A menos que tengas una vela de 2015 ó 2016, el mástil adecuado es un "Hard-top-constant curve".
Según su website, hablando de la nueva serie K de mástiles:
http://www.mauisails.com/masts.php
"To be clear about the changes in bend character, our Masts have traditionally had a “percent of midpoint deflection difference” between the ¼ and ¾ points of between 7% and 11%, depending on size, which according to conventional bend definition would be classified as “Hard-top-constant curve”. The new masts have a “percent of midpoint deflection difference” of between 10% and 12%, classifying them as “constant curve”. "
La tabla de curvas standard:

0-6 = Hard top
7-9 = Hard Top/Constant Curve
10-12 = Constant Curve

16-18 = Flex Top
19-21 = Flex Top/Super Flex Top
22+ = Super Flex Top
