Just by reading the title, you probably have a good idea of what this post is all about. We wanted to clarify, however, that when we say “your modern Supra or Moomba,” we are specifically referring to models recent enough to have integrated surf systems. If you own or are thinking about owning a 2014 or newer Supra or Moomba, this one is for you! With that said, most of what we’ll discuss below actually applies to V-Drive boats in general, and not just these two brands. Now that we’ve taken care of that, let’s jump in.
This may seem obvious, but when you break it down to its simplest form, creating a powerful wake behind a boat is all about displacing water. The more water you displace, the bigger and more powerful the wake is. For example, a 400,000 ton oil tanker creates a much bigger wake than any water sports towboat in the industry could dream of. That’s a pretty extreme example, but the same concept applies to boats in V-drive category. If you’ve tried out some of the methods above and still don’t have quite what you’re looking for, odds are you may want to invest in some additional ballast.
While your boat is outfitted with plenty of ballast and wave-creating technology right from the factory, it is human nature to continuously strive to make things bigger and better. So for those of you that won’t settle for less than a tsunami, here are a few things you may want to consider.
No matter which late-model Supra or Moomba you own, your boat comes with ballast bags from the factory that fill with water using integrated pumps. There are many configurations, as some boats have just bags, others have hard tanks that flow into soft bags, and many recent models have bags that are completely hidden underneath the floor. Regardless, larger or additional ballast bags can help you achieve much more displacement and help maximize the wave your boat creates. In most models you may simply be able to purchase larger bags to replace ones from the factory, and in others you might consider additional bags with an external pump. Whatever you choose, ballast bags offer you the advantage of being able to create a great wave when full but being virtually weightless when empty. If you’ve got questions about what type of ballast bags would help you create a better wave in your specific boat model, give us a call or let us know here.
Another popular form of ballast are lead bags. Contrary to their commonly used name, these small, 50lb bags are actually typically filled with steel pellets and provide a great alternative to typical wet ballast bags. Their biggest advantage is that they are very compact, can be moved around easily, and don’t require any time to fill. However, the advantages of lead bags can have some drawbacks too. Because their weight is constant, they can have an effect on fuel consumption when just cruising around the lake. With that said, many of our customers find that the combination of their factory ballast system and a few hundred pounds of lead bags helps create their ideal surf wave while not becoming too detrimental to their fuel consumption.
