For what it's worth......
I have an older Islandia ('05). We found towing from the loop put people thru the rooster tail too much, unless we used quite a long tow-line. Also, the wakeboarders wanted 'big air'.
We put on an aftermarket tower (MonsterTower). For the amount of towing/tubing,boarding we do, it was great. This has made an already versatile boat even better.
Enjoy the boat.............JB
