Default Check the deadrise

If you're concerned about the ride, don't pay any attention to whether a boat is called a bowrider or a deckboat. The critical factor in determining ride comfort is deadrise.

Deadrise is the angle of the bottom of the hull from horizontal at the transom. There's a good description of deadrise at http://www.tropicalboating.com/power...ull-angle.html. In plain terms deadrise determines the ability of a hull to cut through a wave rather than bouncing off the top of it.

More deadrise (generally above 20 degrees) will give a more comfortable ride, especially in rough water, but require more power to attain a given speed.
Less deadrise (below 20 degrees) will give a rougher ride but requires less power (and speed) to get on plane. Low deadrise boats (18 degrees or less) also may have shallower draft which helps to avoid contact with underwater obstructions; Lake Winnipesaukee has a few of these.

Every boat manufacturer lists deadrise in their specifications.
