Mast SDM 460 Flextop, ideaal, North Silver 70% carbon

Mast 460 Flextop, dus geen "Constantflex, zoals Neil Pryde, maar North of Gaastra wel.

Mag ook North Gold 90 of 100% zijn, maar ideaal dus North SILVER 70%.

Bedankt!

Zou het kunnen dat Neilpryde toch flextop heeft? Sommige merken zijn veranderd maar Neilpryde is al heel lang flextop, dacht ik...?

aanvullend:

Neil Pryde was niet altijd FT, was toen zelfs 'officieel' CC maar...zeker n de langste maten was de praktijk ' CC met neiging naar FT'.

Zij noemen het ook geen FT maar Progressive Flex.

Over the years Neil Pryde has developed the “Progressive Flex” bend curve to truly
maximise sail performance, and in response to the demands of today’s sail designs,
which place large areas of material at the top of the sail to maximise the usable
area. Twist is one of the most important characteristics of sail design, and the
“Progressive Flex” bend curve allows the sail to twist as dynamically and efficiently
as possible.
Neil Pryde’s “Progressive Flex” bend curve maximises sail performance and twist
in 2 ways:
1. It combines a stiffer bottom section with a lightweight and responsive top section.
A stiffer bottom section is required for draft stability and power, while the lightweight
and responsive top section provides release in the head of sail for control.
2. The defined taper of the mast improves its responsiveness and dynamic
performance. It does this by helping to define the most accurate flex point
of the mast for any given wind strength, and by improving the speed of
transition between these different flex points.
Simply speaking, as the wind strength increases, a sail will twist and the
mast will bend from the top downwards. In light winds, only the top of the
sail will twist so that maximum power is available to the rider. In stronger
winds, the sail will twist even further to increase the level of control. The
better a mast can define the most appropriate flex point for a certain wind
speed, and the quicker a mast can transition between these different flex
points, the better a sail can react to changing wind strengths to give the
rider maximum power, control, stability and speed!!
