My 1985 Mac 22 has spent all its' life on the trailer when not being sailed. My boards seem to be sagging too much between the points where bolted to the trailer. I called Macgregor and talked to a fellow who's been there forever (when my boat was built). He said the boards are contoured to the boat at the factory and that I should not worry about the bow unless excessive 
and that I should be careful about using straight 2x6's.
Where the boards bolt to the trailer the hull is taking on a significant indent:cry:. Further investigation on the inside shows the fiberglass support between the hull and the inside shell is buckeling. I am going to remove boat from trailer (take the load off these four locations) and try to reduce the buckle while beefing up these support areas with more fiberglass.
I would like to replace by bunks with standard pressure treated boards from the Lowes. Maybe others have successfully use regular boards without any problems-- will the boards give enough so as to not put undue or unblanced support to the hull? Would be great to hear any experiences or advice. Thanks in advance!
