Class M 2020 (Ester-1 & 3)


After several years busy with other classes and not only,
I decided to presents my last plans for the Class M.
Both are using the same basic concept , one is "Wide" and one is "Narrow" ; all the rest being very similar. Was just a matter of "stretching" !
The peculiarity is that the LWL is short on the drawing table as well in the construction, but with a "floating reserve".
Under low wind conditions while the LWL is short also the wet area will be low, but as soon the wind will increase the, hull will start "sinking a bit" and the LWL will increase the length in order to favor higher speed .(Froude Number).
I have assumed 3.5mm variation of the Water Plan height.
My regretted Mentor told me that a Class M will be submitted to a "down force" of 10/12% with a wind capable to produce a 30 of heel.
Of course will be always better to let sailing the model at a heel angle not above 15/20.
Best Wishes for 2020 !
