: I'm not sure the wing paddle stroke would be long enough to do much if used
: on a kayak wider than maybe 22" unless you have really long arms
: (like knuckles dragging on the floor long ).

Exactly my point - and GP, for similar and different reasons, also has such limits to it's effective/optimal application (flared stroke or not - and even more so not). The narrower the better. The difference with a GP in my 21" wide commercial kayak and my sub 19" wide SOF is very noticeable.
