Munson's "Hammerhead" Hull Provides Stability Munson Manufacturing's alumi- num boats feature a "hammerhead" hull design, with wide chines for- ward to create a dry side, and wider chines aft as well as a deep fore- front to provide hull stability. Munson RIB applications include workboats, patrol boats, and dive boats. Munson has recently combined technology and expertise with American Eagle Manufacturing, and moved its facility to LaConner, Wash.

These boats have use marine grade aluminum extrusions for the outer hull structure for du- rability and longitudinal rigidity. Low-density polyurethane foam is incorporated into compartments under the deck to provide positive floatation. The sponson is made of variable density closed-cell foam and is modular in nature to allow for rapid installation and removal, and a large amount of deck space. Alsafe RIBs are available in mod- els from 18 ft. to 29.5 ft. (5.5 m to 9 m), and custom construction is avail- able in lengths up to 49.2 ft. (15 m). Propulsion options include diesel/ water jets combinations and out- boards. For more information on Ambar Marine, Inc. Circle 152 on Reader Service Card Escort Tugs (Continued from page 60) Last fall Trinity Group's Halter Marine delivered the second of two 155-ft. (47.2-m), 8,000-hp enhanced tractor tugs to Foss Maritime of Seattle. The Garth Foss — which was designed primarily in-house by the Foss Design team with assis- tance from Glosten Associates and Trinity—features a Voith Schneider cycloidal propulsion system and is working for BP. The design and construction of the tugs resulted from a two-year, $500,000 engineer- ing study conducted by ARCO Ma- rine and Foss with the assistance of the Glosten Associates. AWO: Local Conditions Are Critical In Determining Where To Have Escort Re- quirements The American Waterways Opera- tors (AWO), the national trade asso- ciation representing the inland and coastal barge and towing industry, has offered opinions to the U.S. Coast Guard (USCG) regarding the rules which are to issued regarding escort vessels in certain U.S. Waters. In a letter dated February 13, AWO made clear that its "comments are premised on our firm belief that local factors and conditions are of overriding importance in the estab- lishment of meaningful tug escort requirements. We believe local fac- tors are of critical importance both in identifying those waterways in which tug escorts should be required and in establishing performance standards for tug escorts in those areas." AWO believes that once that the USCG has determined that local conditions justify the imposition of escort requirements, it believes that those requirements must be de- signed with the characteristics of the waterway clearly in mind. AWO is concerned by the USCG's stated objective of transferring the perfor- mance standards established spe- cifically for Prince William Sound and Puget Sound to those other waterways which it ultimately de- cides to establish escort require- ments. CONSEIL INTERNATIONAL AgygfA INTERNATIONAL COUNCIL DES MACHINES A COMBUSTION Ol^&SJ ON COMBUSTION ENGINES Prof. Meinrad K. Eberle Dr. George Lustgarten President of the 1995 CIMAC Congress President CIMAC and the Swiss National CIMAC Committee are pleased to invite you to participate at the 21st Congress of CIMAC in Interlaken/Switzerland, May 15th - 18th, 1995 The 1995 CIMAC Congress will reflect valuable suggestions made over the years with a clear priority setting of the themes each day: Day 1 Opportunities and Constraints for the Industry Day 2 Technological Outlook Day 3 Environmental Challenge Day 4 Interaction between Users and Industry A special effort is made to attract the younger generation. A full day, in parallel, will be devoted to computational reactive fluid dynamics (in short combustion) and the latest developments in diagnostics for internal combustion applications will be presented and discussed. A fine evening program and superb optional tours will be offered.
