Design Number 348
The Mary E is the first of the Coasters built without the split-level deck change near the middle of the boat. For living aboard, this layout is similar to the very functional classic houseboats of the pre-WW2 era.
This change makes for the major operations all taking place from the deck level where the pilothouse is located. The lower cockpit also gets some activity in line handling.
She is designed to be a summer home for an extended family of grandparents, parents and grandkid. Thus, there are two master suites plus the small kids stateroom tucked in outboard of the stairs on the lower deck.
From comparing the drawings to the photos, you can see where some changes were made at the request of the owners to the layout of the galley and saloon. She ended up with fewer windows and more lockers and storage. There was also a vertical ladder added from the lower cockpit to the middle deck, just aft of the saloon/stateroom bulkhead, which is useful when maneuvering. The saloon has an apartment sized washer and dryer outboard of the stairwell in the locker space there. Both suites have heads with shower stalls, giving one on each deck level.
Designed for use on the Great Lakes, where the water gets hard in the winter, she has a closed cooling system and dry stack exhausts. Thus, she can be run when there is ice around and the skin coolers will still dissipate the heat from the engines into the water. There is an exhaust uptake just aft of the saloon and upper stateroom for the dry stack setup. If one wanted to have wet exhausts, this space could be used for additional deck space.
The stairs also lead down to the workshop ahead of the engine room. There’s good tool and shop space there, even if there is but sitting headroom. The engineroom also has sitting headroom, sufficient to get around the engines and readily work on them. There is another version, in conceptual form, with the split level, raised pilothouse, known as the 42′ Tug/Coaster.

*CAUTION: The displacement quoted here is for the boat in cruising trim. That is, with the fuel and water tanks filled, the crew on board, as well as the crews’ gear and stores in the lockers. This should not be confused with the “shipping weight” often quoted as “displacement” by some manufacturers. This should be taken into account when comparing figure and ratios between this and other designs.
