Your craft is fitted out with everything you need to roll deep on the ocean blue. Kick it at the bar, chill on the sun deck and top up your tan on your stag do in Barcelona.
Your catamaran cruise takes in the beautiful Barcelona coastline, which not every tourist gets to see. There'll be plenty of other party people on board, usually including a bunch of other hen and stag groups. Swap stories with the lads and eye up the talent. With three hours cruising and drinking to do, the boys might just get lucky.
Why try to find the party in Barcelona's millions of clubs and bars? Do something completely awesome instead, and make your own celebration on the bitchinest boat in the water. Arrrh!
