⚡ THE POWER BEHIND EVERY GAASTRA SAIL ⚡
A great sail needs the right engine. 💨
Gaastra Masts are designed to optimise your sail profile, stability and response on the water — combining lightness, strength and performance thanks to high-quality carbon construction.
🏄♂️ RDM or SDM?
🌊 Wave, Freestyle & Comfort → RDM
🏁 Freeride, Slalom & Racing → SDM
And then comes the carbon choice:
🔹 50% / 70% Carbon → durability & great value
🔹 80% Carbon → lighter, livelier & more efficient. HM Carbon construction
🔹 100% Carbon → maximum response, acceleration & lightness. HM Carbon construction
With their constant curve, Gaastra Masts are perfectly matched to Gaastra sails and compatible with most sails on the market.
It’s not just about weight — rig balance is what really matters.
That’s why, in some cases, a freeride sail can actually perform better with a 70% or 80% carbon mast than with a 100% mast.
The right mast is not always the lightest one. It’s the one that gives your sail the best balance, response and overall feel on the water. 💨
👉 What’s your choice: RDM or SDM? 50%, 70%, 80% or 100% Carbon?
