during the month of March, Annapolis Performance Sailing (APS) is offering their 10% off sale on their entire Harken hardware product line. additionally, if you spend over $100, you get a free gift (and naturally the gift gets better the more you spend!).
I use the Harken 2135 57mm carbo ratchet block for my mainsheet control on my Sunfish – it was a BIG upgrade over what I was using previously, and a HUGE improvement over the old hook that came standard on older Sunfish sailboats. I also use the H071 stand-up spring and the HSB2 spring cup.
with 10% off, now is a pretty good time to update your old gear or improve to a newer system.
