"This is the way to clean up a port. The plough will have in its front share and knife-like spikes."
This watercraft for dredging maritime ports is formed of two hulls united by a platform. The platform has a long slot down the center, through which passes a double cable connected to two wheels fixed at the extremities of the hulls. An excavating bucket is fixed to the double cables. Six anchors per side are mounted at the extremities of the hulls. The double cable allows easy drawing and lifting of the bucket, even when the forces of traction could be significant. The numerous anchors allows counterbalancing of the efforts the dredge was submitted to.
The model is based on the drawing:
