Betina gajeta is a wooden boat between 5 to 8 meters in length and 2 to 2,60 meters in width, without a deck the entire length of the boat. It has a more robust shape than the Komiža falkuša or Korčula gajeta. Betina shipbuilders managed, through much innovation, to reach the proportions and the shape of a boat perfectly adapted to the everyday needs and the rural economy of the townspeople of Murter and Betina. The rural economy was mostly dependant of the oversea estates located on Kornati, islands in the Murter archipelago and in the Modrave area – a fruitful area between the sea and the Vrana Lake. Considering the fact that the people of Murter used to be labourers and cattle breeders, rather than fishermen, Betina shipbuilders altered the fishing gajeta into a boat capable of satisfying their multiple needs. The primary function of the gajeta was transport of different types of cargo (food, produce, livestock, construction material). Gajeta is a family boat by its dimensions, and all the crew members had to know how to navigate it. The women often used the boat. Gajeta was used for fishing as well. The boat that was made to fit all the needs of the people of Murter had to be, above all, a capable, safe and sturdy means of transport. There are two types of the Betina gajeta, and the turning point that led to the construction of the second type was the incorporation of engine into the boat. This process started in the 1940s and 1950s.
The first, original type of gajeta, with a flat keel and a straight frame, which stayed the same between the beginnings of the 18th to the middle of 20th century, is a robust and a very stable boat. Its bow is quite high and its stern only a few centimeters lower. Modern times brought new requests and adjustments, therefore new boats became narrower, without sails and with cabins and upper cabins. The flat keel got a slight tilt and a long rudder was replaced with a shorter one. The stern post was adapted for the installation of the slide shaft. However, the Betina gajeta has kept its unique lines. Betina shipbuilding is different from others that built the same or similar types of boats and it has some recognizable specificities. Some of the typical, and recognizable, characteristics of the Betina gajeta are: the oar grips (sohe) with the distinctive U-shape, a step located on the bow of the boat (an element of the boat that made it easier to get in and out of the boat, especially in a rocky, inaccessible parts of the coast), and kantun na mankulu (a boat part that is the most difficult to build, due to the bending of the belt on the each side of the stern).
