I understand they used to cross the N Sea, but two lashed together.
That is a wonderful piece of work . How old is it?The boat in Dover museum looks even less stable and that was used to transport goods, apparently!

Now added to my "must visit" list!about 3500 years!
The Dover museum is well worth a visit
Not a lot of flotation in a narrowboat. Quick way to build a 60' catamaran though. Isn't that's a journey that wider beamed boats used to take a lot to miss the narrow locks around Northampton or somewhere?I wouldn't. I understand they used to cross the N Sea, but two lashed together.

It's a shame the canal system was never done properly in this country, like the big canals in Europe & Scandinavia you can take sailing boats or ships through. There's just one or two locks that cut the country in quarters due to narrow beams & shallow steps that exclude anything over about a 20-er (7' beam max).
Not historically but in modern times wide beam boats have used the Wash to access the River Nene as the Northampton Arm from the Grand Union Canal to the river was built with 17 narrow locks
(And it was only built at all after the canal company was forced to do so it having been incorporated in the original Act of Parliament)
It's rather more than "one or two" locks*. And it's not just the locks themselves
Even the Grand Junction Canal from Brentford to Braunston, built with 14' wide locks and bridges, wasn't really a wide canal. It was actually built for pairs of narrowboats and thus the width of the channel through the pounds wasn't adequate for passing two loaded wide beam boats etc
It's not a case of it not being done "properly". The terrain, the demand and the finance all worked against the construction of large canals in the English Midlands.
* Separating the nominally wide Grand Union Canal, and thus the Thames, from the wide beam waterways to the North are ...
The whole of the Birmingham Canal Navigations (LOTS of locks!)
or
The Watford and Foxton locks on the GU Leicester section
The latter was always intended to be, eventually, wide beam - at least to the gauge of the Grand Junction mainline (see above)
At the Foxton end, the flight of ten narrow staircase locks was replaced by a short lived wide beam inclined plane but the planned widening of Watford locks at the Western end never happened. The inclined plane proved too costly to run and maintain
The problem increasing the capacity of the waterways is a lack of available water.The problem, as i alluded to, is that it isn't as simple as just widening a few flights of locks (or building parallel wide beam locks or lifts)
You also have to contend with a numerous other constrictions not least, for example, tunnels
Replacing or rebuilding the Foxton incline and widening or bypassing Watford locks wouldn't solve the problems of Crick and Blisworth tunnels both of which would have to be subject to one way working
This has already been a significant issue at Blisworth where, in peak season, there is simply far too much narrowboat traffic to make routine one way working feasible (the canal thereabouts is vastly busier than it ever was in the hey day of canal carrying). Major issues have already arisen with a relatively small number of wide beam boats wanting to use the tunnel, a significant increase in wide beam traffic would cause all sorts of problems
This goes to what i was saying above - it isn't simply that the locks are too narrow. The entire infrastructure of the Midlands canals is unsuited to wide beam traffic
The historic aspect cannot be ignored either but that's a separate and distinct arguement
The Falkirk Wheel links the Forth and Clyde Canal with the Union Canal, which comes to a dead end in Edinburgh. It's also so underused that - last time I heard - they were planning to take one caisson out of use and convert it into a moving visitor centre.I know the inclined plane lift you mention. The old photos are amazing. But look how well the Falkirk lift has worked connecting East & West coasts in Scotland. I know a couple from Norway that used it as a short cut to the Caribbean.
Pater was employed all his working life on the canals, mostly for BCN before nationalisation then afterwards in Scotland.
In my archive somewhere I've a leatherbound presentation document of a project to be put to several of the old canal companies boards of something I think was called The Big Cross.
Basically it was to form a cross of larger canals to take much larger vessels with it's centre in Brum. The four points being (think I remember) Manchester in the NW crossing through Brum to the Thames in the SE then Bristol SW and Newcastle NE. Rationale to shift much larger large amounts of stuff in one go compared with the emerging competition from road transport.
Shame agreement couldn't be reached as it would be a great resource today - look at the stuff the Dutch shift by water.
I can never quite get to grips with the economics. Conjecture: a narrowboat carries 50 tons (2 x 1.5 x 15mts, say).20hp, at 4mph = 25h/100miles, three working shifts. 4litres fuel/hour, so 1litre/mile.
A lorry, 50 tons, with one man in one shift can do 250 miles for probably 10mpg, 110 litres/250m = less than a half litre/mile.
I rather wish this calculation was wrong.
