    Hi,
    Do you think it's possible to get some existing mini's laminate schedule?
    I would like to compare it to what I got from the calculations; for example, I got 15 mm of thickness of the bottom, made of solid glass.

    600g of carbon + 15mm of core + 500g of carbon is what they usually put on the best boats.

    :) not much, but it gets you on the other side

    Nico,
    They are actually putting carbon on BOTH sides of the core these days? Amazing... :)

    Wow..that's not much.. I'm wondering what happens in case of crash..
    how could I find the strenght of this laminate, so that I could get an equivalent solid glass laminate?
    Using the ISO rules, I've found 10 mm of thickness in the bottom.

    On these pages you can find a laminate schedule of the Finot/Conq Mini (although it's not the latest generation) for both versions using either glass or carbon fibre. Click on "Construction Amateur" and scroll down a bit. I guess "Zone 1" is the hull, "Zone 2" the deck and "Zone 3" is the superstructure.

    Thanks Olav, I've checked the Finot website..
    but I think Zone 1 is the hull (bottom and sides), Zone 2 is the bottom hull, and Zone 3 is maybe the centerline (keel line).
    Then there is the deck (Zone A) and the livet Zone B.
    I think I will go for a 6 mm solid glass for the hull, 9 mm for the centreline, and sandwich deck like this.

    Nemo, what laminate was assumed when the boat was drawn? I wouldn't want you to overbuild the boat and then be unable to race because it had too much freeboard. If it was designed with a really light laminate schedule, then that is what it will need to perform properly. If the weight increases, then the RM increases, so the rig must be stronger, and thus weigh more, so the hull must be .... You get the picture? :)
