The megayacht Magnifico, built by Christensen Yachts, Features Lo-Rez Soft Mount systems
Lo-Rez " Soft-Mount" Systems Are
A Sound Choice
For Wide Range of Vessels
Beginning with its patented steel- spring vibration isolators in 1956,
Vancouver, Canada-based Lo-Rez
Vibration Control Ltd. has since de- veloped and marketed widely its lines of flexible couplings, shock mounts, torque limiters, crankshaft dampers and "Soft Mount" systems to the marine industry.
Steel-spring torsionally soft flex- ible couplings have been extensively used between diesel engines and gear boxes for the effective and pre- dictable control of torsional vibra- tion since 1960.
Lo-Rez steel-spring vibration iso- lators, long a "must" in shipboard auxiliary generating plants, are com- ing into wide usage in propulsion engine systems, including direct drive engines of 2,000 hp/600 rpm.
When these isolators are used in conjunction with the torsionally soft spring couplings and HLF (High
Lateral Flexibility) couplings, a very high isolation efficiency treatment of noise and vibration is available.
This combination, as used in the M/
V R.B. Young, is particularly useful in hard-mounted gear applications.
The more common Lo-Rez "Soft
Mount" system, utilizing the elas- tomer RT type sound-attenuating flexible couplings is now is use in over 160 propulsion applications, ranging from stealthy research ships, survey vessels, Coast Guard cutters, U.S. Navy patrol craft and mine countermeasure ships to tugs, dinner/excursion boats and luxury yachts.
Lo-Rez, for example, has sup- plied systems for six of the eight megayachts delivered by
Christensen Yachts over the last three years. When engines and gear boxes are integral, the two units are supported on BR4-TLS thrust-ab- sorbing isolators and the noise-at- tenuating RT couplings are posi- tioned aft of the gear boxes.
With steadily growing emphasis on the requirement for environmen- tal noise and vibration control, Lo-
Rez—now marketing some 75 per- cent of its product lines in exports— is looking forward to very strong growth, according to Ted
Spaetgens, the company founder and president. Mr. Spaetgens be- lieves that although Lo-Rez is heavily committed to its industrial business which includes the grow- ing seismic market, he feels that the marine industry will continue to hold the largest potential and challenge.For free literature detail- ing Lo-Rez " Soft Mount " systems and other noise and vibration con- trol products.

NavGraphicXLGPS
The brightest idea in navigation just got brighter.
The NavGraphic revolutionized navigation by automatically plotting your exact GPS position on a real NOAA chart. It's like watching your boat's progress from an air- plane overhead. You can zoom in for precise maneuvering or zoom out for an overview of your entire voyage.
Expert fishermen love it because the charts are complete with depth lines so they can follow bottom features looking for fish. Beginning navigators love it because there are no numbers to translate and no calculations to make. It's the most direct navigation tool ever developed.
Now that revolutionary product is even better with a brighter, higher-contrast display in a new slim-line design. The new dis- play makes it easy to read under any lighting conditions and its new price makes it even more affordable.
The NavGraphic XL—it's a whole new way to look at navigation.
