I passed the the new Yacht Club slipway earlier this morning and there was a lot of "reprofiling" going on with a bulldozer, a tracked shingle/rubble moving vehicle with a bucket and a "Vehicle Marshall" on site, and also the portacabin is back again. The bulldozer was levelling the shingle/rubble to the north of the slipway and the tracked vehicle was moving the debris from the east side, presumably with a view to levelling the easterly side as well to stop the same thing reoccurring with the next strong wind/spring tide.
It is hard to see what can be done to prevent the slipway from being buried every time there is a strong North or N/E wind onto the shore besides taking the existing level area at the top out further and raising the complete ramped surface as it is in a very exposed part of the shore unlike the present life-boat slipway which is somewhat sheltered in the lee of the Orme.
