This allowed me to use my ART base in the tiga mast track. It made for a
very solid fit. The only downside was that I forfeited the sliding track
ability using the mast pedal. This wasn't a big deal for me since I
rarely changed position of the mast while sailing anyhow. I could still
adjust the mast base using the more traditional shortboard method of
taking the mast off, unscrewing the base one or two turns and sliding the
base to its new location, tightening it and plugging the mast back in.
Maybe this helps... it worked for me.
