Operate 365 Days a Year with Greater Efficiency,

Safety and Profits

Until now, ice, bad weather and poor visibility made navigation dangerous, and at times, impossi- ble. A remarkable new break- through called the VIEWNAV™Sys- tem makes navigation easier, safer and more efficient everyday, even in the worst weather with zero vis- ibility, even when ice causes the re- moval of buoys.

This advanced computer-based system combines a detailed, regu- larly updated electronic NOS-qual- ity chart, radar images, Differen- tial Loran-C positioning, and a large video monitor to accurately display all important navigation in- formation. In addition, SATNAV,

DECCA, GPS and DR inputs can be integrated.

Easy-to-use, the VIEWNAV Sys- tem warns of and identifies haz- ards, even in the densest fog; cuts operating costs; and increases reve- nue. Users report it also vastly bol- sters public confidence and crew morale while reducing the naviga- tional stress and fatigue on crew and pilot.

The VIEWNAV System, with its repeatable position accuracy of 5 yards, precisely locates, displays and updates: • Own ship position and movement • Course, speed and distance • Waterway and traffic con- ditions • On & off-station or missing buoys • Detailed navigational data & aids.

The VIEWNAV System combines micro- processor technology with a detailed Elec- tronic Chart, radar images and Differential

Loran-C positioning. Its razor-sharp navi- gational window accurately displays all the information needed to keep the ship safe and on course, even in ice, bad weather and visibility.

Radar display of the same location shows how land images clutter the screen. Identi- fication of useful information is much more difficult without chart information superimposed.

Deprived of visibility by fog, darkness or storm, ships are more apt to collide or run aground. Radar is a great help, but when man fights the perils of nature, he needs a strong edge just to break even.

Countless lives and billions of dollars in damage are being lost due to such tragedies. Now, many can be avoided...


Although the VIEWNAV System warns of impending danger even in zero visibility, it pays big dividends during routine trips. You'll buy it for safety, but it earns its keep by improving operations every day. Not only because it helps protect your valuable property from collisions and groundings. It also increases productivity by allowing your ships to operate more days per year.

Now, even the poorest visibility or missing buoys won't lower earnings by forcing you to drop anchor or take a longer route.



The VIEWNAV System is not like any other navigational tool available today.

It is a unique, easy-to-use interactive computer system which does far more than any previous navigational instrument could. Imagine having a precise Electronic Chart system at your disposal. It provides regularly updated

NOS chart information for each harbor and uses differential Loran-C* to obtain repeatable position accuracy of own vessel to 15 feet. Radar is displayed on the full color Electronic Chart to furnish additional vital information. Analyzing the results in microseconds, the

VIEWNAV System immediately shows in words, numbers and pictures what you need to know to help you stay safe and on course. The large, full color video display constantly updates the waterway and traffic conditions. It's a window to the world that provides greater detail than NOS Charts, radar or loran. The

VIEWNAV System is so precise it helps the pilot guide your ship through the most grueling harbor conditions.




A single glance at the screen clearly shows own ship location in relation to other vessels, hazards, land navigation points, water depth and the position of on and off-station buoys in their actual colors.

Bearing, distance, speed, and arrival time to waypoints and cross-track deviation from channel center line are indicated alphanumerically on the display.

A movable cursor *ln areas where Loran-C is not available,

SATNAV or DECCA inputs can be used.

NAVIGATION SCIENCES provides bearing and range to any other point. Depth contours, Mercator grids, location names and landmarks can be incorporated.


The VIEWNAV System integrates these vital tools into a more valuable and sophisticated system which has greater accuracy, is easier to read, and is less likely to be misinterpreted, even in a crisis situation. The VIEWNAV

System superimposes radar images to verify position accuracy and shows own vessel location in the shape of a ship.

Although standard loran positioning can deviate by up to 30 yards in a day and 100 yards during a year, the

VIEWNAV System's enhanced loran gives repeatable results accurate to 5 yards.
