I am making some progress.
First of all,I am now very comfortable on the Aguera board and Spotz foil. I tried my race board yesterday and found it slow and bumpy. I think I am faster on my foil than on my raceboard upwind and downwind now. Of course I am in flat water and steady wind here on Cayman Island and it may be harder when I get back to chop and waves.
I am finding the touch down jibes pretty easy at least for anyone with raceboard experience. I have made a few touch down regular tacks and they are not too difficult either. But doing transitions while foiling is far beyond me.
On the jibe I pull my back foot out and put it in front of the back strap as I start heading downwind. Then I touch down on the water and do a quick foot switch by putting my back foot in the empty front strap and quickly moving my old front to the back of the board. I have already started my kite down loop by then. After that I just hold on and hope to keep my balance as I turn. Generally I try to get my new back foot in the back strap before I start foiling again. If I was better I would of course do my foot switch quicker and never come down off the foil.
For a regular tack it is just like on a raceboard. I made a few but now I am working on roll tacks mostly... I find them very difficult so far. I have been told that you can start doing them by touching down and then later learn to stay up on the foil.
I highly recommend a warm water location for learning.
