Five people were rescued off the shore of Frankfort Thursday after their boat started taking on water.
The watchstander at Coast Guard Station Frankfort received a phone call from a person aboard a 21-foot boat asking for help.
The boaters were about a mile south of the Frankfort breakwall in Lake Michigan.
The Coast Guard diverted a response boat which was on patrol in Lake Michigan. The Coast Guard rescue crew arrived within a few minutes.
The Coast Guard crewmembers brought four of the five people aboard their boat, passed a dewatering pump to the person remaining on the other vessel in order to assist with the flooding, and then towed the vessel to Frankfort boat launch.
The cause of the flooding is unknown.
The Coast Guard reminds boaters of the importance of having a working communication device, such as a cell phone or a VHF-FM marine radio. A VHF-FM marine radio is the best way to contact the Coast Guard in case of an emergency.
Cell phones should be used as a backup because of coverage gaps, battery life and because most are not suited to work in a marine environment like a marine radio. Most marine radios will continue to work while wet or submerged.
