Scene slang for fast straight-line riding on the plane: long reaches back and forth, with no tricks and no waves involved. The freeride sweet spot for it sits at 15 to 22 knots.
Blasting is what most people picture when they hear the word windsurfing: planing, hooked into the harness, feet in the straps, pulling long reaches across flat water. The classic mistake is leaving the sweet spot behind. Chase every gust, rig smaller and smaller, and you burn exactly the energy you'll want in hour three — 15 to 22 knots is plenty for a long session. The second mistake hides in the setup: straps mounted far back and far out give control at 40 km/h and above, but on a relaxed blast they only cost comfort and manoeuvrability. Mount them centrally and moderately, stance slightly wider than hip width, then adjust in small steps. What often gets missed: blasting tempts you a long way out because it feels so easy. The rule still holds — never further from shore than you could swim back in an emergency.
