On wires and worked with steam*

Thanks again to Paul Quinn for another set of photographs, this time of the newly-installed wakeboarding system thingie in Grand Canal Dock, Dublin, which is to be opened on 9 March 2013.

Wakeboarding, as I understand it, involves dressing up in brightly coloured plastics, standing on a plank and being towed around behind a boat. I don’t myself see the appeal, being more the sedentary sort, but chacun a son gout, as the French don’t say, apparently, although why they’re supposed to know anything about it I don’t … but I digress. The wakeboarding system thingie seems to allow wakeboarding without a boat; it might also require less sea room.

A system was installed temporarily last year; there is information about it here. I don’t know whether that is the same system as has now been installed. You can read the environmental report here [PDF]. Waterways Ireland tells me that

Waterways Ireland has entered into a three year commercial operating licence agreement with Colin Harris T/A Wakedock Ltd., to place and operate a mobile wakeboarding system in Grand Canal Dock.

There seems to be an association between Wakedock and the Surfdock business in the Naomh Éanna, although Wakedock also has its own website.

I asked Waterways Ireland how much it was earning from this; it refused to tell me:

Waterways Ireland do not release license fees charged to individual commercial licence holders as this would be detrimental to our business interest in future license fee valuations.

Waterways Ireland tells me that:

When agreeing the location, consideration was given to maintaining access to the pump-out on Hanover Quay and also access to vessels wishing to enter via the lock gates. No detrimental impact on navigation for other users is anticipated.

Who took the arch? A Shannon whodunnit

O’Briensbridge is a village in Co Clare, islanded between the headrace of the Ardnacrusha hydroelectric power station and the River Shannon. Up to 1929 the river was the navigation between Limerick and Lough Derg (and eventually Dublin), and the bridge itself was something of an obstacle to navigation.

In 1832 the engineer Thomas Rhodes drew a sketch of the bridge with 14 arches, whereas nowadays it has only 12. We know when the seven arches on the Co Limerick side were reduced to six, but it has not been clear when an arch was removed from the Clare side. I think I know the answer; you can read it here.
