Ok so we have been noticing that when pulling on the downhaul, and sheeting rather tight up wind the mast gets some weird bends in it above the hounds. Almost looks s like in shape. Nigel had sailed olies boat 2 weeks ago and thought maybe the dimonad wire tension was off, or the spreaders not set right since the mast should bend more back not side to side (i believe that is what he was getting at since this is 2nd hand info). So now we are moving blade 1s spreader rake back and lengthing the spreader more. We are keeping mine the same and gonna try some comparasion next race. The question is will moving the spreaders like this change the prebend any, and will is cause the mast to bend more in the long axis then in the short axis. I am not an engineer so it confuses me. Thanks for the help
