The Hann 50

Military/Patrol

Hann Powerboats offers the Hann 50 as a fast interceptor, offshore/inshore patrol boat, or fast attack craft. All Hann Powerboats are on the GSA Schedule and available to local, state and federal government agencies. The standard configuration of Yanmar 480hp diesel motors cou- pled to Arneson Surface drives yields a 50 knot cruise speed while only burning 35 gallons of diesel per hour.

Top end is 56 to 58 knots while burn- ing 46 gph. With the standard fuel capacity of 300 gallons, this efficien- cy allows for a range of more than 400 nautical miles (460 miles) at 50 knots. The Hann 50 is available as either an open patrol boat or with a pilothouse for additional protection of crew and passengers. Hann deliv- ered four Hann 50s in the 2010 model year to the U.S. Navy for use as Fast Attack Craft Target Boats. The low profile provides for a low radar signature while the 50-ft offshore deep V hull delivers a ride that reduces fatigue and mitigates shock.

After delivering its first vessel for the U.S. Navy 18 months ago,

Gladding-Hearn Shipbuilding,

Duclos Corporation, has delivered the last of 12, 64-ft screening escort vessels, operated by the U.S. Coast

Guard, with the mission of securing high-value Naval assets in domestic ports. The all-aluminum boat, like its sisters, features a C. Raymond-Hunt- designed deep-V hull, with a CPI

Marine fender system and is powered by twin MTU diesel engines and con- nected to Hamilton water-jets. Top speed is over 30 knots. The pilot- house on a flush deck, with forward- leaning front windows, leads to the forecastle, equipped with a head, gal- ley, berths and lockers. Recessed res- cue wells are located port and star- board at the vessel’s mid-ship. On the foredeck is a mount for a remotely- operated weapon system. The interior is outfitted with Shockwave heavy- duty suspension seats, shock-mitigat- ing floor matting and a heating and air-conditioning system. Equipment includes integrated navigation sys- tems and wireless crew communica- tions and thermal imaging systems.
