Aaarrgh... I've just noticed that they've also scratched loads of unintelligible writing into the side of the boat (hadn't noticed before as it was dark when I got home). Now I really really want to catch the little pikeys. Sadly I haven't got a day to spend down at the beach at the moment. Very annoying.
Sorry, I'll stop going on about it. Just needed to vent my anger somewhere!
One of these might help, take your pick it’s all good!
