Water Blind - Mattie entered the channel in the middle of the entry. She took a cast onto the front peninsula. She re-entered the water and held the line across the body of water to the edge of the island before a whistle was blown to get her on the island. Another whistle carried her over the far peninsula and up the middle of the far channel to the exit point, through the tall cover before the two last whistles came to finish her blind.
