No progress, I will stop here !!!!
You just simply forget the Scale Factors !!!
This is not a real size boat, is just a model of 127cm LOA
Side hull height is about 7cm and probably masked by the waves....and wind will heat...
all nice but you have numbers for the ballast ?
More confused than before
It is a sailing model of 1mt
Non hull stability expected
Hull surface against wind very low
Wind at 1 mt height totally different from wind at 3...
thanks a lot,
30° is just chosen as maximum acceptable Heel angle.
Hi David ,
Thank you !
If the formula is correct I will continue to use Lift Coefficient "C" = 1
Years ago a friend of mine passed a paper to indicate how to calculate the weight of the Bulb of a IOM sailing model as function of Wind Speed and...
In my opinion one should analyse the two sub systems separately before joing them at system level.
I named the two subsystems "below water" and...
Thanks for your answer, but it is not what I'm searching for.
As explained, watching the COA at 30° of heel, it can be seen that the LCB is...
This is a typical sailing model application where in principle, for a non written Rule, the Fin CG, the Bulb CG and the Hull LCB are all aligned...
the Cardboard pendulum is a sufficiently precise method.
I use it since 20 years on my RC Sailing models.
