Can any one name a few countries and names of ships for examples that used V shaped hulls? I was wanting to do some research over the hulls and see what classes of ships if it wear a battle ships or cruisers or destroyers. not much was turning op in Yahoo/Google searches .
"V" hulls (very deep keels) are needed for ships with VERY large tendencies to move w/ the wind (ie drift). Namely, sailing ships. Since they are narrow & deep, in order to get greater displacement for a larger ship, you either have to go very long and narrow, or have a hugely deep draft. So, you won't find anything modern (or even steamships ~1850's) with this shape
About the closest you'll find would be a Destroyer. Very narrow beam for length. Even they had rounded or flat bottoms for much of their length, though
