Italeri 3103 Italeri 3103 Mechanical ROWING BOAT Prefab Model Leonardo Da Vinci description On sheet 945/r/ of the Codex Atlantic, Leonardo da Vinci drew numerous devices for the construction of a mechanical boat. One or more riders can take turns controlling the two pedals. The pedals transmit reciprocating motion to the central mechanism. Here, the reciprocating motion is converted to linear motion, and a series of gears transmits the motion to two large blades located on the sides of the boat. The central mechanism is detailed by Leonardo on another sheet, 30/v/, and the mechanism is operated by means of springs concealed in two main wheels, which alternately engage the outer rings, converting the motion from reciprocating to linear.
