There has never been an occasion where we have needed to reef, and frankly in the 20+ years I have been racing these things I have never seen a tuna reefed, nor have I seen a modern main sail with reef points. (basically just dump the trav or main sheet if you are over powered) We have raced all over the country and in 20+ regularly(though intermittantly out here;) ). There is really no need. If you absolutely had to, a bullet block on the base of the mast where everything else is, a small cheek block on the front of the boom and a line through the (now defunct but some boats had them)topping lift block on the end of the boom should suffice. No need to get the $$$$$ system as any reef you put in will make the loads extremly small......... Might I suggest a Jib instead??
