John Seymour modified M.B. Alford's design for the Tursiops Kayak by shortening the length a foot and lengthening to cockpit entry to make it easier to get in and out of the boat. He launched HOBO in Lake of Bays in Ontario, Canada. Knowing he would want to beach HOBO frequently, John sheathed the bottom in fibreglass and epoxy. He also added an external keep to improve her traking ability.
