| Worse still, because the river dries out for most of the time across virtually the whole of this stretch [other than a trickle in the middle], the differential in height between boat and pontoon from afloat to grounded, demands that they need to be roped with sufficient slack to accommodate that difference. As a consequence, when the tide is running hard - both incoming and outgoing – the boats will be swinging at exaggerated angles relative to their pontoon, with most pressure being at the outer end of the fixing to the pontoon fingers. Adding to that the fact that the fingers will not be extending the length of the longer boats, the fingers would need to be firmly fixed to large piles driven into the bed at the end of each one, if they are not to be wrenched off their hinging to the main access pontoon. It really is extraordinary that they have come up with this layout in contrast to every other mooring installation on the tidal Thames, both near and far. Manoeuvring in and out of the berths at anytime other than the slack at the top of the tide [a very narrow window] would also prove an interesting feat. |
