SEATTLE -- King County Water Taxi staged an elaborate training Thursday to test a new inflatable raft capable of holding 100 people.

The water taxi staff invited reporters, the U.S. Coast Guard and crew members from other boating businesses, including the Victoria Clipper, to attend the drill.

About 60 people abandoned ship, many of them students at the Seattle Maritime Academy.

"We go through the motions in our training drills. We talk through what it looks like to deploy. To actually deploy, have it inflate, and people board it, that's a pretty rare event," said Paul Brodeur, maritime director for King County.

The raft inflated in about a minute. Then, one by one, all 60 or so people slid down a small slide onto the raft.

The county videotaped the entire process and will create a training video.
