The Lake Washington Sailing Club invites you to participate in the Iron Butt Race, a 10 mile race from the race deck to a mark five miles down the deep-water channel and back to the race deck. The 10 mile-long course will take an average dinghy about 2 hours to complete in normal conditions. The race is open to any centerboard sailboat or pre-approved keelboat. Our facilities include a clubhouse with large deck, restrooms, a launch ramp for up to 21-ft / 3500-lb boats and a 2000-lb capacity hoist. 2021 Iron Butt NOR Volunteer for the 2021 Iron Butt Race Committee!!!
