To be fair we find fisherman and canoeists both as bad as each other.
Not all of them obviously but I've had a fisherman tell me the canals weren't built for boats.
I've had canoes launched practically under my bows and been screamed at to stop IMMEDIATELY. Canal boats can't do anything immediately.
My pet hate is cyclists, not the people who are out for a cycle ride but those who dress in lycra and terrify dogs and small children and treat the towpath as a race track!
Amongst the narrow boat community, I find the fragrant boaters the most annoying.
What is a fragrant boater I hear you ask?
These are usually on widebeams, they are a couple, he is of mature years, invariably pompous and frequently wearing a twat hat (a fake captain's cap).
She is dressed neither for the weather or for boating. Her goosepimples are covered only in swathes of diaphanous chiffon, her feet shod in strappy stilettos. These two navigate their way along the canals cheerfully leaving every lock paddle up, every lock gate open and every swing bridge open!
This leave twice the work for whoever is following them
