This is a modified V. They're a tunnel bottom with a Vee design. They don't trap air quite as well so it takes a bit more to get them out of the water. You're next question is probably "will they beat a cat?" The answer is argueable. Technically no. However, if you get the air under a boat like this a put it against something like a mach 22 with the same power... the mod-v will match if not beat the mach. These results do vary and that's why I say it's argueable. This doesn't apply to all mod-v's but I know 2 guys. One has a mach 22 with a 300x and a guy with the same model of boat as pictured below(sleekcraft SST) with a 300x and the SST will beat the mach by about 5-10 feet. The next arguement will be that the props are different and the answer is no. They're just as fast as a cat but it's a hell of a lot harder to get them there. If you want a ride I'll definatly give ya one. They're one hell of a rush.
