IMO the wingtip foldover method is a little outdated and not really that suitable for beginners, a lot struggle with getting the correct attack angle on the kite so that it sits properly into the wind particularly if it is shifty or gusty , others use too little sand ( kite moves or blows away before they hook in ) or two much sand ( kite wont launch etc... ) I find the best method is the pull around method
ie: run lines out in front of the kite
before walking to the bar, pick kite up and lift it sideways over lines and slightly side on to the wind ( only slightly )
hook into bar and walk back and around ( slowly drags the kite around ) until it is in the leading edge down position with the kite catching the wind ( as opposed to facing into the wind )
check all lines are ok ( last option to make sure everthing is ok otherwise restart )
launch using the water relaunch method ie: pull outer line
Pro's : can be launched off any surface ( boat, grass, sand,( concrete is not great for the leading edge but easily done )
Cons : does drag the leading edge accross the sand ( this is all dependent on the angle which you begin with the kite) get it right and the kite will drag about 1-1.5m get it way wrong and the kite will drag 10+m
I have been using this method for about 4 years in 15knots to 35knots using both Cab Switchblades and 07 Fuels with no noticable damage to the leading edge from either the sand or grass ( one concrete launch has furred up the stitching on one kites leading edge ).
The most critical part is to check all lines once the kite is upside down before pulling the outer line to launch.
There is only one difference between launching the Fuel (C) and SB ( Bow/Hybrid) and that is that with the Fuel you sometimes need to take one or two steps towards the kite once lines are checked and it is ready for launch as this helps roll the kite slightly onto its back ( i fly my fuel on 4 lines so if you have a fifth line a bit of a pull on this should have the same effect.)
For rocky or coral covered beaches I use the fixed object method
ie: run lines out
attach bar using chicken loop to some fixed object eg: sign post, bull bar, tow bar, tree, fence etc....
return to kite pick it up like you are about to launch someone and walk it around and into the wind until it sits on wingtip at the edge of the wind window rest kite and walk back to bar and hook in, reverse the process to land.
This can also be a great way to hook your kite onto a boat..... if you boat launch and want to stop for lunch or drink or smoke etc........ kite to the boat, fly kite to the edge of the window rest wingtip on the water hook chicken loop onto boat and let the kite sit there until you are ready to go again. It is a good idea to depower your kite as much as possible when leaving it in this position as it will make it less suseptable to slight wind angle changes etc....
anyway thats the way i go about it ......might help someone
