Here's one (bit like the sci-fi thread since im not very original)
What will windsurfing be like in FIFTY yrs time?
I believe that they will have invented: SEVEN piece masts. Boards with Cup holders. A device that stops the nose of your board getting whammied (one that works). Reasonably priced fins. Booms with internet access and mp3 player. European styling. windsurfing friendly wives/girlfriends
By 2057 windsurfing will have finally died out after all the stick in the muds have gone and the greater consciousness has realised the superiority of kiteboarding
Freeride boards will be that fast we will be able to sail to maui and back in an afternoon, so jumps at this speed will be in the 100's of meters not 10's, but the rig will be that good you will be in complete control all the time, triple no handed fowards will be an entry level trick. there will be people sailing in the middle of the ocean not just near the beaches doing massive jumps off the ocean swells in 50knots. half the sailors on the water will be girls and by law have to where bikini's. and there will be still guys on "92" model gear saying is the best thing they have ever sailed.
