Washburn & Doughty Delivers Royal Printess Washburn & Doughty Associates Inc. of East Boothbay, Maine, has delivered Royal Princess to Dana Goodell, owner of Princess Yacht Charters of Boston. The sleek, steel vessel, Hull 53 for Washburn & Doughty, measuring 162 x 36 x 10.9 ft. (49.3 x 11 x 3.3 m), was designed by John Gilbert Associates' naval architects and Washburn & Doughty's in-house naval architect, Bruce Washburn. The interior was designed by Bauer Interiors of New Orleans. The challenge faced by the archi- tects was to insure a comfortable trip both in the protected harbors of New England — where the ves- sel joined the Princess Yacht Charters fleet operating from Rowes Wharf, Boston, and the rougher offshore conditions along the Florida coast — where Royal Princess will commence gaming operations this fall. The dinner cruise/gaming vessel was designed from the keel up to accommodate the weight added by gaming opera- tions. For the dinner cruise end of the spectrum, a full l,000-sq.-ft. galley was designed with the capacity to serve 500 passengers. Electrical power is supplied by two, 250-kW 3506 Caterpillar generator sets, each capable of driving the 200-hp bowthruster or providing sufficient power for all shipboard require- ments. On sea trials, Royal Princess reportedly exceeded its design speed of 12.5 knots by logging con- tinuous runs of 13.5 knots, as well as a top speed of 14 knots. These speeds were achieved with a pow- erplant consisting of a pair of Caterpillar 3412 TAs, each produc- ing 636 hp through Twin Disc MS- 520 reduction gears.

In 1993, NNS was awarded the contract to convert two containerships into combi RoRo/LoLo ships to carry U.S. Army equipment, vehicles and sup- plies. The ships will be strategical- ly pre-positioned near areas of potential conflict around the world. Christened on July 4 in a naming ceremony at NNS, Gordon is named for Master Sergeant Gary Gordon, a posthumous recipient of the Medal of Honor. Master Sergeant Gordon won the nation's highest military award by saving the life of a downed pilot of an Army helicopter in Mogadishu, Somalia, in 1993.

The Hydro-Chek diffuser features a downflow design with airflow orifices located in the body, not in the air check diaphragm which is prone to tearing. This design reportedly preserves the flexible diaphragm's structural integrity for a significantly extended opera- tional life, eliminates problems caused by sediment that could other- wise settle in the diffuser orifices, and maximizes the shearing of air bubbles as they emerge from the orifices and turn upward around the perimeter of the diffuser. The positive checking action of the flexible air diaphragm prevents backflow, which is normally due to variations or interruption of the air flow. When the air flow is stopped, the diaphragm contracts and is seated against the diffuser body by the water pressure in the tank. The Hydro-Chek diffuser offers a variety of design features for the marine maintenance crew who may be upgrading or repairing a vessel wastewater treatment/holding system, including: NPT fitting for easy change out; units constructed of non- corroding molded plastic or stainless steel; a diaphragm made of durable EPDM-based rubber that resists both fatigue and chemical attack for long trouble-free service; and the ability to handle air flow for up to 12 CFM each.

A coalescing filter removes condensate and particles larger than .1 micron from the sample line, and a low flow switch automatically turns off the pump if flow is restricted. The McNeill 1900 operates in temperatures ranging from 20 degrees C to 50 degrees C and gas measurement ranges of 0-200ppm or 0-5000ppm of hydrogen sulfide (H2S). The McNeill 1900 runs off of a high capaci- ty, 12-volt, rechargeable lead acid battery and is housed in a fiberglass, NEMA 12 x 10 x 6 in. enclosure.
