The average flagship wakeboard-specific boat (i.e. G23, X-Star, etc.), with a moderate professional weight plan (about 4,000 total ballast), can take roughly five to seven gallons of gas during an average wakeboard set. This means that if you're in a riding situation like this and bring just one five gallon can of gas, your host might be paying for the gas that you use in his boat. Not a great deal for him. With boats becoming bigger and heavier, the new norm for bringing gas for a pull now needs to be two cans for one set. If you're in a situation where you're riding with this person more than once a week and giving up ten gallons of gas every time you ride with them is too much, there is another solution. If you do ride with this person on a very regular basis, it's fine to alternate between bringing one can and two cans. This is only for someone that you ride with a couple times a week though. Similarly, if you go out to ride with somebody and are planning on taking two sets behind their boat, four cans may seem excessive. If this is the situation you find yourself in, it's alright to bring a can and a half for each set, meaning that you bring three cans in total. When taking two sets in one outing, it's better to keep them on the shorter side though.
