Hi all, new member to the forums but have been using Seabreeze for wind reports for a a year or more now.
My wife and I have decided we like the idea of SUPing, we both kayak and I surf a 9'5" mal. We started looking around at equipment and saw that the cost for a new board is $$$$. We borrowed a standard windsurfer board off a friend and use one of our kayak paddles.
We can both stand and balance no problems and after about the third session and after watching some instructional video's on various websites can get along at a decent pace.

We will be using it on flat water (lake) at least once a week and in the surf maybe 3-5 times per year. We would also like to be able to sit our young kids on the board with us on the lake.
What size boards should we be looking at and what will they paddle/handle/balance like compared to the old windsurfer board we have been using. I'm 6'5 95kg and my wife is 5'8" 55kg and both athletic.
Thanks!
