Type of high-speed, wave-piercing craft.
A Very Slender Vessel (VSV) is a high-speed, wave-piercing craft. It is designed to give a comfortable ride over long, high-speed transits in high seas.[1]
Normal boats travelling at high speed in rough seas can produce a very uncomfortable ride with g-force as high as 20g. Wave piercing vessels avoid this by going through waves instead of over them, at speeds that can exceed 60 knots (110 km/h).[1][2]
Military
North Korea
It was revealed in 2015 that North Korea had under development a VSV attack boat, reported to be deployed on the western side of the Korean peninsula.[3] It was first detected on trials by satellite surveillance late in 2014. The first images of the completed vessel were released by North Korean media in July 2018, after a visit to the Chongjin shipyard by leader Kim Jong-un.[4]
Singapore
The Singapore Army operates VSV craft in special forces units. It was speculated in 2018 that they were to be replaced by new craft.[5]
United Kingdom
VSV craft such as the Royal Marine VSV are used by the Royal Marines and the Special Boat Service.
