The "goodness" of the Kayaksailor rig is, like most things related to kayaks and sailing, specific to the task at hand. I have used the sail on two, separate weeklong kayak-camping trips in my Klepper Quattro in the Florida Keys. I have also logged countless hours with the rig on my Feathercraft BK on the intracoastal in S. Florida. It has performed well in "big" wind and seas and in gentle puffs. As for being complicated, it is anything but, and that is what makes me a fan. The sail deploys or stows without drama using a pair of control sheets. It takes literally 2 seconds to deploy or stow, and, once secure on deck, it is nearly invisible to the wind.
In very heavy wind, and I call that +20 knots, the sail has the uncanny ability to dump power and maintain control via a twisting sail head. Not sure I really understand it, but it works. I am not saying you could not capsize in a single with the Kayaksailor, but I don't think I could put the Klepper over if I tried.
In a big wind I can maintain a comfortable 6 mph on a reach and on a run I have kept up an 8mph speed (I know, some want to keep this in knots, but I have my GPS set to mph).
If I was on an Alaskan expedition, would I want outriggers? You bet. But for everything else I do I prefer the simplicity and efficiency of this rig.
I have not yet tried the Balogh rig, but I probably will in the near future...now that the company is under adult supervision
But, until I actually try it, I would not presume to offer an opinion about its functionality.
If anyone is in the Atlanta or Palm Beach area and wants to take a look at the rig I would be happy to oblige.
