Sea dredger

Draga marittima

"This is the way to clean up a port. The plough will have in its front share and knife-like spikes."

This study for a dredging and cleaning boat is widely innovative. The digging tool, called bucket, is pulled and lifted by a double rope worked by two large wheels. This means that the dredger can work with strong tractive forces. The numerous anchors counterbalance the stresses.

Codex Atlanticus, sheet 842 1486-90
