    Jacques,

    did you just scale the measures to fit Arne's design for your Sangria? Looks okay on a first glimpse.

    Paul 

    Yes

    Good!

    That was exactly the idea with making those master sailplans....

    I have  not access to my pc, but it looks OK to me.

    Good luck!

    Jacques, not a silly question! But the answer is a very clear No. A bermudan mast is not designed to and not able to take the bending loads of an unstayed mast.


    Arne & Paul

    Enclosed sheet 3 . What do you think about cambered panels ?

    Nice evening

    Bonjour Jacques,

    it is of course your decision, and I don't want to push. Your preferred version 1 from Arne will work fine, also. Usually 80% is good enough, if the last percentage points would require a relatively large amount of extra work - in your case, a different mast than at hand. 

    I definitely agree with Arne: Please, at least, build cambered panels ;-)


    Cordialement,

    Paul


     

    Yes , with cambered panels .


    Jacques


    Silly question (perhaps-probably !!): is it possible to use my Bermuda mast by transforming it into a self-supporting mast?

    Jacques,

    The aluminium lamppost seems to settle the matter of rig size. I think you will be fine with that rig (SA = 29.8sqm). I just hope that you make the sail with cambered panels in it, but that is up to you to decide.

    Good luck!
