Lively chat this one.
In response to Little Sprite (sorry but I am sure you all have real names). Would it matter if the hire companies sent out DVDs in advance? I doubt anyone would watch them unless they were very keen - the folks on this forum I am sure cover a very small number of the people who cruise the Broads and I am equally sure take care of the hire boats and if not experienced have at least asked for help. The other 90% see it as someone else's property to fix when they give it back.
I have helped loads of boats moor up over the years. Funny one was this summer a day hire boat down at Somerleyton. The front mooring line was just about long enough to reach the post let along tie off!! At least I could shout to them to turn round and come in against the tide.
I also think a lot of people don't realise it isn't like driving a car - yeah you only do 6mph max, but it dont have brakes or go round corners quite the same. They also forget there is 20-50ft of boat behind them that in order to turn will go in the opposite direction. Let alone wind, tide and being cautious of ferries and other moored boats.
Many years ago on my first hire boat experience (and I had been used to boats before) I did a lot of research on forums just like this - tide times, best time to cross Breydon, even refreshing myself on the techicalities of handling a broads cruiser (very different to a smaller boat with an outboard). And still felt I needed to take a lot of care.
On later hires with friends, I can tell you their attitude was very different to mine - oh how difficult can it be to moor a 60ft boat at Yarmouth. One of our drivers insisted he could do it and managed to hit a moored boat on the way in. The following day he was still confident and hit the piling coming off the mooring. He was very complacent about it probably because the boat was hired in my name!!!!! By the way I would NEVER let him moor my private boat!
As for bylaw 21 - never had a problem with hire boats, but private boats - On several occasions have had to take avoiding action because people either don't look or think they don't have to.
If you hire or rent anything - car, boat, house - I can assure you only a very few people will treat it with respect like you would your own. That's from experience of all 3!
I don't have an answer, but maybe put up the excess to deter the rouges, but then does that impact on your business.
I will get off my soap box now!
