The putt putt or pop pop boats we sell at Buzz's BoatYard are mostly from hand made in India. Some of these hand presses take up to 5 or 6 men to operate, especially when they are pressing hulls. Many sections of the deck and fittings are literally cut by hand.
The photos here are of various parts of a pop pop boat factory operation. You will be amazed to see 4 to 6 men hand pressing a boat hull, or cutting out lithographed sections of a boat.
