Vessel 1 was travelling south/southeast, jumping the wake of another vessel.  Vessel 2 was travelling northeast, with Vessel 2 to the southwest of the path of Vessel 1.  Vessel 2 could not see the intended path of Vessel 1 as the "wake vessel" was blocking the Operator of Vessel 2's view of Vessel 1.  As Vessel 1 finished its jump the Operator of Vessel 1 turned to port; the Operator of Vessel 2 also saw Vessel 1 at this time and turned to starboard.  The vessels were too close to avoid collision and the port bow of Vessel 2 struck the starboard side of Vessel 1, breaking the leg of the Operator of Vessel 1.
