LCB LOCATION

[dssdaad]

I have a book “PRINCIPLE OF YATCH DESIGN” it says the midship section must be located at the middle of the LWL. My question is simply how can I do that in Delftship.

As I know delftship can locate midship section automatically at the middle of the LOA (Non LWL) or We can manually enter the coordinate of the midship section. But at this time we can not know the exact location of the middle of the LWL. If we know both the start and end point coordinate of LWL then we can easilly calculate the half of the distance. Is my question clear?

For yachts the midship section indeed is often located at the middle of the design waterline. Note that this is a fixed location, it doesn’t vary with the draught.

Delftship does not locate it at the middle of the design waterline. It locates at the middle of overall length(LOA). Am I right?

By default it does, yes. You can override this setting hoewever with any value you like.

So for overriding, I need to calculate LWL/2 first. Then I need to find the X coordinate of the starting point of LWL at transom side. Then summing of these two value is the X coordinate of the middship section. Then I will manually change it. But it is too much work(Every geometry change may result in change in LWL). Why doesn’t Delftship make it automatically?

Can you tell me which version you are using at the moment?

2 weeks ago I have downloaded and installed the last version with last update.
