This configuration still offers the requisite characteristics suitable for EEZ duties--visible weaponry, high speed, good seakeeping, manoeuvrability and hull strength--yet still be reasonably priced.
For those considering the two models, the longer waterline and theoretically better seakeeping are key factors, but this has to be balanced against the challenges of handling a substantially larger vessel, especially in marinas, with a typical cruising couple.
Several tank tests, and numerical simulations, were carried out to assess its seakeeping performance.

She left New York March 6 and encountered her first challenge: stormy weather, which abundantly demonstrated both the inherent seakeeping problems of the design and some more-easily correctable technical difficulties.
The People's Liberation Army Navy (PLAN) has small, fast, and capable craft with good seakeeping capabilities such as the Houbei missile attack craft.
According to Shuttleworth, the seakeeping, a measure of how well-suited a watercraft is to conditions when underway, was monitored as well as the maneuverability with the outrigger engines.
Compared to the Hamilton-class 378s they are replacing, the 418-foot NSC design provides better seakeeping and higher sustained transit speeds of 28 knots, or 30-plus knots sprint speed; greater endurance and range with maximum 90-day patrols and 12,000 nautical miles at 12 knots; an improved ability to launch and recover small boats, helicopters and drones; and advanced secure command, control, communications, computers, intelligence, surveillance, and reconnaissance systems (C4ISR) and ability to handle sensitive information.
Coverage encompasses kinematics; rigid-body kinetics; hydrostatics; seakeeping theory; maneuvering theory; models for ships, offshore structures, and underwater vehicles; environmental forces and moments; and various aspects of motion control including guidance systems and sensor and navigations systems.
The school's current research highlights relating to renewable energy and the environment include: Wind, wave and tidal power research Engineering and seakeeping of wind, wave and tidal power generation equipment during deployment and operation, including logistical implications and, from both marine technology and marine science perspectives, environmental sustainability and offshore energy performance.
The Yin He Long Wing Ship is a kind of ship working with wings (wing-in-ground effect), which has seakeeping qualities as well as airworthiness.
At Germanischer Lloyd, he developed hydrodynamic seakeeping analysis methods for fixed and floating offshore structures, including mooring aspects and crane ship behavior.
