Thanks a lot for the discussion. I have spoken with Harken and am going to do the mod. The track will accomodate a bend of about 4 inches over the length of the TheMightyHobie18 crossbeam so there should be no problem. If it is more than that they can ship a pre-bent track. The stock item on my boat has suffered from a previous owners neglect and is oxidized and scarred. I don't want to spend the man hours fixing what I view as a technologically inferior design. Of course this was designed at least 25 years ago.......

Cheers.........Nelson
