Operator sustained numerous injuries, but was able to operate his vessel to the boat launch where he was picked up by EMS and transported to the hospital.  Operator was the sole occupant in the vessel.  No other persons were involved. Alcohol and/or drugs are not suspected to be causing factors to the incident.  Contributing factors are:  (1) Careless or reckless operation due to Operator operating his vessel near multiple obstacles while having his vision washed out by his anchor light, (2) Restricted vision due to Operator's anchor light washing out his vision, (3) Excessive speed for operating his vessel at a speed above that which a reasonable and prudent  person would have operated under the conditions that existed.
