Yes, #narrowboats have tillers. That means that anyone with any experience of boats can steer it with ease. Stand at the back. Push the tiller to the right and the stern moves to the right - and you can see it's going to the right. (Just like the trolleys you get at garden centres with fixed wheels at the front and casters at the back)
Compare that with the cruiser you'll hire on the Norfolk Broads. Many of them have a single level cabin, no wheelhouse, no flybridge - there's bridges with 8ft clearance or less to get under. They'll have wheel steering in the saloon in the bows. That's when things get complicated!
