builds Aspen Power Catamarans. "With a monohull, you design from the centerline out, then mirror it on the computer and pow—you have a full hull. A typical ...
Prowler Series Power Catamaran
The Prowler 1360 is a semi-displacement power catamaran design, following a more traditional style in comparison to some of the more modern power designs such as the Growler Series. The bows have been kept quite square and sharp, and the cabin features large wrap around windows and angular styling. The foredeck runs forward to the front of the ...
Year of the Cat
At 34 feet length overall, the Aspen C107 falls in the middle of the Burlington, Washington-based builder's range of high-speed displacement power catamaran designs with an asymmetrical proa configuration. The C107 is based on the twin-hull design that Aspen founder Larry Graf introduced in 2008.

Catamaran Design Formulas
T c = 0.57. Here we put B TR = 1.9 to minimize boat resistance (for her size) and get the draft calculation for a canoe body T c (Figure 1). Midship coefficient - C m. C m = A m / T c (x) B WL. We need to estimate a few coefficients of the canoe body. where A m is the maximum cross section area of the hull (Figure 3).
Hull for power catamaran
I suppose you could build an ultralight catamaran and get 40 knots with the available power. Look at the chart Ad Hoc posted. At the far right end, 30 knots require 68HP (51Kw) per ton. Even at that speed, your maximum loaded weight/displacement would be 10.5 tons for the available power.
Kurt Hughes Multihull Design
Power Multihulls. These low-drag powerboats give a much better ride and require far less power than other types for target speeds of up to 2.5 to 3.0 times the vessel's hull speed. Excellent economy, a superior ride, and a more extensive cruising range are possible with these displacement multihulls. Some of those catamaran powerboats are ...
