Another way to see the city from the water is to hire your own boat! The most popular package these folks have on offer are small motor-powered boats made to resemble little cars, making it rather attractive to the kids! You don't need a driver's licence to hire them, just some form of ID as a deposit. You can cruise through the old town out as far as the shipyards or alternatively investigate the small rivers that feed into the main Motława. Other packages that Boat & Bike have on offer include speedboat rentals, which are much more pricey and some options require you to have a sailing licence. Find them at a little landing pier just down to the right as you pass through the Green Gate. There's a huge range of packages and prices so make sure you check the english website for more details.
