    Hello Jurgen,
    It looks like to be matter of “Cornigiotto” some reports were published in the Nautica magazine recently. Nice boat, indeed I asked the publisher/reporter about original drawings but no answer..??!!

    Anyhow you look like to be another good expert of Delftship and may be you have some suggestions how to manage following issue:
    By modeling a boat with exact same ends like the canoe, I did model first only half boat hull and then I mirrowed it. The design looks fine but the hydrostatics are not correct!
    Do you know by chance whether there is another correct way without having to model twice the same bow?
    Thanks
    Adriano 🙂

    Thanks eb,
    Yes, most probabily the way I set the question it could be somehow missunderstood.
    Anyhow I got it allmost right now.

    Yes Jayoh,
    It looks like that the starting base makes that difference!
    My concern now is: anything modeled by inserting new control points and faces will have double sq. area?! It can be a big headache for me to go back and check it!!
    It would be good to have some words from the administrator this regarding.
    Have a nice day

    HI Jayoh
    I simply created the sails adding new control points and new face.
    This could be the reason why the symmetric box is not activeted, as you say only parts started from cylinder, box or keel etc. have this option.
    Anyhow just find out that the sails had two interior edges!!?? do not know why so by deleting one the sail area is reduced by 50%. Still need to go down another 50%
    By removing the contol net also nothing has changed.
    Thanks

    Hi Jayoh,
    Thanks for yr comments.
    I was hoping to get some feed back from Marven to find out why Symmetric check box in my case is not reacting at all.
    I may miss something in the setting?!
    The rig in question is Gaff sloop with approx. something over 100 sq mt sail area and the data shown by the systhem seems to me to be even 4 times the real one????!!!
    Do you have any idea what could be wrong?
    Thanks
    Adriano 🙂

    Hi Marven, glad to hear from you again.

    Well… I mean the layer properties within the “Design Hydrostatic report” which is also showing the the square area .
    I assume mainly it’s matter of symmetric but I cannot find the tool to disactivate it?!
    Strangewise the one box next to (my) sail layer properties is not working?!
    Thanks for any tip 🙂

    Hi Dida,

    The data from the hydrostatic report shows far more than double the real sail area?!

    -sails are designed perfectly on the central line
    -to tick or untick the symmetric box doesn’t show any changes indeed this tool is not working with the “sail” at least in my case?!

    – meanwhile I got the way (thanks to Mike) how to compute the Center of effort 🙂

    By putting all sails, or the ones you want involve, on one layer you have the VCG and LCG sothat we can easily locate the CE of the sails.

    Unfortunately the sail area shown on the hydrostatic report still gives a wrong measurement?! :angry:

    Well,
    keep pushed both left botton of yr mouse and ctrl, go over with the cursor anywhere on yr model you want to be highligthed,
    all control points/lines will be selected.
    I do not know any other better option!

    Hi Rurudyne,

    May be you have a solution to my followings question marks?!

    A – I found out that the sail area data shown on the hydrostatic design report by far is not correct
    what do we have to do to get the correct sail area?

    B- to locate the Center of Effort is there any system available on DS?
    Appreciate any help.

    I am about to locate the center of effort do you know the way how to get it on DS

    Hi
    When you right click on the screen you get “deselect all” tool.
    Is that one you’re looking for?
    To select all it’s not a problem isn’t it?

    Hi Poulsen.
    Personally am still using DS free for learning process, sofar I know this version has limted access to the main extentions, which are important when you professionally design a boat/ship .
    My suggestion is, you start the free version (doesn’t cost anything!) then you’ll soon realize on yr own what kind of limitations are there.
    Have fun with DS 🙂

    Hi Sergio,
    Thanks for yr comments.
    Yes, I was afraid that building another cylinder around 🙁 is the only main option left.

    Thanks Dida,
    Yes it looks like that sofar!
    I divided the half circle into 3 sections which I extruded each one in its axis direction and adjust it by hand.
    It’s a tedious job and at some stage difficult to master and I believe, at least in my case, it will be not that clean.
    I hope there is another way which the administrator could suggest.
    Let’s hope it!
    Adriano
