The lumber business was going well for the Nickersons, but on December 15, 1959, a shadow fell on their good fortune. About ten in the morning, Sterling Nickerson, Jr., and a relative, Glen Roop, left Sturgeon Bay, Wisconsin, aboard the Bridgebuilder X.; and when they didn’t show up at South Fox Island, a search was begun by the Coast Guard and pilots in private planes. Though the search was continued for several days and was joined by people walking the mainland shores, no trace of the boat was ever found. A day after the disappearance, an oil slick was sighted about 15 miles southwest of South Fox Island but was quickly dispersed by the waves, preventing further investigation. Roop’s body washed ashore in Wisconsin the following summer.
There had been 11-foot waves several hours after the Bridgebuilder had pulled out into the Big Lake, but Nickerson had battled worse than that before. Earlier in the season, during heavy fog, the Bridgebuilder had scraped bottom. She was repaired at the Roen Shipyard in Sturgeon Bay and was sailing back into operation from there the day the vessel repairmen had questioned Nickerson about whether the boat had enough ballast. He replied that he had plenty of heavy chain back in Northport and could place that inside the explanation for the boat’s disappearance seemed to be that the ballast was needed sooner, when the sudden, heavy seas hit.
