I was piltoing my 19' sailboat, eastboaund in the Montalke Cut, between POrtage Bay and Union Bay at approximately 7 knots (the speed of most traffic)  A 31' powerboat came past my port side at about 10 knots.  The powerboat was continuing to move towards and in front of my boat, coming within about 2-3 feet of my bow, when the powerboats wake pulled my bow into his stern, which resulted in the damage to my hull.  The captain of the powerboat observed the accident but continued out to Lake Washignton at full speed.
