Dick Van Straalen 5’8 Hydro Hull PU
Hydro Hull is one of Dick Van Straalen’s signature fish models, characterized by deeply concave decks and bottoms. The concave deck ensures stability during paddling and riding, while the bottom concave transitions smoothly from convex to a triple plane single, delivering exceptional lift even in small waves or choppy conditions. This allows for faster takeoffs compared to other boards, even as the board grows in size. The board maintains excellent control across a wide range of wave conditions, offering a comfortable high-speed surfing experience.
This PU+onfin version, produced in the later years of the shape’s development, features a looser, more flexible nature than the standard EPS version, making it a rare and valuable board.

I’ve surfed this board in both small and medium waves and it handles well. The concave design gives great stability when paddling and the takeoff is noticeably faster than other models I’ve tried. The flexibility of the PU material makes it feel more forgiving on chop. It’s a solid choice for experienced surfers looking for performance in variable conditions.

This board performs exceptionally well in choppy water. The transition from deck to bottom is smooth and the lift is consistent. I appreciate the control even at higher speeds. The only downside is it’s not as forgiving for beginners, but for someone with experience, it’s a great tool.
