Not only that, but:

That's where the cafe boat (Moonraker?) used to be - I last saw it in Lincoln. My favourite mooring in Slawit right next to bakery, brewery and dog walks and handy for the best pub, the Commercial.

Isn't all this nearly a fortnight too late?

Yes, but....... You have to call her by name before she replies. I got one for Christmas a few years ago and when I recently dug her out I realised I'd forgotten her name. Then when I remembered it and tried to listen to any BBC station she went wittering on about having to link my BBC account to a profile on the Alexa app on my phone. I don't have a smartphone. I'm sure I could listen to BBC stations without all this when she arrived. Bloody woman. Help! I think I've been left behind

I've been twice up the Pocklington, the second time up the newly opened stretch to Bielby (although the arm to the village was not navigable). It was real outback boating - described here

Although not a liveaboard, in several years of cruising all over the country between March and October, and stays on the boat in winter, I never failed to find a sufficient supply of dry wood, either fallen or (preferably) standing dead. I was fortunate in my winter mooring at Sowerby Bridge, in that the Calder & Hebble seemed to have plentiful resources of suitable firewood, although I did manage to find enough in most other areas as well. It did involve a constant lookout for firewood, but that became (and still is at home) second nature. On the boat and here at home:

Of course I realised what the original notice was on about. I was just picturing a 60ft boat proceeding diagonally along the HNC. 😀 You'd need a bow thruster of.course,

From the latest CRT notice about the numerous obstacles to navigating the HNC: Huddersfield Narrow Canal Marsden Flight Information Boaters wishing to pass through the Huddersfield Narrow Canal are restricted to 57ft in length (Narrowboats of no more than 60ft in length can pass through diagonally)

This just begs the question why on earth would anyone have done this?

I had only one crew member, and her paws couldn't grasp the wheel or reach the box.

Just to tempt the OP further, a couple of pics. It became really important when approaching a lock to see whether it had a box or a wheel.
