Bodrum Tırhandili

Bodrum tırhandili is a traditional boat type uniquely associated with the Bodrum district of Muğla Province, characterized by a symmetrical double-ended hull form. These vessels are defined by a length-to-beam ratio of 1:3. The Bodrum tırhandili features a broad-bellied, sturdy hull with high maneuverability and is steered using a yawl rudder system. The bow is spoon-shaped while the stern is pointed; this symmetrical design becomes particularly evident when viewed from above.

The name Bodrum tırhandili derives from the Greek phrase “trea kena,” meaning “one-third,” reflecting its characteristic proportions. The design has evolved over centuries to suit the region’s wind and wave conditions. The hull form was shaped according to its intended use and available construction materials, with pine, chestnut, and maun wood being preferred for the structure. For deck construction, teak or iroko wood is used.

Historically, the Bodrum tırhandili first appeared in the Republican era with the vessel named “Atilla,” built in 1933. Initially used for cargo transport, these boats were later adapted for fishing and sponge harvesting. Today, they are primarily employed for blue cruising and tourism. In recent years, renewed interest has emerged thanks to the “tırhandil cup” sailing races organized annually.

The production of the Bodrum tırhandili begins with a design process tailored to the user’s requirements. This process continues through engineering stages compliant with relevant laws and regulations. Manufacturing is carried out in accordance with ISO 9001 and CE standards, following the rules of Turkish Lloyd and other international classification societies.

During manufacturing, wood, steel, or composite materials are used. Wooden vessels are built using traditional clinker or laminated methods; steel vessels are constructed by welding; and composite vessels are produced using hand lay-up, vacuum bagging, or vacuum infusion techniques. In wooden hulls, the process begins with the placement of the keel, stem, and sternpost, followed by the installation of frames, stringers, and ribs. After the hull planking, deck, and superstructure are completed, machinery, rigging, sails, and fittings are installed, along with interior and exterior furnishings. The final stage involves painting and varnishing.

The production duration varies according to the vessel’s length and equipment specifications, typically ranging from five to twenty-four months.

The Bodrum tırhandili was registered as a geographical indication on 17 September 2025 under Law No. 6769 on Industrial Property. The Bodrum Chamber of Commerce is the registered owner. The geographical boundary is limited exclusively to the Bodrum district, and all production stages must occur within this defined area.

Inspections are conducted at least once annually by a three-member oversight body coordinated by the Bodrum Chamber of Commerce and comprising experts from the Maritime Trade Chamber and Muğla Sıtkı Koçman University. Inspection criteria include the vessel’s adherence to characteristic features, compliance with production methods, and correct use of the geographical indication mark.
