Wait a minute ... You may need to keep it in good shape so you can bring it on board Vee Jay for NA2013 in Barrington ... I hope it is not a "heavy" weight main. We will slide the tidesmarine track out. and by that time i will have the base of the mast moved to 25mm. I am not planning on gettin a new OD main ... when I use heavy tides marine slides on my normal programs.
