Вот такое было описание к черной:
The V10L is a lower volume version of our award-winning V10 surf ski. We've lowered the front deck to decrease windage and moved the seat up 2" to give a better position for smaller to mid-sized paddlers. The V10L is proving very popular in areas that don't regularly encounter 6'+ waves. A heavier paddler and/or someone regularly paddling in areas with waves over 6' (2 meters) high would be better served by our V10 model. The V10L has an adjustable footbrace with self-adjusting pedals designed to fit shorter leg lengths — accommodating paddlers from 4'11" to 6'3" tall.
А вот здесь, я так понял, более подробное описание, тоже на английском: http://www.epickayaks.com/news/news/dev ... 12-surfski
