The Arch
noun - The Arch is an underwater obstacle at the Aumakua Swim in Maui, Hawaii. The 9-13' deep and 6-8' wide coral arch is located in the middle of the 2.4-mile swim. If a swimmer submerges and goes under the Arch, they can subtract 1 minute off their time for diving through the Arch. Any swimmer who dives through the arch gets a token to show at the finish for the 1-minute "credit". From the first year, it appears by examining results that swimmers "lost" approx 50 seconds by diving through the arch. A scuba diver will be there at the arch to monitor swimmers for safety, in addition to a lifeguard at the surface and a kayaker.
