GS4 | CHS — Grey Shark Handcrafted

Balanced 4-Batten All-Conditions Performance

The do-everything wave sail. Four battens deliver the perfect balance of power, stability and manoeuvrability — from down-the-line surf to bump & jump to power carving. Built with Grey Shark material for riders who refuse to compromise.

One Sail. Every Condition. No Excuses.

The GS4 is the heart of the GS Collection — a four-batten wave sail that does everything remarkably well. Whether you’re charging down-the-line in clean swell, punching through choppy bump & jump conditions, or carving powerful turns in side-shore winds, the GS4 delivers consistent, balanced performance that adapts to whatever the ocean throws at you.

Handcrafted one-at-a-time in Senigallia, Italy, using Grey Shark material — an advanced Dyneema and ultralight taffeta composite with load-path-focused reinforcement. This means your sail maintains its designed profile longer, responds more precisely, and handles real-world abuse without losing its edge.

Why Riders Choose the GS4

The four-batten frame creates a smooth, predictable pull with outstanding draft stability. You get enough structure for confident power delivery, but enough freedom in the leech to keep the sail lively and manoeuvrable. It’s the rare wave sail that feels locked-in during gusts yet loose and playful when you want to throw a turn.

The GS4 carries the legacy of the legendary 4G — a sail shaped with input from Aloha Classic champion Alex Mussolini. That DNA lives on in every aspect: the perfectly tuned centre of effort, the instant acceleration, and the intuitive balance that makes complex manoeuvres feel natural.

What Makes It Different

  • Perfect balance — power and manoeuvrability in one tuned package
  • Stable draft — the 4-batten frame keeps the profile locked under pressure
  • Grey Shark construction — superior shape retention and long-term durability
  • Wide versatility — excels from wave riding to bump & jump to freewave
  • Smooth power delivery — no sudden pulls, no surprises

Who It’s For

The GS4 is the sail for riders who don’t want to choose between disciplines. If your sessions range from clean waves to messy chop, if you want one sail that handles everything with confidence, or if you’re looking for the best all-round wave sail you can buy — the GS4 is your answer. It’s often the most popular choice in any wave sail range, and for good reason.

Best for: All-round wave · Bump & jump · Versatile conditions Feel: Balanced · Stable · Powerful

Handcrafted. Customisable. Yours.

Every GS4 is individually crafted to order. Choose from a curated palette of premium colourways to create a sail that performs and looks exactly the way you want.
