Missing return statement

there is an error on the last closing bracket that says missing return statement, but i dont know what its asking me to return

public PedalBoat findPedalBoat()
{
PedalBoat myPedalBoat = null;
// loop through list of boats
for ( int i=0; i < numPedalBoats; i++)
{
if (thePedalBoats.get(i) instanceof PedalBoat)
{
PedalBoat myPedalBoats = (PedalBoat)(thePedalBoats.get(i));
if(myPedalBoat.getHired()== false); // string compare
{
System.out.println(myPedalBoats.toString());
}
}
}
// return PedalBoat;
}

You should return PedalBoat as you had it.
