RE: I beg to differ.
You should also consider using the boards that you already have longer. Sailing experience is the key, here. I've gone through a number of boards in my windsurfing years and currently own five. One board I bought more than a year ago, but haven't found the opportunity to use it. Not that I don't put in my TOW as I had 45 days out last season. It's just that if you live in one location, your sailing conditions don't change all that much from my experience. I didn't find the winds to warrant using that board. I also find I can't take all 5 boards to the beach every time. Not only that, I'm still looking to pick up another board. You have to control your aggressive tendencies or they will work against you!!!
