MACHINERY INSTALLATION

 
The vessel is powered by a 48 HP Westerbeke diesel, 55D-Four with a continuous SHP output rating of 48 HP @ 2600 RPM mounted to the longitudinal stringers on aluminum beds. This is coupled with a Zf 25A hydraulic transmission with a 1.93:1 gear ratio. The gearbox is joined to a 1 1/4″ diameter Aquamet driveshaft through a DriveSaver coupling. The fuel filter is Racor, USCG approved.

The driveshaft is carried to the stern bearing in a 5′ x 3 1/4″ O.D. shaft tube sealed with a standard speed P.Y.I. pack-less shaft seal to turn a 16″, 3-blade, bronze propeller.

Control of the engine and gearbox is through cables from a single lever control mounted on the top of the operator console. Engine start/stop and monitoring is by a Westerbeke, panel including ignition, engine stop, oil pressure, coolant temperature, tachometer, and attenuator panel with visual and audible alarms.

Raw cooling water is supplied by a single 1″ bronze thru hull with screen, a UL Listed bronze seacock, connected to a bronze strainer with a stainless steel basket.

The single exhaust, from the 3″ diameter mixing elbow on the engine, is a Centek Fiberglass Wet Muffler, marine wet exhaust hose withstainless T-bolt clamps. Running aft, solid FRP tubing is used to connect the muffler to the Centek thru hull exhaust fitting, with rubber flapper valve.
The fuel tank is a single, 49 gallon tank, aluminum construction with a black coating on the exterior, 2″ fill, 5/8″ vent, 5/16″ pickup, 1/4″return, from RDS Mfg. with USCG Certification. Installed on FRP pads on center, between longitudinal stringers, under the deck aft. Fill and tank are electrically bonded.
The 40″ vertical tiller pivots on a 1″ stainless waterproof bearing with an 8″ arm. The tiller and 10″ rudder arm are connected by a pushpullcable with 3/8″diameter spherical rod ends and rated at 150 lbs. push, 1000 lbs. pull, with positive rudder stops at helm and rudder post.
The electrical system is a standard 12 volt marine system using a Group 31 wet-cell marine battery, with the positive wired through a batteryisolation switch to the engine starter and a fuse panel in the console. Battery cables to engine and isolation switch are 2 AWG marine assemblies with a 10 AWG connection to the fuse panel and negative buss. All wiring is marine grade minimum 14 AWG, copper stranded with 105°C insulation, UL listed, and color coded per ABYC Standards. All alarms are located at the operator’s console. All wire connections are appropriately sized crimp-on rings, with adhesive, waterproof shrink tube. Wiring is labeled for ease of maintenance. Two waterproof rocker switches on the console activate the running lights and the courtesy lights in the cockpit.
Fixed System – The single, rechargeable, manual/automatic BC extinguisher, using 125 cubic feet of HFC-227 clean flooding agent, is installed horizontally inside the forward end of the engine cover with a manual discharge cable mounted on the operator’s console. The Fireboy Xintex, Inc. Model #MA2-125 is coupled to an automatic engine shutdown system, Fireboy Xintex Model #ES-3000-1, indicator panel mounted on the console with discharge alarm and light. Fire Extinguisher – 2.5 lb. Class B-1, dry chemical agent, rechargeable with gauge, mounted on the starboard side of the operator’s console. Fire Extinguisher – 10 lb. Class B-2, dry chemical agent, rechargeable with gauge, mounted in forward locker. Emergency Fuel Shut-off – Manual pull cable with tee handle on the console, adjacent to the fire pull, connected to the fuel tank valve. This valve is accessable under the aft hatch. Three 12qt buckets.
Life Vests – Type 1, with reflector patches and name of vessel, 25 adult and 3 children. Storage is in two locations, the majority in an opening deck box on the centerline just abaft mid-ship, the balance stored in the bow. Ring Buoy – Type IV, 20″ white, with the name of vessel, and integral web straps and grab lines, secured to the vessel with 60′ of 3/8″ UV resistant polypropylene line. The automatic floating strobe light sits in a stainless bracket adjacent to the ring buoy and attached to the buoy by a 6′ lanyard. Signal Horn – Portable, air powered.

Frequently Asked Questions

What is the deck height or freeboard of a DUFFY-26 Launch?
The DUFFY-26 Launch deck height or freeboard is 27″ aft, 28″ midship and 45″ at the bow.
What stability tests have been done to the DUFFY-26 Launch regarding the USCG weight requirement?
We have completed both the mathematical and physical stability test for the DUFFY-26 Launch for the new USCG #185 weight requirement. These tests were performed by the US Coast Guard, Farrell & Norton Naval Architects, and David White, PE. In addition, the DUFFY-26 Launch has undergone these tests twice, first for our Standard yacht club launch and a second time with a full canopy enclosure..
What type of transmission is in a DUFFY-26 Launch?
In the launch business, a solid transmission is a critical part of the operation. the DUFFY-26 Launch comes standard with a heavy-duty marine transmission, either ZF hydraulic or Borg-Warner velvet drive.
Can I get wheel steering or tiller steering?
Yes, the DUFFY-26 Launch comes standard with tiller or wheel steering. Traditionally, many yacht clubs like tiller steering for ease of operation but a USCG certified hydraulic steering system is also available.
How is access for daily maintenance on the DUFFY-26 Launch?
The DUFFY-26 Launch is made from molded, composite units greatly reducing screw holes and joints. This style of manufacturing allows for easy cleaning and up-keep of the fiberglass. In addition, the systems can all be easily reached through the engine box area.
What about sea-keeping in rough conditions?
The DUFFY-26 Launch is built on a commercial Downeast lobster boat hull so it is strong with a full keel and skeg providing excellent tracking, sea-keeping, and protection of the propeller. The DUFFY offers a soft ride only a built-down hull can provide
