[PUP] Unsailboat fuel consumption

[Ron Rogers]

John,

OK, I'm getting dizzy. Larry, help! And, doesn't a longer boat have a 
greater wetted surface? Is this why naval architects have to know fluid 
dynamics?

| Since weight is directly related to wetted area and wetted area is 
directly

| more to do with fuel consumption than it would in a locomotive for example
| where the rolling friction of the train is nearly independent of weight.
