SPC is a membership club that enjoys outrigger canoeing. Outrigger canoes are traditional boats from Hawaii and Polynesia. It is characterized by having a buoyant body (ama) parallel to the canoe. Ancient people are said to have used these canoes to cross the Polynesian islands. Today, it is popular as a sport all over the world, regardless of age or gender. Every weekend, SPC enjoys rowing a 6-person outrigger canoe (OC6) by the beach and in the sea near Nagai, Yokosuka City. The club is a non-profit organization run by volunteers.
