It’s going to be an interesting time with the Olympics in 2016 hopefully the major manufactures will make a cheap introductory board and not go the way the windsurfing industry went
If weight was not an issue with race boards the split board has 3 parts so if you did get water in it the water can only go in one section and not soak into all the board
Funny thing is I have made kite speed boards for years and we put 2kg weights on the front end to keep the board down in choppy water and improve control at speed
Hypothetically if you had a mast foot box on a kite race board you could try it out and see if it would help in chop? And stronger winds
Multi hulled boards could be next, have never seen one yet but Why?: - less wetted area at high speed and sideways grip? = smaller fins more control?
The kite / windsurfing industries need to have more innovative people like the web site with the internet we only have to post an idea and someone may be able to help there are a lot of people out there who have fantastic ideas and should be encouraged
