If the info in this story is correct this Steve Snyder guy can haul ass in a 12' boat. Sunset on the 3rd was at 5:53. This gives him a 4.5 mph average if he got to South Manitou by dark. Winds were calm, but the temps were around 35, water temps around 35-BuRRRRR This guy has more than luck working on his side!!! He did beat our record for "earliest crossing to South Manitou" by over two months, but I think he gets the Weenie Award for the return trip!
The Ranger at Sleeping Bear Dunes was right on the money and I know of a great 17' boat that would have been perfect for this adventure.
