The Alapai AI 285 9'4'' x 28'' x 4'' is a versatile paddleboard based on a single-layer Drop-stitch construction, which makes it very strong and stable. Drop-stitch construction is made of thousands of thin threads connecting the inner part which is capable of maintaininig the shape even at high pressure. This is needed when inflating. The tread of the float is covered with a non-slip soft EVA layer. The bungee cord on the frotn lets you attach a small load.
