***For Serious Surfers***
You gotta be prepared to ride this board with your shoulders and hips as if engaging your rail on trim. Surf: Don’t Skate. Even for highly skilled skaters, helmets and pads are recommended. You know your skill level and you know your own limits.
We love your style but we also want you to take care of yourself. As the saying goes “Easy does it!” We don’t want you going all out on your first ride. Get to know your board and bond with it before RIPPING. When you’re ready, practice your blow tails and tail whips all day long, but skate within your limits and wear safety gear to keep you safe. The concave and swallow kick-tail allow you to get leverage on the deck for tail washes and 180s
Which HST Trucks should you get?
Hamboards produces trucks with four different pivot angles, 55°, 40°, 20° and 0°. After years of testing and customer feedback, we have identified three setups which cover the majority of skill levels and customer riding styles.
HST 40°/40° — "Dig and Carve"
Skill Level: Expert
This is the original setup that built Hamboards' reputation. If you're looking for deep carves and big turns with maximum versatility, this is the setup for you. The 40°/40° configuration delivers equal front and rear turning, letting you throw the tail of your board just like you're hitting the lip of a wave and carving back down the face. Once you're at speed, you have complete control over your ride—from easy cruising and technical footwork to wide-open shredding that digs deep into every turn. This is the ultimate performance setup for advanced riders who want the widest range of possibilities, whether you're seeking mellow flow or aggressive rail-to-rail carving that mirrors the most dynamic surf sessions.
HST 55°/20° — "Pump and Glide"
Skill Level: Intermediate
If you're looking for effortless pumping and that smooth glide-down-the-line feeling, this is the setup for you. The 55°/20° configuration creates the perfect balance of front drive and rear stability, making it ideal for practicing footwork and cross-stepping while maintaining deep rail control when you need it. Once you build speed, you can make that critical turn down the line and immediately transition into nose walking with more control and ease than ever before. You can still engage the rail and carve when the moment calls for it, but this setup prioritizes flow over power—perfect for riders who love the glide and want to focus on style, technique, and that meditative connection between board and rider.

Why the Twisted Fin is good for surf training

HST Trucks are different
Most skateboard trucks have flexible bushings which allow them to flex and rotate. Our patented HST Trucks use stiff springs and spherical wave cams that translate axle rotation into spring compression. These massive springs store the energy then give it right back to you. You don't need to lift the front to turn, just turn the board. HST trucks have smooth consistent rotations. The springs give strength and stability that enable the wheels to glide over road imperfections like you wouldn't believe.

Rotation and Lean
Our patented HST Trucks were designed to simulate a surfboard on water. Do not expect them to feel like other skateboard trucks. They are so responsive that some people call them loose.
Our trucks rotate up to 20° in both directions and lean up to 30°. This movement is much greater than most other skateboard trucks.
When you turn on HST Trucks, you feel like you are riding on an airplane wing in a banked turn. You get the sense that you are riding on the edge of your board, much like it feels to ride on a snowboard or a surfboard.
They also give just enough of a snappy return to center and truly feel like surfing.
