The outline resembles a single fin in the nose due to the fact the original custom Yo was a 1finbox + 2 trailer setup. The tail however pulls into a rounded pin tail which will give you plenty of hold in the bigger stuff, and provide a lot of curve around the back foot. The extra volume in front of the chest gives you speed down the line and the rounded pintail to draw tighter arcs in the pocket. The Yo is just as comfortable as a thruster as it is a Quad making it the ultimate travelling board, Quad for the fast days and thruster for the big arcs. Go Yo Go
