Six Flags Marine World 

Every few years, coaster geniuses Bolliger and Mabillard come out with a new, incredible design.  In 1990, they brought us the world's first inverted coaster, Batman: The Ride.  Within a few years, they had mastered the stand-up, and by the end of the 90's, they were producing some of the best hyper-coasters the world has ever seen.  

In 1999, B&M introduced the Floorless Coaster.  Unlike traditional sit-down loopers, a Floorless Coaster has no floor (hence the name).  Riders ride above the track, with their feet free to dangle.

The first park to receive one of these promising rides was Six Flags Great Adventure.   The ride was called Medusa, and was a huge success.

In 2000, many new Floorless coasters were built, including SFO's Batman: Knight Flight, Sea World Orlando's Kraken, SFFT's Superman: Krypton Coaster, and SFMW's Medusa - a near clone of the Medusa at SFGAdv.


With strong competition from Paramount's Great America, Six Flags Marine World had to do something big for the 2000 season.  And they succeeded, with their largest coaster to date - Medusa.

Standing 150ft tall and featuring seven inversions - including the world's first Sea Serpent - Medusa reaches a top speed of 65mph.  The 3,927ft coaster stands its ground against PGA's Stealth - the world's first flying coaster.

From the bottom of the first drop, you fly into the first inversion, a 128ft loop.  This features some great floating at the top, and some nice positive g's pulling out of it.

After the intense Zero-G Roll, you head into the world's first Sea Serpent.  A Sea Serpent is similar to the Cobra Roll, except that you exit the same way that you entered.  This is a very fun and disorienting inversion, and I hope to see more of these in the future.

Medusa is a fun and smooth ride that proves once again that B&M are among the best in their league.  This ride is a great addition to the park, and I hope to see more Floorless Coasters in the future.
