Ha Long bay (literally: Descending Dragon bay; Vietnamese: Vịnh Hạ Long) is a UNESCO World Heritage Site, and a popular travel destination, located in Quảng Ninh province, Vietnam. Administratively, the bay belongs to Ha Long City, Cẩm Phả town, and part of Van Don district. The bay features thousands of limestone karsts and isles in various sizes and shapes. Ha Long Bay is a center of a larger zone which includes Bái Tử Long bay to the northeast, and Cát Bà islands to the southwest. These larger zones share similar geological, geographical, geomorphological, climate and cultural characters.

Such a rotation would be detrimental for the operational efficiency of the assembly, and is counteracted by at least one (and often more than one) stabilising member which typically is located halfway the length of the main floating body.
Although such a stabilising member effectively reduces drag induced rotations of the main floating body, due to its mass and area it also causes severe bending stresses in said main floating body when the latter is subjected to reciprocating movements caused by waves, among others. These bending stresses require a stronger and thus heavier main floating body.
