If you decide you wish to go 7.550 meters draw.. Then you will need to increase the prod length. 1.4-18 meters from stem rather than the 0.8 meters your now setting in concrete..
<br>There are some advantages in increasing prod.. The "wing" becomes low aspect and is less inclind to collapse due to changes in angle of attack..
<br>
<br>As for breaking expensive masts.. If I can hold up a 24 sq meter mast on the tip of my skiff (dia 2.5 mm) I14 hold 27 sq meters on smaller tips we just use uppers to handle the downhill forces... Im sure the mast makers can design a layup for the 16 mp.. Older rigs just add a second diamond above the hounds to take the kite..
<br>
<br>Finally If Wouter one sets the kite with its sail area not behind the rotation point you will be surprised how light the sheeting forces are.. I have sailed solo on a skiff with 24 sq meters.. With a lot less righting moment and stability than this new class.. So 18 and 21 sq meters shouldnt be a problem..<br><br>
