when windsurfing became a planing sport - ie more short board oriented - it became wind bound
now with SUP, WindSUP and KONA - some of the FUN and TOW aspects are coming back
about 75 % of my sessions in 2015 were on a longboard - Mistral Equipe or Fanatic Ultra CAT
people are afraid to use "large" sails - 85% of my sessions were with a sail in the 8.x range (8.0 - 8.5)
since it is about planing , there seems to be a wind minimum - usually around 15 knots
i go when winds are announced over 20 kph - that's about 11 knots
people here complain about gusty winds - they are ALWAYS gusty - get a sail with BIG range, adjustable outhaul, etc
in summary: the sport needs to go more about FUN, TOW , etc
long boards HELP in that area
here kiting is taking over ...
there are days when I go and the kites cannot !!
LONG BOARDS are the answer !!
