The early spring fire at a Grand Haven marina has been ruled accidental.
“There have been no further conclusions made,” said Lt. Joe Boyle of the Grand Haven Department of Public Safety.
A Grand Rapids man was seriously injured in an explosion and fire at North Shore Marina, 18275 Berwyck St., on March 23. Michael Rosencrance, 56, was taken by ambulance to Spectrum Butterworth Hospital in Grand Rapids after the incident.
Rosencrance's family declined to release any information on his condition. His attorney did not return a phone call by press time.
Police said Rosencrance was performing electrical work on a boat in a boat storage building when he ignited a torch and an explosion took place. Although injured, Rosencrance was able get out of the building on his own.
Three boats were extensively damaged in the explosion and resulting fire. A hole was also blown through the wall of the building.
Other boats inside the large storage building were damaged by smoke and water.
The hole in the building is covered with plywood.
Only a handful of boats were still inside the building this week. One of them is a large, soot-covered vessel.
Marina owner Chris Lisowicz declined to comment on Thursday.
