We have stock of the Smik V4 Wingfoil Board in the most popular sizes for beginner foilers.
The 6'6 135L & the 6'9 150L.
 
Simon recommends learning on a board that is between 30L and 50L above your weight. 
For example, for a body weight of 100Kg, select a board of between 130L and 150L.
Skill level, age and previous water sports experience all contribute to whether you should be on a board 30L above your weight, or 50L above your weight.
 
If unsure, the larger board is better because it's much easier to be learning on a bit too large board than a bit too small board. And you will have to sell your first learner board to upgrade to a smaller board once you progress, so it makes sense to get the right size board to learn on, rather than try to learn on a smaller board with the idea that you won't need to change boards later as you progress. 
 
About the new V4 Wingboard:
Narrower and thicker than pervious incarnations make for a more agile feel in turning.
Longer flat and higher volume tail make for easy popping up onto the foil.
Bevelled rails make for smooth touchdowns. 
Aerodynamic nose makes it pierce the air efficiently. 
PVC wrap carbon decks make for super  light and tough.
