The kayaker steers his boat with stern rudders mainly. Stern rudder is a typical kayak turning maneuver, when you want to slow down speed.
EDIT: Also, when the kayaker is tilting his boat, he is leaning and not edging his boat. When leaning a kayak, you tilt it to same direction as when you edge a ski. When edging a kayak, you tilt it to its opposite side.
I chose this snow kayaking video because the kayaker has a paddling technique that does not destroy your shoulders. Some other snow kayaking videos make my shoulders hurt already, when watching.
I like the philosophical closing words of the video, too:
May we add freedom to telehiro's list of skiing goals? May freedom even be a shared value across all disciplines of free heel skiing? Further, I guess many alpine skiers share the goal, too. I can feel even the goal of unity in the above words.The only constants that we really have: the water; gravity; our search for freedom; and our instinct to return to the sea.
When skiing Gammes, I have the freedom of moving fast across flats. We have plenty of those here in Finland between our hills, cliffs and fjells.
