As I said, in my computer. Every design is tweaked in all directions thousands of times before settled on. All of them have centers of gravity...
OK, so then your extended boat will need to have added weight forward to keep the LCG in the same relative position..? In my boat I would add that...
Nope, in my posts I have said this all the time. The math and physics must of course be used in the new hull to establish the LCG. What happens in...
Sorry Marmot, but your truism does not apply in this context. Consult a NA...
I think this way of counting backwards from a 0-station is inherited from when drawings were with ink. Today when most of us use a computer, it...
This discussion reminds of an intellectual melt-down. I said that you can keep it, but I am not interested in counting backwards. I start from the...
You can keep it and count backwards if you like, but as I said, the extension is now part of the boat and should be included when you do the math.
I never said the NA gave the wrong answers, I said you were asking the wrong questions. But I can understand if Marmots play with semantics have...
You asked the wrong questions if you wanted to know if the LCG was forward or aft of the desired position after the extension. If he prefer to...
You keep saying this, and there is a tad of truth in it since the LCG moves a little less forward depending of the weight of the extension. But...
Could it be that the Center of Gravity has moved forward...:eek:
It depends if the extension is watertight or not...;)
I think I have given the answer many times by now, the extended hull is what should be considered after the extension. And the center of gravity...
Right, but you need to buy a book and learn about LCG before you start...;)
Longitudinal Center of Gravity = That point at which the combined weight of all the items that constitute a ship's weight are considered to be...
And if it is even further from the transom than before the extension, the LCG has moved forward. Which is what Capt J said and you questioned....
Yep, and if the number from the LCG to the transom has increased more than the number to the bow, we call it a shift forward...
OK, but your station '0' does not exist in the extended boat, it is a new hull and a new position of the LCG, further from the transom than in the...
Do you really believe in what you are saying, or are you trying to play with words instead of facts..? Show me a book where a ships length is not...
This is about adding length. If you not only removed 40 tons of weight, but also took away some length, the LCG may move aft...
