The 237 is a good boat. I have to say that with enough weight it can really put out a great wave. Unfortunately, I am not convinced it is in the same league as the best. I think it is close, but you need too much weight to get the desired effect. This might not be an issue for some, but for me once I ride the best wave on my boat I don't want anything less.
If I were to do things again with this boat, I would go with a bigger engine. I've got the 330 Black Scorpion and I've maxed it out. Even with the ACME 911 prop, I've reached the limitations of what that boat can do. I know it has more to give, but it just isn't possible as it is.
I think if you had this boat with a bigger engine, it could put out a pretty epic wave if you wanted to push it. The best wave I've made so far has been great, but I imagine Centurion or Tige boats put out a similar wave with less weight. So naturally I think their best wave will be better than what is possible in the Sanger.
But don't let that put you off. I love my boat. Of course there are things I wish were different with it, but I still have a hell of a time in it and behind it. I think everyone, if they're honest, could say this about their boats as well.
