Vessel 1 was returning from North Perry/Townline ramp after stopping to drop several passengers off when the Operator of Vessel 1 stopped Vessel 1 approximately 3 miles west of Geneva Marina and turned the motor off so that one of the Occupants could swim.  Vessel 1 was not anchored at this time but left adrift.  The Occupant/Victim donned a personal flotation device (PFD) and exited the rear of Vessel 1 through the stern door and onto the swim platform.  As the Occupant/Victim descended the swim platform, she lost her balance, subsequently releasing her grip on the swim ladder, at which time her lower left leg caught in between the ladder rungs, fracturing her lower leg.  The Operator and additional Occupants aboard Vessel 1 assisted the Victim back onto Vessel 1 and contacted emergency services on their way back to Geneva Marina.  Emergency services met the party at the marina, where they stabilized the Victim's leg and transported her to Geneva Hospital.  Doctors confirmed that the Victim's lower tibia/fibula were fractured.
