Andy - the campsite has a hair pin bend so if taken poorly you will catch the bottom of your trailer - however our caravan is much lower and has never grounded out if we are careful and take a wider approach
We intend to keep ours on the site and I've often seen dive RIBs bigger than ours up there.
There are moorings - unless anyones knows - I will give Dale Yacht Club or /and Dale Sailing a ring and see what the availability/cost is like - have never had to ask before
There are much flatter campsites slightly further out of Dale plus a Caravan Club site at Dale (Windmill Hill Farm) - still on a hill but no hairpin - more expensive and no pets
We are hoping to pop down at Christmas and/or Easter so will take a photo of the bend and campsite so people can see what I'm waffling about
Hope that helps
