Origins: These handsome, practical row boats were routinely built by Nova Scotia shipwright, Jim Smith, in six days, fully painted and ready for the water.
Dimensions: Length: 10ft. 2ins. Beam: 3ft. 10ins.
Weight: 120 pounds (1/2 in. planking)
Materials: (orig. boat) Eastern white pine planking, red oak frames fastened with galvanized iron clench nails and bolts.
Plans: Original Sea Urchin measured by Sam Manning, 1985. Plans drawn by Bill Nielsen, 1993. Now on permanent exhibit at the Maritime Museum in Halifax, Nova Scotia. New Sea Urchin built by a class in Newport Beach.
Time to Build: 3-4 weeks with part-time help.
Materials: (new boat) Eastern white pine, white oak frames. Fastened with copper rivets, bronze ring-shank nails and bronze carriage bolts.
Cost of materials: $800-$1200
Special features: I bought the original boat, second hand from Jim Smith in 1968. Named Sea Urchin by my children the boat is easily rowed and handled by youngsters. It tows well and makes a good tender to a larger vessel although rather too heavy to be conveniently carried on deck.
