QB III is not only the nicest Dettling 51 we have ever listed she is one of the finest personal sized yachts we have had the pleasure to represent. From her freshly painted Flag Blue hull to her immaculate interior, to her updated electronics and meticulously maintained machinery and systems, QB III is a rare find.

Even more rare is the fact that the current owners purchased her from the original owners, a very knowledgeable cruising couple who had Ed Dettling custom build the boat for them. Their fastidious ownership and approach to maintaining the boat was continued by the current owners and it shows A perfect size yacht for two people to cruise with occasional guests, she is a proven Great Loop cruiser and a perfect Bahamas and Islands yacht.

If you are looking for your next boat or even your first one, QB III is the perfect choice. Big enough to have all the comforts discerning yachtsmen and women desire but small enough to be handled easily by 2 people. She is standing tall, ready to explore new harbors and discover remote cruising grounds with her new owners, or possibly retrace some of the waters she has already navigated while completing the Great Loop with you at the helm.

Give us a call to discover how easy it can be to own the boat of your dreams, sail off into the sunset and make your fantasies your reality.

Entering through the aft deck doorway will bring you to the most essential section of the vessel, the pilothouse. Featuring a full 360-degree view of your surroundings, visibility is not a concern while underway. A skylight / hatch above adds additional natural light to an already brightly lit pilothouse and doubles as access to the above boat deck. The helm is located to starboard and is equipped with an extra wide bench seat that accommodates up to four. The console is compact but loaded with engine instrumentation and navigation electronics, to the port of which is a large expanse perfect for charts. This raised flooring of the dash has another purpose, by standing on it and opening the ceiling hatch, you are able to control the boat from another station. This express bridge features additional controls hidden in a weather tight compartment and satisfies the allure of open-air cruising. Continuing to

port of the pilothouse is access to the salon and accommodations through a few short steps down. Also, to the far port side resides an additional control station with an autopilot and thruster controls which gives added flexibility underway and ease of docking when going port-side to.

Just four small steps down from the pilothouse resides the capacious salon located at the heart of the vessel and acts as a central bridge between the two staterooms onboard. Expansive 28" windows that run the length of the salon in conjunction with overhead hatches let natural light, and views of the journey, flood into this mid-ship social space. Between these huge windows and 78" worth of headroom, this open layout makes the salon an ideal spot for entertaining guests.

Along the starboard outboard wall is an L-shaped settee complimented by an adjustable teak coffee table which doubles as a dining table by raising up and folding out. This settee, along with the twin arm chairs to the port side, provide comfortable seating for up to six in the salon. A 32" flat screen television is hidden away in a compartment on the forward bulkhead below the galley countertop, easily put out of sight when not in use. Storage is accomplished through drawers underneath the settee, shelving above, and cabinet end table fixed between the armchairs to port.

The open layout of the salon includes the galley to forward. Separated by raised countertop and a step down, the galley feels connected to the social activities of the salon yet retains enough privacy to maintain its own space and function. The alcove behind the raised countertop to port encompassed most of the galley. In this area you will find a stainless-steel double-sink, 3-burner stove, icemaker below the counter storage compartments, and ample countertop space. To the starboard side resides a microwave and refrigerator and freezer compartments which are situated to provide additional counter top space when needed.

This vessel provides two comfortable ensuite staterooms suited to perfectly accommodate two couples. These cabins are situated to forward and aft of the salon, respectively. The aft stateroom can be found just two steps down from the salon stair passage and a large hanging locker, guests are sure to enjoy their stay. The ensuite
guest head is fashioned with all the amenities you would expect and also houses the vessel's separate Kenmore washer and dryer.

As for the forward stateroom, this is accessed just past the galley and also features a queen-size berth. With this stateroom being larger than the one found to aft it is typically utilized as the master cabin. The island queen is accessible from either side, each of which is situated with his & hers night stands. Additional storage is provided via drawers, hanging lockers, shelving, and a large compartment below the left side of the berth, which can make an excellent wine cellar. The master head in this stateroom is similar to the guest stateroom's head along with a built-in laundry hamper and more extensive storage space.

A flurry of recent updates have kept both staterooms fresh. These included new carpeting (2017), updated LED lighting, custom insulated window treatments (2017), a master closet remodel (2017), and a new custom latex foam mattress and linens for the master berth.

Deck and Construction Details

The Dettling 51 is built from the keel up with precision, experience, and an extreme level of detail. The hull design is courtesy of Hunt with their deep V hull providing excellent offshore performance. The fiberglass hull construction utilizes Vinylester resin throughout, vacuum bagged core-cell technology, and is reinforced with four foam-cored fiberglass stringers running the length of the boat. Fourteen layers of fiberglass are used to reinforce the hull and deck together creating a single strong, impact resistant unit.

The house and deck both incorporate Divinycell-core fused with 10 layers of fiberglass which provides optimal stiffness and thermal insulation, while remaining relatively light weight. Up on the deck you will find a spacious teak aft deck cockpit with a mounted table and deck chairs allowing for alfresco dining and entertaining. Above the extended hardtop of the boat deck provides superb coverage from the weather to protect your guests and teak deck. Bountiful storage is available with the large lazarette area and engine room access is also found on the aft deck. When walking up to the bow, you will be greeted with full walk-around 15" wide side decks with 33" high stainless side rails.

Above the pilothouse is the extended hardtop which doubles as a boat deck. Equipped with a davit to starboard and tender chocks this platform supports the Rigid Boat Sports 10' tender with Evinrude 30 hp outboard. You will find the navigation instruments, open array, antennas, and express bridge control station all to forward on the hardtop.

Engine Room and Mechanical Systems

The engine room is accessed by a hatch in the middle of the aft deck. Additionally, nearly all of the aft deck is capable of unbolting and lifting off for unrestricted and non-invasive engine access. Once down below the engine room resides behind a latched, insulated door. The headroom and movement space is especially impressive for the
engine room of a boat this size. Along with the convenient placement of components for easy maintenance, routine checks, and service; this engine room is a pleasure to be in. Equipped with two Cummins 6CTA8.3 diesels, 480 hp with V-drive transmissions, this Dettling is not shy on power and can achieve a high cruise of 16 knots and a max
speed of nearly 27 knots.
