All aboard for a thrilling Hen RIB experience! Your high-speed RIB boat will fly along the Thames, surfing the waves at a nerve inducing 35mph, taking in Big Ben, the Houses of Parliament and MI6. Your comic guide will entertain you with a mix of historical tales of the stag and the city as you cruise past the city’s top sites, such as St Paul’s Cathedral. Once you hit Tower Bridge, the music and engines get cranked up and it’s all systems go, pelting through the East of the city at heart-racing speeds before returning safely to the pier.
