Agree with Carldelo. Lots of lift when a GP is used proficiently.
@Allan, Lawler makes the interesting remark in his masterclass video that a wing is a “dumbed down” Euro paddle, saying that water can only spill off one edge so you only have half the work to do with regards to avoiding flutter (his words). Canting a GP gives a similar effect.
GP works very well with a “wing-style” torso rotation stroke. That said, the extremely low volume skin-on-frame kayaks, such as found in Greenland, simply don’t allow your knees to rise and fall (required for strong lower body rotation (e.g. butt rotating in the seat)), so kayakers there typically perform more of an abdominal crunch stroke, where you press your opposite thigh against the masik (curved deck beam) and your torso rises and falls (bends forward). You just don’t see much torso rotation in Greenland, which surprised me on my first visit. My initial impressions upon seeing the crunch stroke for the first time are on the Qajaq USA website at http://www.qajaqusa.org/Technique/Greenland_technique_from_the_source.html .
Many paddlers outside of Greenland use a crunch + rotation, essentially a hybrid stroke, combining what they learned from different sources. This makes it challenging to teach Greenland forward stroke technique, as it varies with kayak volume / preference. I rotate when I can, but some paddlers like Maligiaq Padilla will always “crunch”. For myself, low volume = crunch. high volume = torso rotation.
