some personal tips on uphauling on moderate to high wind speed. intermediate or advance players can jolly water start themselves.
1) adjust yourself, board and sail to the best position to uphaul.
2) back facing wind, board perpendicular, sail facing you = this is the best position to raise up the sail.
3) lock your legs, back, shoulder and arms to fully utilise body weight to uphaul.
4) it's a balance of yourself, the rig, the wind and choppy waters that needs to get the hang of.
this is probably be the hardest hurdle to cross before anyone would start enjoy windsurfing, which many gave up.
