Available from April until the end of October. This slick little catamaran not only offers 40min/30zł sightseeing cruises departing from Przystań Uniwersytecka (departures whenever a group of six or more is amassed), but it's also available for private hire, which we're telling you now is a winning idea for company parties, stag groups, or any group of up to 14 people. Decked out in leather sofas, furnishings include a BBQ grill on the sun deck, a bar with a fridge, karaoke machine, TV and wifi. It's also cleared to poodle around after dark, so put the party lights on and turn the music up. Kind of like a stretch limo on the water, Roger Waters rented it out when he was in town; you want to be like Roger Waters, don't you?
