Sail in a private house on the seafront on the Costa Brava. This sail had to be very robust (we all know the strength of the Tramuntana) and be able to adapt to the different hours of sunshine. Challenge achieved! We made an EXCLUSIV sail (with a perimeter hem to incorporate the dyneema line), a metal plate was incorporated in each fist (corner) of the sail and a guide was added to the post to be able to easily raise and lower the anchor point.
