This is a proven, go-to, bottom design for surfboards that has stood the test of time for decades. It generates a lot of speed, yet enables the rider to make smooth, controlled, rail-to-rail transitions with minimal effort. This board features a tight bottom radius on the rails which contributes to stability and helps to get the board up and planning more efficiently. The Rusty is designed for intermediate to advanced wave riding. For larger surfers 220 lbs. and up. Great for surf touring from spot to spot. Of all the designs, this is ideal for beginners of all sizes and flat water paddling.
