DESIGN AV ALUTON 38’ FRAKTBÅT FÖR KUSTNÄRA TRANSPORTER

Sammanfattning: This master thesis is about designing and dimensioning a boat for transport of caravan, car, trailer or ATV. Buoyancy and stability are important properties as the pontoonboat should also be able to serve as a workboat. Many of the vessels on the market today that is being used for similar purpose are stable enough, but their hull is often similar with barges and thus too slow. This work has been to construct a boat that has good stability but also has a hull that enables it to move faster, is more maneuverable and having a more attracting design than today’s barges. This study includes requirement analysis, production of general arrangement, selection of appropriate material, design analysis and hydrostatic analysis. The hull design is based on DNV’s regulatory Standard for Certification of Craft. As the boat should be adaptable to accommodate customer requirements, it is fitted with outboard motors. This allows the user to easily change motors to fit the speed requirement of the boat. Sufficient power to meet speed requirement is decided after tests with prototype. The transom is designed with enough space for two engines when this allows for improved maneuverability. The work resulted in a boat that is 11.5 m long and 3.8 m wide. Aluton 38' is made entirely of aluminum and can take loads up to 3 tons.
