Blast along the River Thames on this 20 minute TOWER RIB BLAST round-trip speedboat cruise from Tower Millennium Pier. Once suited up, sit back and take in the view as you head along the river past the Tower of London and under Tower Bridge. Then its throttle time! Feel the FULL throttle of the RIB's (rigid inflatable boat) 740hp twin turbo engines as you roar along the River Thames towards Canary Wharf & back to Tower in the same fashion... It's a 20 minute BLAST! Thrill in the high speeds and intense wave crashing action at full power all the way back to the Tower Pier. Small-group trips are limited to a maximum of 12 people.
