I can count on one hand the number of boaters who have irritated me, non boaters get to me more often.
I'd say 99.9% of boaters I have met are genuine friendly sorts. Almost all are happy to stop for a chat or help out a fellow boater or boat in trouble and happy to abide by the rules. As on these pages anyone with a boaty problem gets first class advise(usually) even offers to come and help out on site.
It appears a few seem to find problems with fellow boaters with alarming frequency.
We have been boating since the 80's, now retired on our 6th boat, CC'ing for the last 6 years and we are still enjoying every day on the water.
