Hi Laurie,
The moorings are Leisure only but as far as i know, as long as you are not on the Boat 'permanently' they are the same as most other places.
As for availability i am unsure, i just phoned and was told they could fit me in for a couple of months so am playing it by ear at the moment, hence why i may relocate to Roydon at some point.
I attended the opening day at Roydon last week and was informed the shower / toilet block may not be opening until the spring and find it somewhat bemusing how they can charge the full amount until all the amenities are up and running.
As far as bringing the boat round, well the first day was very much trial and error, i had promised myself to attend a 2 day course but never got round to it for some reason and subsequantly i ended up going broadside twice in the first 4 hours!.
The second day was much easier, although you have to watch the turn into the Regents canal off of the Grand Union as this is a 90 degree through a narrow bridge and i think my passage through it was more luck than judgement.
Have you piloted a Widebeam before at all, or narrowboat for that matter?....i had not even been a passenger on one and it is surprising how fast you can pick it up, just don't attempt to reverse!.
Have you took delivery of your boat yet? and have you bought a Sailaway / Second hand / Fitted out Newbuild?
Just make sure you have at least one other person on board who is capable of bringing the Bow round at tight turns if the situation needs it.
I recommend you have at least one strong boat pole at the ready and always have the ropes to hand for mooring.
More than happy to advise / help as you and i appear to be....excuse the pun....in the same Boat.
