Sailing ten yrs, GPS style, nearly done 25000kms on gps, did have basic understanding as sailed/windsurfed as a kid, about a twenty yr break from taking it up again
I went, jp excite, too much initially
So I went jp fun ride, sweet, took me from non plaining, to plaining, straps, basic airs and turns about 6mths
went to supersport, sweet, took me from about 20kts to 30kts, board speed style plaining gypes, airs, about 1yr
then went to slalom boards, I've had about twenty different ones, different brands, about...forever
I recommend developing some good sailing skills, a variety of conditions, plaining, straps, tacks, and basic plaining gypes before going to a dedicated slalom boards,
the first couple of yrs into windsurfing is awesome, from first plaining, to airs to your first plaing gypes, its a great time, and really rewarding
theres no need to do this at real fast speed yet, slow it down, and develop some skills and experience in a variety of conditions
you can develop great free riding skills on a slower board, then eventually move towards slalom, more speed, flatter water
In my opinion, the negative of the GPS, is too many are just rushing onto flat banks, bearing off, and some are not developing very much skill
theres guys that can go 40 that cant tack or gype, I would recommend enjoying the development of all the skills that make a great sailor
If your aiming to be a great freerider, then slow it down, over the yrs, with the combination of your forged skills and experience, add the potential for more speed
Good luck Mark, I loved the first couple of yrs, at that stage it was just pure fun, with no performance aspirations, enjoy
starting out, you don't need heaps of boards, but as you get better, and try to perform better in avariety of conditions, then that's the need for more boards in an attempt to fine tune the conditions
I would think two basic sails, and one beginner freeride board would cover you from zero to thirty knots for a while, a couple of fins, that's a basic recreational approach
If it develops from past time to lifestyle, then you will get more gear on your way to the top, good luck
