RE: Low End - iSonic 101 and 111 - Q for Ian Fox
It's always difficult to define low end planing thresholds accurately, as there are many important variables involved. One of the critical variables is the rider style/technique/energy/determination to get any board going in a given set of conditions.
It's the difference between an "active" rider style (good pumping/planing skills) and a more "static" rider style (stand there and let rig/board/fin pull you onto the plane).
Both styles are very valid - and very common.
In summary, a rider with strong active style will reduce the low end planing gap between the 101 and 111, whilst a rider enjoying the relaxed (non active) style of ride will find a larger gap between the 101 and 111 (especially around 7.5m conditions)
A rider with really good active style could likely narrow the gap between the 101 down to 1-2kts (in the critical 7.5m planing threshold range); the rider adopting a fully "relaxed" style to early planing may find a 2-3 kt difference at that wind range.
(again, there are many outside variables - like water state flat vs choppy, and "quality" of wind in this range that have real influence on any hard numbers)
With a rider wight of 74kg, and moderate skill/energy, you should plane up pretty early on the iS101/7.6mTR3 - and the question deciding between the 101 and 111 could also be influenced by top end control/range.
