Goya Windsurf Mast Seventy 70% Carbon SDM offers the fast response of carbon with the durable reserve of fiberglass. With 70% carbon, the mast responds instantly to pump movements and pressure changes, while the fiberglass component provides just that cushioning that makes long sessions in gusty winds comfortable. The SDM diameter keeps larger freeride and no-cam freerace sails in tight shape; the profile remains stable when it tightens, so you'll run course steady altitude without nervous feeling in the boom. The constant-curve flex fits seamlessly with modern Goya sails such as Mark and Nexus and works smoothly with many similar freeride cloths. A reinforced ferrule with precise fit prevents play at the seam, keeping batten rotation clean and allowing the leech to breathe in gusts in a controlled manner. The hard-wearing outer layer and included cover make rigging up, unrigging, transport and storage hassle-free.
On Dutch lakes, ponds and along the coast, you especially notice the balance between liveliness and calmness. In marginal winds, the fast reflex helps you plan ahead and stay going with less pumping; when it picks up, the mast maintains the shape and control you need to maintain speed over chop and shorter waves. The center section is torsionally stiff for instant acceleration out of jibe or tack, while the tip cooperates just enough to keep the pressure line neutral-pleasant for forearms and control on long races. Trim is straightforward: a quarter turn of extra downhaul tames coastal gusts, slightly looser gives more punch and acceleration on inland water. Choose a 430/460 for all-around freeride sizes or a 490 for larger cloths; in all cases, the Seventy remains light to handle, predictable in behavior and keeps its shape season after season.
