Here in Ireland
, and in the UK, they are called "Patent Slips", at least that was what what they were called 100 or so years ago when they first started to be used in boatbuilding yards. There are two boatyards
in Oldcourt, near Skibbereen, County Cork, where I have frequently seen large fishing
vessels, 80 feet or more, hauled out for routine maintenance
. There is a disused one right in the centre of Baltimore
village, not too far from Oldcourt. You can see all these on Google
Maps, sattelite view.
Those ramps which slope down into the water for launching small boats we call slipways, or slips, for short. Note, we do not "slip" a boat we launch it. If there is a lot of green weed on the slipway at low water, we need to watch our step, or we might slip
A further difference in boating
language on this side of the pond is that in marinas
we tie our boats to pontoons, a dock being an area of water enclosed by walls and accessed by lock gates, where vessels can stay afloat while the tide is out, also called a basin. If you look at a map of Liverpool or London,for instance you can see a number of these.
