is in the details, eh?
Thanks JB. I seriously considered converting my mast this way when I swapped my 2007 for 2011 hull. Seemed it would not be that big a deal to put the female base on the older mast but I did not realize the height would vary that much.
Also, if the pinned base and the aluminum reinforcement collar are glued in place, this would be a very risky mod.
I actually tried to use the 2007 mast on a 2010 hull by removing the 2010's metal base plate, hoping the receiver holes would be the same. Did not work. it was too loose down there.
Steve - sad to say, if you want the option of newer TI style crossbars and mast cups, you'll need to pay for a new mast as well. ($900?). Adds up fast. And I think you'll like the hybrid, if you go that route like I did.
JB - are you referring to the height/alignment of the furling ring - or the mast collar?
BTW, does anyone have full shots of these two mast bases for comparison? (KBob, do you have both these models in your flotilla?)
