Recommend hull type depends on the body of water you are fishing and size.

Catamaran vs v hull boat. Ever since the Polynesians started crossing oceans on catamarans when much of the civilized world was still afraid of the sea the idea of the twin hull has ebbed and flowed in popularity. The faster the boat goes the more air it packs. Caught an unplanned side by side comparison of a power catamaran and a V hull Sea Ray leaving Fort Lauderdale on calm water.

Catamaran hulls turn very aggressively and do so quite well both right and left. A monohull typically sits deep within the water while a catamaran sits much higher on the water. The traditional V-hull meanwhile has a far more predictable center of resistance to ride on.

For the uninitiated the boats draft refers to how deep the boats hull sits within the water. Like anything else you have to sea trial them and see. That makes for less hydrodynamic resistance than a V-Hull meaning less propulsion.

For example if your 250-pound buddy gently leans on you what you feel is different than if he were to hit you with a running tackle. Cat lovers contend the boat is built lighter with two parallel hulls of equal size and a wide stabilizing beam. Like anything else you have to sea trial them and see.

In my ASE senior research project I discuss and analysis the differences between flat bottoms monohulls catamarans and tri-hulls. Sometimes called a warped plane this is the most common hull for small boats because it combines some of the best characteristics of the other shapes. The advantages of catamarans are great resulting in fast speeds.

Size of the hull is an important factor if your side is on the choppy side-- the larger the hull the better for chop 30 or more. Monohulls heel upwind and when the wind is on the beam while catamarans stay flat but pitch upwind. If you want to use a diesel motor there is more space available for an engine in a monohull than in the cats slender shallow hulls making it more accessible and easier to work on.
