I take them as I find them and you get all sorts on the Broads. Catch Phrase from the Film Cool Runnings is "Rise Above It". Great advice and does not spoil your mood. People with Private boats have made a big investment, whether it be a big GP or a small used boat, and like anyone who has invested in something they will be very protective. When you see a Hire boat coming towards you you have no idea if it has an experience crew or complete novices who have just picked up the boat.
Best advice is to take it easy and get used to being able to use the throttle gently and smoothly. Some people seem to have two speeds zero or max and have not managed to smoothly use the Throttle.
Remember there are numpties out there, not that many and they come in both Hire and Private varieties. Just make sure you are not one of them.
