I stepped aboard the comely 75-foot Northern Marine expedition yacht Cheemaun in her marina in Jacksonville, Florida, and instantly realized she was having some work done. Doors and hatches were flung open throughout the boat and I could hear the voices of technicians from Atlantic Coast Marine (ACM) Electronics, a local service provider, in the engine compartment. Casey Cox, president of Krill Systems, ushered me up to the pilothouse, command center for this operation-which was to install his company's custom vessel monitoring system on board Cheemaun. The new cutting-edge Krill Systems would draw data from 46 different sensors that ACM's team was installing throughout the yacht and display it on a single monitor at the helm. "You'd be amazed how many boats don't have anything like this all in one place," Cox said.
