The 873 has tons of lift. The high effciency and its large outline will permit you to surf knee high waves or pump in flat water.
The same DNA as the 633, its adopts the inverted gull wing shape and concave bottom. The large wingtips will squeeze the water while pumping and give you that extra drive to generate speed through your carves.
Ideal for small waves and using a windwing in light to medium wind.
