$100 per day for Coffee? For a 40-man crew to stand watch in the engine room to do the work of a TUGMONITOR. No, we're not kidding. To do the work of one Tugmonitor you would need a 40-man crew in the engine room taking readings every second and they still couldn't do the effi-cient job of a Tugmonitor. . . and it doesn't take a coffee break. Your solid state Tugmonitor automation system responds to pressures, tempera-tures, liquid levels and flow, voltages, current, rpm, or vibrations. It either recom-mends action to avoid a problem or takes action itself. The Tugmonitor is so foolproof it will report its own malfunctions. It doesn't prevent the trouble; it prevents the trouble from causing damage. Tugmonitor is custom designed and built to fit each individual boat's requirements. National Marine technicians provide on-the-spot service during design and installation stages?your guarantee of satisfaction.
