    I also did not understand the calculation, based on actual submerged body. Because Cp is Displacement/(Amax*Lwl)

    I have only one layer. I am just trying to model the hull.

    But there is a window at bottom left corner and it just include ‘layers’. There is not any checkbox.

    Thanks for the answer but I think in free version there is no click/unclick option.

    At this time it worked.
    And also could you please aswer my favorite question about lcb% location.
    You can see at the transom, the waterline is not starting from X-0.00
    So delftship must automatically update the lcb% (In hydrostatic report) location when waterline starting point has changed.
    Regards.

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

    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?

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

    Hello Marven,
    I did not understand what the cwl is.
    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?

    Centlemens very thanks o answers but I know all that you dealed.
    The problem is where will be the location of midship according to lwl. As you know lwl changes when the geometry is changed. I want delftship places miship automatically at middle of the lwl where ever it is. Please answer this.

    As I know the midship must be located at the middle of the lwl automaticaly by the program. How do I know the exact place of the midship then I can manually input?
    This is very important because all of the parameters are arranged to this referance.

    Is it possible to make this round as a constant radius for example 600mm?
