I find it incredible that this system was not widely used for all these years. I have seen versions of it for awhile, but not until the I20 did I really see it used on cats. Maybe others were using it, but that is the most prominant example that seemed to jumpstart it. I hope Bill's making a killing off of it, I know I sure love mine. I have sailed the Viper(20' monohull with open stern) and it has a molded in version, and I think the Laser 2 is doing something similar too.
Thanks Bill,
David Mosley
