Severne SDM APEX

FAQ

What makes the Severne SDM APEX mast stand out?

The Severne SDM APEX is a high-performance carbon mast with a Constant Curve bend curve and a carbon content of 90 percent. The Standard Diameter mast tapers by up to 15 percent in the middle section compared to the standard diameter, allowing for a thicker wall and thus a significantly longer service life.

Which sails is the Severne SDM APEX suitable for?

The APEX SDM was specially developed for SEVERNE freerace and slalom sails. It provides the appropriate bend curve and stiffness that modern race and freerace sails need for maximum performance.

What lengths and IMCS values does the APEX SDM offer?

The Severne SDM APEX is available in lengths of 400, 430, 460, 490, 530, and 550 cm. The corresponding IMCS values are 19, 21, 25, 29, 34, and 35, so that the right length is available for almost every sail size and application area.

How heavy is the Severne SDM APEX?

Depending on the length, the APEX SDM weighs between 1.60 kg (400 cm) and 2.40 kg (550 cm). The exact weights per length: 400 cm = 1.60 kg, 430 cm = 1.75 kg, 460 cm = 1.85 kg, 490 cm = 2.10 kg, 530 cm = 2.35 kg, 550 cm = 2.40 kg. The weight specifications have a tolerance of plus/minus 6 percent.

What is the advantage of the tapered SDM profile?

The medium taper of up to 15 percent compared to the standard diameter allows for increased wall thickness in the sensitive middle section. The result is a noticeably more robust mast that withstands the high loads of windsurfing and is more durable than classic SDM masts with the same diameter.

What does Constant Curve mean for a windsurf mast?

A Constant Curve bend curve ensures a uniform curvature over the entire mast length. This bending characteristic is ideal for modern freerace and slalom sails and harmonizes perfectly with the sail profiles developed by SEVERNE.

Why does Severne develop masts and sails together?

Designer Ben Severne precisely matches the mast and sail to each other. He first develops the mast and then designs the corresponding sail, so that the bend curve, stiffness, and profile form a perfect unit. This interplay is the basis for the high performance of a SEVERNE rig.

How do I properly care for my Severne SDM APEX?

The mast should be stored dry and protected from UV radiation, preferably in a suitable mast bag. Avoid impacts and excessive stress, especially in the tapered middle section, to maximize its service life.
