One thing I have noticed with fendering suppliers is that they sometimes seem to be selling Wilks products under a different name but at a higher price than Wilks themselves.
Flat batteries and full bilges are the things that worry me the most tbh, although luckily out of the three boats currently in our family two are currently sitting on the hard and the other was given a good coat of looking at just before lockdown so should be ok.
I think that I would book myself in for an extended stay at the Altnaharra Hotel in Scotland, situated along the A836(a single track with passing places!) in Lairg.
