The Jarvis 17' motor launch has been drawn up for clinker/ply construction - a building jig is made which consists of chipboard mould shapes mounted on a strongback. Ribbands (stringers) are inserted into the moulds at each lap and these help in defining the shape of each plank. The ribbands can be left in the hull if 6mm ply is used for the planking or, be removed as part of the jig if 9mm ply planking is used. The launch has 2 berths in a cabin/cuddy and she has a large cockpit for fishing. Outboards up to 25-30 hp may be used for most purposes although she will take bigger.The bench seats in the cockpit have stowage lockers.
