Design
The Kingston-class patrol vessels have many admirable qualities, including crew comfort and ship manoeuvrability, but they represent some design compromises. The program was conceived to advance the use of commercial, off-the-shelf (COTS) equipment and construction techniques in a ship designed to military specifications.
While the Z-drive thrusters make the Kingston-class vessels extremely manoeuvrable (able to turn within their own shiplength) and the engines are quite powerful and fuel-efficient, the hull shape, with a blunt stern and "hard" chine designed for minesweeping, prevents the ship from achieving a "sprint" speed and the patrol vessels of other nations are considerably faster. However, the Kingstons' top speed is faster than that of most mine warfare vessels and is comparable to most large non-naval sea-going vessels.
The hull is a longitudinally framed structure and has been designed to minimise steel weight. The construction involved initial production of partially outfitted steel modules which were made into sub-assemblies and then integrated into the ship. The decks were assembled upside down with pre-outfitting of the underside of the deck prior to installation on the ship. In contrast to many modern mine warfare vessels, which often have hulls made of non-magnetic glass-reinforced plastic or similar material, the Kingston class have conventional steel hulls. The vessels are, however, equipped with a magnetic degaussing system that allows the ship's magnetic signature to be manipulated in three dimensions to minimize vulnerability to magnetic mines.

“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”

“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
“To nourish children and raise them against odds is in any time, any place, more valuable than to fix bolts in cars or design nuclear weapons.”
