Non planning upwind 360 is easier than a helitack all you have to do
is and extreme over sheet and sink the tail is almost all that is necessary. No requirement to change your feet while the sail is rotating. Release the clew hand or move it toward the mast hand to release if over powered.
Both ABK and Peter Hart say the Heli should be easy .
ABK pushes the backwinded oversheeted backwinded sail from the clew hand.
Peter Hart suggests it can be done from the Mast Hand .
He is doing it approximately from the Harness Lines.
Anybody try it both ways?
Easy to do this stuff on a big board in low winds but taking to a semi sinker
in high winds not so easy.

Backwinding
Well before I started using rail control backwinded I would just end up going to far downwind and crashing couldn't hold direction or compensate for gusts
in moderate to heavy winds so to me it seems like a necessary part of the
package on boards that one normally planes on .

I learned that way too, Brian. Conceptually sail steering is how it's first taught in light wind, but the sailor's weight is still back on the board. The board is not spun by driving power through the legs. The two ideas (sail steering, waterline work) are not contradictory, and frankly "sail steering" is IMHO the easier (and more fun) concept to play with.

That's not how you turn a backwinded board at all. If you drive the power from the sail into the board you get stuffed into the water. It's about changing the waterline of the board and never being behind the power ("the bull" in ABK speak). The rig turns the board through the mast base, not our feet.


Michael,
When I learned light-wind, non-planning backwind sailing at ABK, I definitely learned (the hard way) about never being behind the power, but I think we learned to steer with the sail. As I recall, Andy added the waterline steering as an 'advanced' measure, which also improves turning speed and ease in other moves, like heli-tacks and upwind 360's. I suck at all of the above, so I cold be wrong.

If your doing this on your windsup or a board that is over 150 liters
in lighter winds then using the upwind rail is not that critical .
The smaller you go in board size the more necessary it is.
Even in the Trictionairy it says keep your weight on the toes or you will
get tossed over backwards. Offsetting your weight to bias the upwind
rail just makes a lot of sense.
Also I now seem to remember the offset feet thing came from a Jason Voss lesson.
