1910: Boveney in Thames Villages by Charles Harper.

Boat rollers for small boats on Right bank of Lock. Tel: 01753 862764, length: 149'7", width: 17'10"
1201:  A fishery
1375:  Toll at BaddesbyesLoke
1535:  Lease of a “lock and weir of Boveney and Tyrryshaw”
1632:  John Taylor –

Near Boveney Church a dangerous stop is found
On which five passengers were lately drowned

1770:  Brindley’s Map – Gill’s Bucks
1780:  “Navigation very difficult owing to the sharp turns of the river”

1794: Report of a survey of the river Thames between Reading and Isleworth ... John Rennie (the Elder)

notwithstanding the water is tolerably deep from [Queen's Eyot] to opposite Boveney church, except at the entrance of the Clewer mill-stream yet the turning is so inconvenient, and the head of the Clewer mill-stream so dangerous, that I am much inclined to advise a cut being made from above the bucks across the point to Boveney church ; in this cut there would be a fall of nearly two feet, and the lower sill of the lock being laid deep enough, and the channel towards Gill’s fishing bucks scoured out and contracted, a very good navigation would be obtained from thence to the head of the South Hope.
The great deprivation of water the river suffers by the Clewer mill, is a serious injury to the navigation. It is a pity in a river on which so much trade is carried, mills should be suffered to exist, to the detriment of the navigation.
At the South Hope there are several serious obstacles; and they are of such a nature as render it difficult to give an opinion respecting the best mode of improvement.
From thence to the lower end of the Clewer mill-stream there are several shallows, where I found, even with a small flash which had just been let down, only three feet nine inches of water. These shallows might easily be removed; and it is probable, by a judicious contraction, they might be kept under; but the turnings are so acute, that the navigation is thereby rendered extremely difficult and dangerous.

1834:  “Tom Gill’s Bucks at Boveney Chapel”
1838:  Poundlock built -

Shut in for the first time on November 17 and the cut and poundlock opened at 11am by two downward boats, the Alert and the Ariel, and the Union and one of Mr. Parker’s Trows passing up.  All grounded at each end of the Cut, but by drawing and shutting the weir they all got off in about one hour.

1886:  Armstrong – “A fall of little short of four feet”
1898:  Pound lock rebuilt next to old site.  Rollers built on old site of lock.
1913:  Weir rebuilt

1920:  Fred Thacker –

About Boveney Chapel the main current swings away from the Right bank down to the weir;  and in flood time a veritable maëlstrom is set up where the fierce stream encounters the dead water at the head of the lock cut.  In the high water at Whitsuntide in 1915 my skiff was violently twisted almost completely round against the bank at this point;  the situation is not improved by the huge blocks of cement in the bed of the river.  Bargemen regard the spot as one of the most unpleasant in the whole course of the Thames.

Note that when pulling a boat over the rollers - use a rope rather than pulling on the boat itself.  (The longer the rope used the better - because a long rope pulls the boat sideways less - and on rollers it is often difficult to pull from a central position.  Otherwise you can find most of your effort being used to keep the boat centred on the rollers.)

I wonder what the Victorian preacher is saying?
... and that, brethren, is why Mary has been made to sit at the back
... and if any of you can tell me who made that black mark pointing to the NO ADULTERY commandment beside the altar there, my housekeeper and I would like to hear from you.
