I just screwed the standard tictac (plastic) backing plate to the deck under the foot of the mast. Didn't forget the sikkaflex. Hasn't moved.Have seen metal tictac bracket screwed in the same position, which neatly allowed the jib purchases to pass through, as well.All Tactic accessories available from the well known chandlers, I'm sure.
Yes, or direct from Tacktick. There are lots of mounting accessories available, including a permanent mounting onto mast track. See http://www.tacktick.com/page.contact - or they're at the Boat Show if you're quick.
