Due to my obsession with freshwater fishing my company has invited me
out with a group of clients on a charter boat off Cape Point in Cape
Town.

I know the unwritten rules of etiquette for fishing a small 18 footer
on a dam with two other people but not on a tuna fishing vessel with
7 or 8 people 30 miles out from shore.

Can someone supply me with a few rules that won't leave the charter
captain and everyone else on the boat thinking I'm an inconsiderate
pig?

Don't throw up on the lunch table ;-)
