Yes 😄 but I do not lie on this matter! At one point I was mildly contemplating resurrection of the boat and outboard, but these days I like my cruises quiet and comfortable - Oakdene was neither!

Note from Bradshaw 1904 Above Bridgwater there is a good trade at all times to the various brickworks within the first two miles of the river beyond the town, but beyond this trade is extremely small... Bradshaw also states there is a towpath from Thorney Mills to Bridgwater (a distance of about 15 miles, but that boats are towed by steamer on the lower river below this (I'm guessing the towpath went no further than Town Bridge, which is a little upstream of this shot) This picture suggests the statement about towing wasn't entirely true... I've never seen the Bridgwater bore, but understand it has a height of 2-4 feet.

Found this picture on a Bridgwater Facebook group and thought it would be of interest, it shows a barge riding the surge behind the bore on the river Parrett , guided only by a man at each end with an oar. Don't know the date but I guess late 19th to early 20th century. Any comments much appreciated To add, the large walls on the left hand bank may be the entrance to the docks, there were wharves upstream of the docks and navigation was conducted many miles inland, although there are few photographs as such trips were infrequent by the early 20th century

Welcome to the forum, but please note you cannot continuously cruise between Keynsham and Bath, it isn't far enough. It's also very difficult to find somewhere to moor on that length that isn't one of the following - occupied, private, or involves mooring to a tree (on private land) with a yomp to get anywhere.

Narrow The K&A is wide but it's two connecting waterways (Wilts and Berks and Somerset Coal Canal) were both narrow - so a lot of coal went through Bradford Lock, the only lock between the two canals, in narrow boats. The Coal Canal Society, when I was chairman, made this argument for the Coal Canal, although we had in mind numerous small basins not 10 miles of linear moorings. We were really selling the idea to Bath & North East Somerset Council rather than the NBTA, and up to a point they bought it - the point at which they stopped buying it was the cost of restoring the canal....

Looking at that you can see why the Aire and Calder opted to pick boats up and turn them over... Any idea of the date?

On a swans neck it is only necessary that both curves are the same, with a C shape the two bends would have to add up to 180 degrees otherwise the tiller would point up or down. Thus swans neck manufacture is easier to get right

My first thoughts are it would help if we knew which locks this is - there are some that are known sticking points and as a result have tried and tested methods of getting through them

Only lock in England which is less than six feet wide? Or perhaps not, one on the Aylesbury branch narrowed itself temporarily...

So, we've got the deepest in the world at Oskemen, thanks to @Greenpen, we've the deepest in England, and probably therefore the British Mainland at Tuel Lane, and the deepest in Ireland (and thus the British Isles) at Ardnacrusha. Deepest in France? Germany? North America? And how does that one at the Slapy dam near Prague compare? And should I be worried that my phone autocomplete knew Slapy dam as soon as I got to the L of Slapy?

I happen to know it was dad's big yellow Ford Cortina estate which carried the family of four along with a car top dinghy and bikes on many an adventure for eight years. This was in the days before manufacturers told you the roof rack weight limit! A year after dad sold it it shot past us on the M6 near Lancaster - we were doing 70 and it left us standing....

Where are you finding the Cows that lay eggs?

I'm not sure I've got any pictures but my first boat, Ripple, had a fixed cross bed at the stern, the Semi-Trad deck having an extended walkway over the bed on one side. This did make the back deck a peculiar (but surprisingly sociable) L shape but it worked, good sized fixed double....

I will admit my thoughts were that MtB was now a starter made from cheese! As far as I'm aware new boats don't have a BSC as they are supposed to be RCR complaint - it's a bit like the MOT on a car. I've never been able to afford a new boat though so I'm not sure on this

If anyone is interested this is the top end of lock 14 today. The bywash has been sealed off and the pound drained. Sealing off the bywash is obvious, I guess draining the pound provides storage capacity should a lot of water suddenly come round the bywash at 15. The gap under the concrete bags looks like a hole, but it isn't - that one coping stone has suffered more than the others fir some reason

Further to this the fall of the other locks on the MSC are given as follows, starting at Manchester: Mode Wheel 13 ft 6 Barton 15 ft Irlam 16 ft Latchford 16 ft 6 The tide flowed to Latchford in 1904 (I think it's kept out at Eastham now) so at high tide for about three quarters of the lunar cycle the tide would reduce the fall. I suspect there are many dock entrance locks that sometimes fall more than 20 feet, I went through Barry Docks and the fall was greater than the funnel height on Waverley. Portishead marina lock is used by inland boats on a fairly regular basis and is certainly deeper than 20 feet - the tidal range in the Bristol Channel means that if a dock were to be commercially viable it needed a deep entrance lock. Whilst all these locks are deeper than Tuel Lane, it's arguable that they're not really on the canal system. I'd suggest that if Eastham has a claim because it's on the Manchester Ship Canal, then Portishead has a claim because it's on a through route between connecting waterways. But neither see boaters using them as their usual route - they're adventures. Whereas there are hire boats that go through Bath and Tuel Lane every week.

The maximum fall at Eastham is complicated, and in part depends on the draught of the vessel. There is probably also a point beyond which they won't work the lock anyway but I have no information on that. The tidal range at Eastham is up to 27 feet, but as the top 5 feet or so is higher than the ship canal this doesn't give any meaningful figure for how far the lock might fall. Bradshaw 1904 - maximum draught on the ship canal was 26 feet, and to get a vessel that deep into the lock the tide had to be nearly level - the canal level was 14 feet above the Old Dock Sill in Liverpool and the dredged depth of the approach channel was 12 feet below. However there was a plan then, presumably carried out, to dredge the approach to 20 feet, giving an extra 8 feet (in other words, a possible lift of 8 feet for the largest vessels). The lower sill was a further 3 feet down, meaning a vessel that just cleared it would lift 11 feet. The lowest ebb tides, the equinoctial spring tide, is ten feet below old lock sill, or 24 feet below canal water level. It's worth noting there's still 13 feet over the sill of the lock. Whether they'd operate it with a 24 foot lift is another matter.

They needn't have worried - almost no-one does the full rise and fall at Bath Deep Lock as filling it lowers the pound above by at least a foot! It's a very short pound and the next lock is of course only half the rise. There is supposed to be a pump to address this, but it hasn't worked for years - they just run water down at busy periods. The entire flight is back-pumped anyway so I guess no one sees the point in repairing the deep lock pump. note - the deep lock was built before the canal was restored, at the insistence of central government, as part of a road scheme that was going to wipe out lock 8. Bath City Council thought the idea the canal would be restored was bonkers but were told to do it. I don't think anyone expected today's level of traffic.

But perhaps not at Ardnacrusha.... 😳 I realise you jest but Ardnacrusha is a shaft lock, the upper chamber drops 70 feet and at the bottom end is a 55 foot wall with a guillotine gate at the bottom of it! I can think of all sorts of logistical problems trying to rope a boat through...

The MSC locks are around 14 foot 6 each (Except Eastham, the tidal lock, which is only a couple of feet) Tardebigge's claim was always false - it isn't that deep at about 11 foot 6. The 14 foot claim was made by de Salis in Bradshaw 1904, but is incorrect. At the time Aberfan was deeper anyway, a two-rise with a total lift of 29 feet.

Having personally pushed hard for the RCHS archive to get off the ground it's really good to see it getting used and giving value! I'll feed this back to the Council and Managing Committee. @1st ade did a fair amount of the behind the scenes work too.
