Hot Sails Maui - Windsurf sail

New for 2019 we introduce the Monster RDM mast. With a carbon content of approximately 65% to significantly reduce the price while still delivering great performance. More glass is used in place of the carbon which results in great impact durability with only a small weight penalty. The Monster is available in sizes from 340 to 430cm and is a suitable mast for wave and crossover sails. If not extended, the performance is nearly as high as the Kauli for lighter sailors. In comparison it is slightly softer, a little heavier, but the difference is subtle until pushed into extreme power wind where the softer mast will feel less responsive. This mast should not be extended beyond 30cm.

Manufactured using pre-preg composite fiber in a 'roll-wrapping' process to produce masts of the highest possible standard. The unique pressure wrapping system, developed after years of exhaustive R&D ensures hi-tech composite tubing of the ultimate in strength and stiffness-to-weight ratios.

Each mast is supplied with a durable padded mast bag with all plastic corrosion free zipper for convenient storage.
