Maritime Coastal Defence Vessels (MCDVs)

[Navy_Pete]

There is nothing wrong with the displacement of the MCDV's. They just weren't built for speed, but rather for very low speed maneuverability and to pull heavy loads (sweeps). Build a sleeker vessel with a pair of VP screws on fixed shafts of the same displacement with a hull developed for speed and on the same displacement, you will get a much more seaworthy vessel capable of around 26 Kts (but your bridge wont be so high above the water ).

They are also insanely stable, which is what makes them a brutal ride; they are rated for something like 150 tonnes of ice, which is nuts at that size of vessel. Their GM is something stupidly high and way outside the target range for comfortable ride, but why you get beat to heck on them. They are so stable they just slap back upright uncomfortably fast.

Yes they can take a bit of ice.....
