Boat specifications: Design based on the Tewantin by Tim Weston: 3,4 m long and 1,5 m wide, final weight is 88 kg. Around 6 hp is a good motor size and the boat can safely take 3 persons (probably more). It planes with 1 person and my electric motor (ca 5 hp), but with more people in the boat it does not get up on plane with the electric motor. Materials list: - 6 mm pine plywood, 4 sheets 1,4 x 2,5 m - 9 mm spruce plywood, 2 sheets 1,4 x 2,5 m - About 10 kg of epoxy - Some glass fibre sheet, 160 g/m² - Polyurethane paint, 2 liters (1 litre per side of the boat) - Some planks, screws, etc... The total material cost was around 1000€.
