Hi, I’m Tom and I’ve been boating my entire life. I specialise in RIBs. So, today’s question is what size engine do I need to water ski or wakeboard behind my RIB. Well, it’s not a straightforward answer because it can depend on so many things. The length of the RIB, the weight, the shape of the hull, how many people you’re putting on board. So, I can give you a rough rule of thumb, but you’ll need to think about those things.
For a five-metre RIB, you’re probably going to need at least 60 horsepower. As the RIB gets bigger and heavier you’re gonna need more horsepower. For a six-metre, you’re gonna need about a 100, a six and a half probably 150 horsepower and so on. If you want some advice on what size engine for any particular type of RIB then it’s best to speak to an expert, so you can make sure that you can be able to pull that skier or wakeboarder up behind the boat nice and comfortably.
