Engineering Science and Drag calculations for a simple dinghy

[middlj]

1. The problem statement, all variables and given/known data

I have to compile a report for a project on the science behind a boat. Its a really open ended aissignement, I have no ideas where to start or what equations to use.

I need the boat to go 20mph and therefore calculate what engine power I will need to make it reach that speed.

In addition I need to do some buoyancy calculations.

I'm sorry if this seems vauge but its all i have.

Any Help or guidance would be greatly appreciated!

Thanks in advance.
