The best thing for light wind is a wide flat TT. Mine is a 135x48cm custom TT I had Cardboards make to my specs.
It was based on a plywood board I made and rode for several years. The Cardboard is much lighter.
You could get quite a good result by just plonking some straps on a sheet of 10-12mm marine ply. (Strapless could be fun but a bit limiting.) The natural flex in the ply gives you all the rocker you need when it is loaded up.
A good light wind TT is liking adding an extre 2m onto your kite without the negatives that brings.
The wide board can get a bit skatey if your technique is off, particularly in chop and toeside carves. It does help focus your technique and when you get it right it is magic.




I had a magic session on Sunday. The only one riding for the first hour and having perfect, glassy small waves all to myself for most of the second hour. Bliss!!!
Finless is also good in light winds, although some small fins do make the board more forgiving.
As you probably know, avoid rocker in a light wind board.
Surfboards are bad because of too much rocker and too much fin drag.
Raceboards go faster upwind and at a higher angle but are too hard to ride in really light conditions.
A standard commercial lightwind TT can be almost as a good as a flat, wide TT. They are generally a bit long and flexy to be really good in light winds.
I have never tried a Door style TT. Lots of people say good things about them.
If I had to have only one board and kite it would be my light wind TT and a 10m bow kite.
