We were traveling from Dagmar's Landing Area South to the 10th St Boat Launch.  Speed was just at hull planing speed, approz 22-25 mph.  As my dad made a slow turn to port to change from a westerly heading to a southerly heading toward boat launch, we hit a floating/partially submerged log.  This log was moored to a piling along with many other closer to shore.  Wehn we hit the log the boat rode up on the logs and spun the boat to port.  THe boat became stuck between logs that were tied tog ther.  Outdrive damge and hull damage was the result.
