We present the Patrik T4A FLOW 4WAVE HD sail.
The Flow 4Wave HD is the sail for riders who prioritize a light, agile feel over raw power. If you want to express your own style rather than struggle at the limit, this is the sail for you.
The soft Dacron luff panel delivers smooth power for early planing. The stable, forward-set draft makes the sail feel as light as a feather in your hands. The on/off response is precise, which makes it particularly strong in waves. Built on the proven 4Wave LTD platform, but even lighter, with better top-end control and a cleaner release in radical turns.
In waves, the sail sits lightly on your back foot. You focus on your riding style, not on the sail. Power is there when you want it. When you don’t want it, it’s gone. That’s exactly how it should be.
In the air, the Forward Drive gives you control over your airtime. You can quickly turn it off, making landings easier. This makes all the difference, especially in big surf.
An important point to consider when choosing a sail size: The Flow has an extended low end. That means you can ride one size smaller than usual. More agility, better wipeout resistance in big surf.
The sail performs from light onshore winds to epic down-the-line conditions. Kevlar protection in high-wear areas and an EVA-padded tack fairing ensure it still looks great even after many sessions.
