Application of Maryland Clam Dredge on the Maine Coast
The Maryland hydraulic dredge was adapted for use on a fishing dragger vessel for use along the Maine coast. It was found that by applying conservative engineering practices the hydraulic dredge was made to work under the most severe condition. This condition being in the very stiff blue clay. Modifications were made to the hydraulic head to obtain the distance the water jets travelled through a liquid medium down to a minimum. This modification also caused the water jets to shear the very stiff blue clay. The combination of these two effects resulted in the very stiff blue clay being broken up into nodule-like chunks. Under this condition, the soft shell clams were being floated out of the sediments and carried up the conveyor for easy picking. It was found that the dredge was flexible enough so it would work in most areas found along the Maine coast.
