The description of the PFI is the opposite of my experience. I foil at 10mph and the PFI 633 fails to work at less than 12mph. Meaning that it's range of speed is limited. The Gamma 68, which is smaller works just fine at 10mph. When your boat has a small wake and you want to ride without the rope it's important to get these details correct.

What does PFI, PFH, and PTM actually stand for?

Thank you for this.

Will a Phantasm front wing work on a Hover Glide fuselage?
