'I've got to admit, I was skeptical before I tested the Simmer SC11 masts, and for this reason, kept all my beloved custom Carbon Tech race masts (just in case).
After just 2 minutes on the water, I knew that the SC11 was a league above anything else I'd ever tested and hands-down better than all my custom ones. I was super impressed with the performance! As a huge plus the rotation is extremely good, coming from slightly more taper than most other masts. With constant curve, these masts crossover to lots of other brands. A few other local sailors have now tried rigging up their old sails on the SC11, and the upgrade was instantaneous.
Ohh, one other thing... the price is really damn good!
