A windsurfing shop is a place that can sell you anything from a brand new rig to the bits and pieces that make maintaining your existing gear possible. The shops are by and large run by people who love windsurfing, so that they can share the sport they love with others. This makes them great places to go to get not only supplies, but advice.
So if you are looking for a sweet spot that isn’t too crowded, hit up the local windsurfing shop for advice. Some shops can even set you up with lessons to get you started if you’re a first timer. These are the little things that a good shop will do that lets you know it is staffed by people who care. However they aren’t the bread and butter of a shop.
That distinction goes to selling parts and supplies. A windsurfing shop will sell a lot more fins and cord than it will sell boards and masts. Adjusting your fins to wind and wave conditions is one of the best things a boarder can do to ensure they have a good balance of control and mobility. If you’re in light wind conditions and flat water, having a tiny sail and huge fins will only ensure you are dead in the water, while that same setup will ensure you don’t fly away in heavy wind conditions.
