We used the Texel measured Length Over All when we wrote this rule.
We specifically wrote them in such as way that it would include the FX-one and I-17 (in all versions)
5.30 mtr = 17' 4.5"
This leaves a little margin for the baots and for measurement.
If it was found out that the boats are just a little longer than we'll adjust this rule. The intention of this rule was clear ; include similar boats like I-17 and FX-one.
Texel measure the I-17R at 5.24 mtr. overall. 2 inches to spare.
Some speed you got there singlehandedly !
F6+ ?!! that is alot of wind when singlehanding the kite.
