Yes, there are other, better options for timing the run back down the Ribble and up the Douglas to Tarleton, . . but only for those with local knowledge, and comfortable with and experienced in working around tides in the lower reaches and estuaries of rivers such as the Ribble. Or with a local boatman or pilot* on board, or on an accompanying boat. NB. * Other than glider or helicopter pilots, . . obviously. So what you are saying I think is that the tactic that CRT espouse for the southbound trip is the only practically feasible one for pleasure boats, since requiring a local pilot would be costly and possible unfeasible because there may not actually be any local pilots hanging around waiting for some narrowboaters to employ them. There is one pilot with local knowledge you could hire. As luck would have it he posts on here. You might have to pay cash though, as he is bankrupt and therefore all earnings paid into a bank would be seized and used to pay his debts off.

I don't think an internet ultracrepidarian is likely to be of any use to anyone.

Unless you are a fan of pink dinghies 😊

If there weren't any local pilots available, I wouldn't have mentioned the possibility of using them. As for the cost, that can be minimised by having a number of boats on passage together with one pilot on the lead boat.

So suddenly you not only have to time the tides correctly, you also need to have a pilot and co-ordinate your crossing with other boats on an ad-hoc basis to keep your own extra costs down. Nothing like simplifying the crossing...

I imagine that GHL over on CanalWorld would be able to recommend a first class pilot.

You'll commence the southbound passage on the incoming tide, as soon as there is some water in Savick Brook. However you will almost certainly ground the boat and have to wait for the water to rise before you can proceed. This photo was taken 10-15 minutes after I grounded and I was probably stuck fast for another 30 minutes or so before I could proceed. So any earlier and you'd just get stuck for longer. Much later and the water level would be too high to pass beneath the Blackpool Road bridge and the water pipe. That's why it's timed as it is. But like I said, you'll see all this for yourself. I've been asked some questions about this photo Ignore the voices. Take the meds.

What about the tactic for going the other way - Savick to Tarlton? Is there a better way of doing that? You'll commence the southbound passage on the incoming tide, as soon as there is some water in Savick Brook. However you will almost certainly ground the boat and have to wait for the water to rise before you can proceed. This photo was taken 10-15 minutes after I grounded and I was probably stuck fast for another 30 minutes or so before I could proceed. So any earlier and you'd just get stuck for longer. Much later and the water level would be too high to pass beneath the Blackpool Road bridge and the water pipe. That's why it's timed as it is. But like I said, you'll see all this for yourself. I've been asked some questions about this photo, and the (mainly) ill-informed tripe that's posted with it. The following notes should answer them, , . . if not, please resend the queries with some added detail as necessary :- The location is the semi-tidal section of Savick Brook, between Lock No. 8 and the rotating half-tide barrier gate approximately half-a-mile up from the Savick Brook's river outfall. The retention water level in the semi-tidal section set by the half-tide gate in the fully raised (closed) position is 3.0 metres (10 feet) above Ordnance Datum Newlyn [ODN], corresponding with a height of 7.9 metres (26 feet) above Chart Datum [CD] on the nearest River Gauge, and a least depth in the navigation channel of 0.9 metres (3 feet). If the half-tide gate had been rotated and raised into its fully closed position, as it should have been on the previous tide's Ebb, prior to the passage of any outbound boats, there would have been a minimum depth of 0.9 metres (3 feet) in the navigation channel along this section of Savick Brook, . . and in the photo there is obviously much less than 0.9 metres (3 feet), . . which means that the half-tide gate had not been raised/closed, as it should have been, prior to the passage of the boat in the photo. Or it could mean that C&RT had not kept the navigation channel in that section of Savick Brook dredged to the specified least depth of 0.9 metres (3 feet). The last but one sentence in the nonsense accompanying the photo states - "Much later and the water level would be too high to pass beneath the Blackpool Road bridge and the water pipe.". This is only partially correct. The clearance height relative to ODN under the A583 Blackpool Road Bridge is not the limiting dimension before or after local High Water, . . there is much less clearance height relative to ODN under the pipe bridge further up the semi-tidal section of Savick Brook. If a boat can get under the pipe bridge, there'll be more than ample clearance under Blackpool Road Bridge.
