A few things to consider when choosing a Kiteboard!
Length and width:
The surface area of a kiteboard is achieved with a combination of length and width; an extra cm in width adds a lot more surface area than an extra cm in length.
Longer is not always better, a longer board will get you up and planning well, but is harder to maneuver.
A bigger board is also harder to hold an edge and drive upwind, and harder to hold the edge for boosting (but that is another chapter!)
Rounded/tapered tips reduce the surface area.
Squarer tips increase the surface area and allow for a wider placement of fins, allowing you to drive a board harder upwind.
A good all round board for light to moderate winds would be 134-136 x 42-43. This would be a way better size board than a 140-142 at only 40cm wide. The shorter wider board would be far more maneuverable and have more surface area than the longer narrower board
Rocker is the curve of the board from tip to tip. Rocker is important for getting through surf and chop. Flatter boards are good for flat water. (Fig 1 Rocker)
Multiconcave boards vs. Single concave boards:
Multiconcave can be a smoother riding board such as the Naish Monarch (Fig 2) and Drive (Fig 3). The deeper the concave the better the board will hold the edge, but harder to slide board around.
Other boards such as the new Naish Stomp (Fig 4) have 3D rails to give superior performance holding an edge and driving upwind.
Comfort guides you here, but more maneuverability is achieved with a wider stance with toes out. There should be room to move feet in straps to point both feet in direction that moving.
