The commercial boats I refer to are those built and operated in the days of cargo carrying rather than modern built hotel boats and trip boats, and the point being the one unsuccessfully used for trials was 12'1½ - several inches narrower than those modern boats being discussed in this thread.

Must have built the bridges to allow for a bit of spread ? Link to comment Share on other sites More sharing options...
davidg Posted July 9, 2019 Report Share Posted July 9, 2019 3 hours ago, Tuscan said: Spoke to the skipper of the Tranquil Rose today as we crossed , he says that the blue lias bridge has shrunk to 12’5” (crt measurements) from 12’6” hence they couldn’t get through although previously they could. The bridge which the boat couldn't get through isn't the Blue Lias bridge, it's the one below Shop Lock and this is also the bridge Tranquil Rose couldn't pass through. It was possible to get a pair of boats through the Lias bridge provided that either 1) One of them didn't have a cabin on it and you put it on the outside or 2) One of them had a cabin you wished to remove and were prepared to go into the bridgehole hard enough The 12ft dimension which has been quoted for the Lias bridge is pretty meaningless as it is the arch which is the issue there. Wide beam boats often have to resort to dropping the pound to get through, causing damage to boats moored in that pound and up Kayes Arm. Bickley's bridge has also proved problematic for boats built at Delta Marine in the past: a former Bascote lock keeper had to prevent a hammer and chisel being taken to the arch with the words "Oh no you're ****ing not" when told what was about to happen. I'm told this isn't the first time Tranquil Rose has stuck in New Bridge (not a name in common usage for it, in many years of going over or under it this may be the first time I've used it), they got stuck last year too. 1 Link to comment Share on other sites More sharing options...

Therefore this must be a picture of the one and only journey of Progress on the GU Birmingham line. Maybe Mr Williams can find one of it getting stuck!

David Mack Posted July 10, 2019 Report Share Posted July 10, 2019 I see from this post that the CRT Boaters handbook has been updated with a map showing which waterways are suitable for wide and narrow craft. The map doesn't specify the maximum width for each wide waterway. But it does show the GU main line as wide all the way to Birmingham (and all of the North Oxford as narrow).

Chris Williams Posted July 10, 2019 Report Share Posted July 10, 2019 Press cutting: The motor vessel ‘Progress’ has an overall length of 75 feet, a beam of 12 feet 6 inches, and a depth of 5 feet, and will be capable of carrying 68 tons. It is fitted with a British-Junkers 30-B.H.P. three-cylinder unit engine and runs at 1,200 r.p.m. It carries seven river lamps, a bell, fog horn and has wheel steering and living accommodation.” Link to comment Share on other sites More sharing options...

The gauged dimensions were 75'0'' x 12'1½'' - stowage length 48'6'' - draught light 16.57'' - draught laden with 81 tons 61'0''. The last few tons of a gauging was usually done by calculation and ended when there is less than 1'' of dry side (freeboard) left, but a boat would never load to this depth as its own bow wave would put it at risk of sinking. This would put the hull depth of PROGRESS at between 61'' and 62'' Link to comment Share on other sites More sharing options...

Mine is 14' at the Gunwales and about 1' 6" at the base of the keel. I wonder where C&RTs 'able to navigate' dimension is taken ? Link to comment Share on other sites More sharing options...
