RedactedNarrative: Driver #1 had picked up a friend at the dock and proceeded out to meet with the driver of vessel #2.  Driver #2 was circling quickly and not watching as driver #1approached.  Driver #1 attempted to slow down as #2 circled and was unable to stop.  His jet ski rode up the starboard side of jet ski #2 and struck driver #2 throwing him into the lake.  Both drivers were wearing kill switch lanyards which stopped both vessels.  Driver #1 jumped into the water to assist #2 and got him on to the jet ski.  He drove him into shore and assisted him onto the dock.  Adults came out from the house and called 911 and Leland EMS transported him to Munson Center where he was treated.  His injuries consisted of cracked ribs and contusions.  Both drivers were wearing their life jackets.
