P1 Panther 28SS Technical Specification

This 28 ft. sport racer is powered by a 250+ hp engine. This propels the boat to speeds up to 70+mph in flat water, and its lower center of gravity provides greater stability and improved handling. There is a removable rear cowl to access rear bench seat for additional passengers, when the Panther is used as a leisure craft. It is built to NMMA and ABYC boating standards, and CE certification is pending.

Dimensions: length: 28ft (8.7m x 2.25m x 1.6m)
Engine: 250+ hp
Speed: 70+ mph
Weight: 3550 pounds (dry)
Tank: 260 liters
Price: Boat and engine complete $89,000 after P1 racer discount (price + taxes)


Composite core and stringer materials control weight and simplify the lamination process, with vinylester resin to bond the matrix. The boat's 100 percent composite construction created a completely unitized structure for endurance and safety.

The Panther has a bi, tri, and quad-directional knitted fiberglass hull with twin step shape.

Safety features: crumple zones and Kevlar cockpit give 360 degree impact-penetration protection.

Length from the bow to the bottom of the transom and overall. The length from the bow to the transom (not including the notch) is 26'8". The LOA is 28'9" (Beam is 7'9")

The boat comes with a power jack plate, providing 5" of vertical travel. This can place the prop-shaft from 2" to +3" in relation to the keel.


The cockpit design was engineered to provide many of the elements of an enclosed cockpit in a "commercially viable" open-cockpit configuration. The cockpit liner is integrated into the deck component, independent of hull sides. The space between the cockpit liner and the hull sides is supported by bulkheads creating “crumple zones" providing a 360 degree additional layer of protection for the pilots from both water intrusion and collision impact.

Access to the forward compartment of the boat is only available through a deck hatch, leaving no open access for water to enter the cockpit at the pilot level to cause hydraulic related injuries. Placement of driver/navigator inside the cockpit ensures maximum protection from water impact and collision, with their shoulders at or below the level of the side of the deck line, within the isolated cockpit liner. A polycarbonate wind screen provides secure protection from wind and water while providing outstanding visibility.

The Panther comes standard with the following: Recaro suspension seats, 30 gallon ballast tank, carbon fiber dash, Garmin 740 NMEA Compliant Chart Plotter, external hydraulic steering, integrated VHF intercom system, poly-carbonate windscreen, integrated lifting hardware, stereo.

Other optional equipment can include 15" chart plotter, configuration for driver/throttleman operation, retractable boarding ladder, ski-pole, 4-person intercom integration, rear seat comfort package, custom graphics.
