What Type of Hull Should I be Looking For

There are many hull designs to consider when purchasing a boat. Let’s take a look at three of the most common hull designs all of which are considered planing hulls. Planing Hulls at higher speeds will begin to level off on top of the water and make less waves and friction.

FLAT-BOTTOM HULLS Figure 1 a)

Many planing hulls are variations of the flat bottom hull and have the following characteristics:

  • Good load carrying
  • Inexpensive to construct
  • Below average in holding a courser at low speeds and tend to slide or drift
  • Produce a much rougher ride in waves

VEE-BOTTOM HULLS Figure 1 b)
The VEE-shaped hull, although a flat-bottom hull, has a pronounced Vee-shape to its bow where it cuts the water. Characteristics include:

  • Good ability to hold steered direction at speed
  • Deep Vees perform better in rough water
  • Deep Vees also tend to roll at rest

CATHEDRAL HULLS Figure 1 c)
Sometimes called the Dual Vee or Tri Vee hull due to its prominent fore design turns into a flat hull aft and perform well with these characteristics.

  • Greater Stability
  • Good Tracking at low speeds
  • Good load carrying capacity
  • Tend toward lower freeboard heights
  • Uncomfortable at speed in rough water
