Wouter,
Some speed you got there singlehandedly !
Yup, goes alright on flat water !
F6+ ?!! that is alot of wind when singlehanding the kite.
Yup, flat water makes it much easier ! Sail on a large lake (in UK terms) in the UK most of the time
BTW, I mentioned my new GPS, I have written a short review for a motoring Site I help to look after, There a a fair number of images, so Iwould not recomend non ADSL users have a look, but it's here if you are interested :
Mini Review of Garmin V, image intensive !
