Since we crossed the Ribble Link, we have had a vague feeling of being on an island. We know perfectly well that we are on mainland Britain, but the feeling of being separated from the main network is palpable. This was further reinforced by the totally different lock equipment, and almost every boat we meet is a GRP (glass reinforced plastic) cruiser. They are much shorter and nippier than us, and can get much closer to the edges of the canal without grounding.
