However, the four crewmembers involved were uninjured, race officials said.
CT Marine, owned and driven by Wilmington, Delaware, racer Andy Strobert and throttled by Billy Moore of St. Petersburg, Florida, climbed over the rear of CMS and leaped into the air for a heart-stopping moment before flipping and landing upside-down in Key West Harbor.
As rescue vessels and helicopters quickly arrived at the scene, the CT Marine team emerged unassisted through the overturned boat's bottom escape hatch.
CMS's owner/driver, Bob Bull of Melbourne, Florida, and throttleman Randy Scism of Wintzville, Missouri, piloted their boat back to the dock.
