Escargot -- pedal powered river boat

ESCARGOT is one of a series of small boat designs using pedal-powered screw propulsion. It was developed for cruising on the sheltered waters of inland canals, and to fill the gap between canoes or kayaks and motor-driven cabin cruisers. It provides simple live-aboard facilities for two plus one, in association with quiet, non-polluting aerobic human-power propulsion.

Based on a square-ended punt-like hull with dimensions of 18'-6" x 6'-0" it is built of exterior-grade plywood and soft wood framing. Accomodated under 4'-6" sitting headroom are two berths forward, with an access hatch over, followed by toilet and hanging space and then a "salon" with table seating and food preparation counter. (The table lowers to provide a third berth.) Aft of this is an open cockpit with the two side-by-side pedaling positions. An outboard swing-up rudder is controlled by a tiller from either position. Propulsion is provided by two swing-up "Seacycle" drive units in wells built into the hull and transom. At a sustainable pedaling rate of 50 rpm the boat moves a leisurly 3-4 miles per hour.
Detailed working drawings and construction procedures for the advanced amateur builder are available for $80 US from: Philip Thiel, 4720 Seventh Avenue NE, Seattle WA 98105 USA.
