I would like to get better at kneeling in this position for prolonged periods of time for canoeing purposes, do you have any suggestions? Is there a range of movements that help or is really just a matter of practicing kneeling in that position.

Per the linked Wikipedia article, "experienced" practicioners can maintain the stance for ~40 minutes. While pop culture can make it appear like a traditional equivalent to sitting in a chair it's really not meant for prolonged use

40 minutes? I can go hours. Squeezing your toes every once in a while and/or subtly shifting weight makes really long sittings more bearable. It's not as comfortable as sitting cross legged ("criss cross applesauce", according to some), but it's OK. It's my go-to position for many seated tasks, including typing this comment.
