We have a 2015 R25SC and find that at 11 MPH the wake is at its largest. 11 MPH is wake surfing speed! Prior to our Ranger Tug we had always been slolom skiers behind a Sea Ray 240 Sundancer. Surfing that close to the boat is a different experience but once you get used to being that close, it is fun. Because the boat is going away from you, if and when you fall, it is safe, no different than doing it behind a ski boat. No fancy ballast tanks or wake plates needed with the Tug. As long as when you come back to pick up the downed surfer you do it with them on the Starboard side of the boat the visibility is just as good as most any other boat. Even on the port side if you do not approach too closely it is not a problem. Definitely need a competent watcher, but that is a requirement with any boat towing water sports.
