I've been reading for a long time on different ghetto gate options, and ballast configurations, etc because I've had the HARDEST time getting a surf wake set up on my boat. I own a 2008 22SSV with 750 lbs ballast center locker and 1100 lbs ballast in each ski locker. I've tried literally everything to surf behind this boat, and I have as of yet been unable to be able to drop the rope. There just hasnt been any push in the wave. It frustrates the hell out of me because I see all of these other surfers on the lake behind crap ass boats and they're surfing rope free, but they're 1-2' behind the boat and the wave has no lip or curl on it at all. I almost dropped 4k on the gosurfassist because I love surfing enough and I cant justify spending 100k on a newer boat when I can drop 4k on my boat that is paid for. Im glad I browsed around the internet and found this thing. All I can say is GAME CHANGER. The two videos are with the exact same ballast configuration and the exact same speed, with the wakeplate set at exactly the same setting. If you've been wanting to get surfing behind your boat like I have, the $500 I dropped on this thing is money well spent. The suction cups dont come off, the thing floats, and most importantly, IT WORKS.
First video is no delta device, second is with it.
