Her maximum draft was 28 feet 8. She displaced 9, long tons when light, and 21, long tons with a full load of dredging spoil. Her hull contained twelve hoppers which could hold, in total, up to 8, cubic yards of dredging spoil. These hoppers ran for feet 55 m of the ship's length. Essaysons was propelled by two four-bladed propellers which were 16 feet 4.

She was capable of speeds up to The ship's two oil-fired boilers developed high-pressure steam psig for propulsion and electrical generation. She was crewed by 18 officers and men. Dredging continued around the clock, so the crew worked in shifts. The ship had a machine shop, store, a crew lounge with a ping-pong table, a six-bed medical dispensary, laundry facilities, a cook staff and full galley for meal service, and separate dining rooms for officers and men.

Essayons was at least the third vessel of that name to serve with the U. Army Corp of Engineers and the second dredge. An earlier Essayons was built in to dredge the mouth of the Mississippi. It is a French word which means "Let us try. Essayons was designed to dredge New York Harbor. She sucked sand, silt, and mud off the bottom of navigable waterways to increase their depth, creating a channel allowing larger ships to pass.

She pulled two suctionheads, referred to as "dragheads", along the seafloor as she moved slowly through the water. The dragheads were connected to pipes which were 36 inches 91 cm in diameter called "drag arms" that descended from both sides of the ship.

Using two winches each, these drag arms could be lowered to reach bottom as deep as 60 feet 18 m. Loose material on the seafloor entered the dragheads and was pulled up through the drag arms by 1, horsepower electric pumps. It was then deposited in a hopper in the middle of the ship. All the hoppers were filled after one to two hours of dredging.

Here she opened doors in the bottom of the hoppers, allowing the dredge spoil to fall to the sea bottom. The uniquely long transit associated with the disposal areas off New York Harbor resulted in a design which gave her twice the hopper capacity and significantly higher speed than other dredges at that time. While Essayons was designed to dredge New York Harbor and spent much of her time doing so, she was capable of dredging any major waterway.

She had difficulty evaporating seawater to provide fresh water for the boilers.

Her crew had to clean the evaporators more frequently than normal to keep the salt at bay.
