In this segment host John Greviskis discusses the different types of V-hulls, and he describes the pros and cons to each one.
The V-shape hull is also called the "deadrise". You can see the deadrise under the transom. V-hull's are designed with various degrees of the "V" shape.
- Thirteen degrees or less is called a shallow "V" (figure A), which are mainly used for cruising around or lake fishing. They are stable only at a low speed or at rest. This is not a good type of hull for fast speeds or choppy waters.
- Fourteen- to 17-degree V-hulls are referred to as a modified "V" (figure B). This type of hull would do well in choppy waters and at a high speed. It'll also be stable at rest or lake fishing. Modified V-hulls are a good "happy medium". It's not great in all water conditions, but it's not terrible either.
- Eighteen degrees and up are the deep "V" hulls (figure C). They will slice through choppy water with great stability but will rock back and forth while resting. If your prone to motion sickness, you might want to stay away from this type of hull.
There are a few boat terms you should be familiar with and make sure that you check out these parts for quality while shopping around for a used boat hull.
Keel -- The centerline of the boat that goes from the bottom of one end of the boat to the other.
Lifting Strake (figure D) -- Incorporated into the hull bottom to add lift and break the suction from the water. It also stabilizes the boat when traveling at a high speed and will aid in sharp turns.
Chine -- Located on the transom, used to move the water spray in a particular direction. In this episode, host John Greviskis looks at a boat with a reverse chine (figure E), which keeps the water spray down and away from passengers.
