I have an '89 Malibu Skier. I have been thinking about buying a surf board, probably a green room or landlock. Will I be able to surf with any success behind this boat or should I save my money? How much weight would I need and where to make it possible? Any other suggestions for boards that are good with smaller wakes?

You can probably do it. My boat is similar in size to yours and I can ride the Skimskate and Landlock behind my boat. The skimskate is definatly harder to find the pocket than the land lock. So I'd reccomend a larger board for learning. I run 550 in the bow and 700 on the side we're surfing. The wake is a little small but it's certainly doable.
