Two vessels are in service –
“Hamayu” named after the flower of Yokosuka City
and “Soleil” named after the flower of KitaKyusyu City (sunflower).
Taking advantage of the high speed of the vessels
(navigation speed 28.3 knots; about 52.4 km/h),
they will operate between Yokosuka and Shinmoji in about 21 hours.
