The Shannon 51 Aegean was originally built in 1984 to Shannon's highest standards Our building specifications meet and exceed Lloyds, ABYC and Gibbs & Cox. The following represents some of the features incorporated in the design and construction of Shannon Aegean 51:
Internal cast lead ballast in the keel with reinforced polyester compound poured over and around the lead to fill any small spaces between the pieces. The entire keel area is encapsulated with alternate layers of mat and roving to create a strong and watertight secondary hull bottom. No keel bolts are used on any Shannon avoiding corrosion, failure or loosening.
One piece hand layed up fiberglass hull and deck. The 51, like all Shannons, has a sophisticated laminate schedule that utilizes semi-rigid Airex foam core in the hull and rigid PVC foam core in the deck laminate. No balsa wood coring, which is common in production boats, is used anywhere in the fiberglass structure. Isophthalic gel coat and e-glass are incorporated throughout the hull and deck. Where through-hulls or deck hardware penetrate the laminate it is de-cored and filled solid to prevent compression loads. Areas like the bow, keel leading edge and base, transom corners, chainplate locations and skeg are further reinforced. In the 24 years since Shannon was the first company to move to composite foam core construction, there has never been a case of de-lamination or laminate failure.
A wide internal deck flange, uncommon to Far Eastern and production built boats, is molded into the sheer of the hull to accept the deck for an optimum hull to deck joint. Instead of corrosive aluminum rivets, as is also seen in production build boats, the deck is bolted with 3/8" stainless steel bolts on 8" centers as an added protection from deck separation at sea. All chainplate knees and the mainmast step are solid fiberglass molded to the hull. All deck hardware such as lifeline stanchions, genoa tracks, traveler bridges, winces and blocks are backed and thru-bolted. All bolts are accessible for removal and maintenance.
Protected propeller in aperture
Bow platform for dual anchor stowage with a divided chain locker.
The cockpit was carefully designed for safety offshore as well as comfort. It is stepped to provide excellent visibility from both the forward and the aft helm stations. The hardtop incorporates armor plate glass with windshield wipers and washers for inclement weather sailing. A removable (using a wrench) watertight hatch is molded into the cockpit sole for engine and generator maintenance and removal. Large oversized scuppers are located for cockpit drainage for bluewater conditions. It is a few easy steps from the protected forward helm to the outside Edson pedestal helm station. All new cockpit winches are electric with manual backup.
There is a spacious lazarette aft which is vented overboard for propane storage, spare lines, fenders, scuba tanks and other equipment.
All opening bronze portlights
Four opening skylight cabin hatches
Rod rigging on the main and mizzen mast, instead of wire rigging found on most sailboats that is totally dependent on swages that are prone to failure without evidence.
Large "U" shaped galley set up for food preparation in offshore work. Located amidships, it is convenient to the deck and central to the interior accommodation. The "U" shaped configuration provides for the most efficient utilization of the three key galley areas; the sinks, the stove, and the refrigerator.
The hydro-dynamically shaped fiberglass centerboard is reinforced with an internal stainless steel skeleton welded to stainless bar stock for strength. for maintenance in remote areas of the world, the entire centerboard can easily be removed while the boat is in the water by using scuba gear to pull the stainless steel pin. The centerboard is operated from a manual winch located in the cockpit.
The rudder is reinforced with a 2" solid stainless shaft welded to a stainless steel skeleton. The one piece shaft extends from the cockpit to a solid bronze rudder shoe thru-bolted to the hull at the skeg. The rudder has a designed indent to allow propeller and shaft removal without unshipping the rudder.
Electrical wiring is color coded and run on the perimeter of the vessel under the deck flange for accessibility. All marine grade wiring meets or exceeds A.B.Y.C standards. there are 12 volt dome lights and 110 volt outlets conveniently placed throughout the interior. There are 8 new marine grade 120 amp batteries that are divided two for engine starting and six “house” (720 amps).
The 250 gallon fresh water system is divided into five self-trimming stainless steel tanks. Each tank has in independent fill and isolator control valve in the galley and all tanks are removable. The fresh water system consists of a high-capacity pump with accumulator tank. A foot pump in the galley provides a backup to the fresh water system. The hot water system operates off the engine and 110 volts. Both the forward and aft stall showers have their own sump pumps and strainers that discharge above the waterline. All water tanks are removable a Shannon exclusive feature.
Fuel system: There are 4 new 5052 marine grade alloy diesel fuel tanks providing 150 gallon capacity. Each tank is equipped with an isolator valve for fuel management. Dual Racor fuel filters are designed for quick switch over. All tanks are located low in the center of the 51 for positive trim purposes. All fuel tanks are removable a Shannon exclusive feature.
Interior accommodations in Shannon 51 Aegean utilizes oak and mahogany fine woods. Bulkheads are 1" thick and the cabin sole is 5/8" solid teak with holly inlays. Grab rails below are thru-bolted for safety. Shannon interiors are characterized by exquisitely detailed woodwork utilizing corner post construction, solid woods, and screwed with bronze or stainless fasteners, glued, and rabbeted joinery. Hull surfaces, including those in lockers, are treated in traditional style with mahogany ceiling, set 5'/8" from the hull, which creates a semi-insulated interior in addition to the insulation factor provided by the Airex core in the hull laminate. There are no nails, a common production boat practice, used anywhere on a Shannon because nails tend to loosen and fail over time. No glued fabric/foam covering on the hull sides or deck overhead is used anywhere on the 51.
