Any info would be great. I am thinking of undertaking a long distance Kitesurf for charity. Nothing too extreme. Thinking 100 - 150km would be doable? I have been kitesurfing for 3 years and am 34 years old. Is it best to go directly downwind or slightly cross wind. obviously I will have a rescue boat with me with different size kites incase of wind change. what are the other things I should plan for. which board would be best suited. Twin tip or surf. Was thinkin twin tip so I could ride toeside for a break? Any information at all would be great as I don't know much about long distance kiting and am trying to figure out what the possibilities are.
Yes indeed 150km will be hard but easily achievable. The world record for 24hr is 400+km
DONT go directly downwind! thats very difficult. go broach reach. cross wind with a slight down wind angle.
That will give you speed and line tension.
Study your gear for comfort. if something annoys you or chaffs in a short 2-3 hr session it will be murder on the 10 hour long distance fest. This will be what kills your attempt if you haven't sorted your set up.
EG a seat harness is most likely better suited to long distance than a waist harness.
Look for a hydration pack like a camelback an ways to store food so its easily reached without stopping.
In regards to the board, I would recommend a large twin tip board like a 150cm such as the Best Breeze. I would also ride cross wind, because directly downwind or close to it puts strain on your stomach and hips after awhile. Good luck.
