hi whatthe

Let's try to get some formulas to get all this information under control.

(a)

As the distance is in nautical miles and the speed in knots, the journey time should be straight forward.

T will be in hours.

(b & c)

These will be in Kilograms.

dictionary says draft is the distance from the water line to the bottom of the hull.

So as the weight goes down, the boat will float more so the draft will go down.

That's for fresh water.

Now boats float higher in salt water so I'm guessing that for a salt water harbour you do this calculation and then divide by the sd.

I've never done a draft question before so I hope this is all correct.
