Common Etiquette screw ups for novices

[Makr0]

Hey All

I am one of the many aspiring new sailors, keen to get a boat and start cruising.

Like all enthusiast communities there seem to always be things that new people do that slightly annoy to full on piss the veterans in the community off.

What are some of the common ones? Feel free to rant a bit if you need too, they make for good internet.

Thanks
