I recommend this trip . It costs about £5 and lasts two hours. There are two Galleons that operate from the waterfront in the Old Town. You travel down river and see the huge Shipyards and the massive boats. It stops at Westerplatte and you can get off for a look around and the next boat will pick you up in an hour. We did not bother. You can buy snacks on the boat and a guy on a guitar played on the way back. All in all ,it made a really nice afternoon.
