Vessel DisplacementYour vessel at departure from Brisbane had a draft of 1.6m and had 5,340litres of fuel, 5000 litres of fresh water and 8 passengers embarked. Last edited by whatthe (20121127 19:50:59) #2 20121127 19:37:07
Re: Vessel Displacementhi whatthe 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. Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #5 20121127 20:34:39
Re: Vessel DisplacementI think I should assume the 1.6 draft is the unloaded draft. so This is now the amount the boat will sink in the water, so reverse the signs Bob You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #6 20121127 22:05:39

Re: Vessel Displacement
Given: So yes, you're right. It should be divided. But also you need to convert the Kg to Tonnes. I change the sign because I reasoned that 1.6 was the unloaded draft. Then load up with fuel and water and the draft should go up. Then it gradually reduces as these get used. So Hope that works out ok. As you can tell, I'm making it up as I go along.
