How to measure a boats length?

I'm working on something which is hard to describe. I'll just say there are bits and pieces sticking out over the water which do not help make it float. What are the RULES for measuring the length and width of a boat?

This might come into play when docking fees or insurance are a concern. This topic could also come into play when selling a craft or building to a customer's request.

I'll try to list a few things which could help the debate, if you have a link please post it and save us all a lot of typing.

1. Would you include this bow plank in the boats overall length?

2. Would you include this rudder in the boats overall length?

5. Is this RIB as long as the twin stern tips or the hard hull? How about side to side?

6. I can tell you that hovercraft are often listed with hard structure measuments and when the skirt is inflated (on hover) to help avoid a little confusion.

7. You would measure to the bulbous bow (below waterline) of a ship, right?
