Jon boat
From Openwaterpedia
noun - Jon boat (or Johnboat) is a flat-bottomed boat constructed of aluminum or wood with one, two, or three bench seats. They are particularly useful for open water swimming events due to their level of stability. Because the hull of a jon boat is nearly flat, it tends to ride over the waves rather than cut through them as a V-hull might, thus limiting the use of the boat to calmer waters. Jon boats typically have a transom onto which an outboard motor can be mounted. They are simple and easy to maintain, and inexpensive with many options to upgrade.
Jon boats are available commercially between 8 and 20 feet (2.4 and 6.1 m) long and 32 to 56 inches (81 to 140 cm) wide, though custom sizes may be found. The simple design includes an open hull, without a bilge, leaving the ribs exposed. Many individuals choose to cover the ribs, producing a flat, level surface.
