Have you ever dreamed of living aboard a truly magnificent vessel with the hopes of spending the winters in the Islands and summers on the Chesapeake or cruising Maine? Have you been worried about following these dreams with the high cost of fuel?
Mosey is a long range, heavy displacement trawler with the capabilities of crossing any ocean.
The extremely capable John Deere engine is slow turning and uses only 3 gallons of diesel per
hour at the comfortable cruising speed of 8 knots. Even though her top speed is significantly
greater, 8 knots is the “happy speed” for the vessel, her engine and her crew.
The hull of Mosey was built by Harry Hutchenson in Oxford, Pennsylvania using semi-custom
plans from the naval architecture firm Sparkman & Stephens. The hull was originally intended
as a research motor sailing vessel for US sponsored offshore ocean survey work pulling an array
of sonar units. Included in the initial hull construction was a dive well for servicing the sonar
units. Unfortunately, the government contractor paying the bills passed away during the
construction and the government funds were diverted. The hull became available, and I was
extremely fortunate to acquire such a capable and well-designed vessel.
The water flow around the hull was of upmost importance to avoid turbulence interfering with
sonar array. The hull was required to have perfectly bent chines with near zero surface
imperfections on welded seams. The application of heat and cold produced a metal hull with the
required bends and no residual stress.
The keel plate is 1" thick mild steel. Keel sides are 3/8" and tapering to ¼ inch above the
waterline. The weather decks and above are built using 3/16" steel plate. The flybridge and mast
were constructed using 3/16" marine 5083 aluminum plate. Detacoupler was used to bond the
aluminum flybridge to the mild steel pilothouse roof. After several years, there are absolutely no
signs of galvanic issues. The aluminum mast is attached to the pilothouse roof using edge on
316 flat bar and Delrin insulation.
An analysis was done of the original center of gravity and center of buoyancy, and then
compared to the new vessel design with the added weight of the pilot house and saloon
structure. It was determined that 12,000 pounds needed to be added to maintain the same
ultimate stability. Approximately 9,000 pounds were added inside the 2-foot wide keel in a
location just forward of the engine. Another 3,000 pounds were added toward the bow to help
keep the vessel from squatting when running close to hull displacement speed since most of the
pilot house weight was added toward the aft. For ballast, steel flat bars 1” thick and either 4” or
6” wide were cut to fit for additional weight between structural members of the keel. Each bar
was coated with 100% solids epoxy and layered in a bed of epoxy. To ensure the ballast would
stay in place should the vessel ever become inverted, 2-1/2” steel angles were welded over the
ballast and attached to the keel sides. A sufficient amount of epoxy was then added to the surface
of the ballast to assure against water impregnation.
After the vessel was launched, a stability test was done to determine how effective the ballast
was in creating the desired amount of stability. A good rule of thumb is that a full displacement
vessel should complete a full cycle of rocking in about 1 second for each meter of beam. This
equated to approximately 5 seconds based on the actual hull width of 17 feet. The rocking test
completed cycles in approximately 4-1/2 seconds, which indicated a slightly stiff vessel. This
test was performed with minimum fuel on board and no water. The design concept was that the
hull should be stable regardless of the quantity of fuel. With the addition of fuel, the vessel
would become a little stiffer and have motions a little less pronounced than most rounded bottom
vessels.
The design concepts were created with the goal of creating a safe and capable passagemaker.
Mosey is a 1-owner yacht. The hull ID was applied for from the state of Maryland in 2004, but
the vessel was not operational until 2007. She has a proven track record of spending months at a
time anchored in the Exumas and exploring the US East Coast from the keys through Maine.

Single engine and no wing or take me home engine auxiliary? No specs, no price, no range? A household AC? Need to improve video making.
