We answer a lot of questions pertaining to the subject of “how to weight a v-drive boat for wakesurfing”. Instead of diving into the details about filling and draining I am going to keep this simple. The end goal is to surf without the rope. This can be accomplished with a minimal wakesurf ballast bag upgrade. By adding more weight beyond the factory ballast system the surf wake will be bigger faster and the push will be stronger. Friends don’t let friends surf two inches from the swim platform.
Step 1 (Good): The first step to weighting any inboard boat for wakesurfing is to load down the rear corner on the surf side. Displacement of the stern deeper in the water will direct the flow of water while also promoting list or leaning. The result is a ridable wave with a cleaner face. Just this step will allow most riders to surf without holding onto the rope with the appropriate wakesurf board. Larger riders may need to jump to Step 2 in order to maintain the speed needed to throw the rope in the boat.
Step 2 (Better): Our preferred next upgrade is to add some weight forward in the boat toward the bow. We want to displace more of the boat’s hull deeper in the water. This will decrease the height of the wave but in turn will create a longer more ridable area further behind the swim deck. This upgrade is a balancing act so use the bow weight sparingly. Too much and the wave will flatten out leaving you with no speed. Not enough bow weight and you will be surfing with the nose of your board over the swim deck.
Step 3 (Best): To maintain the height of the wave while increasing the push or ridable portion of the wave, begin to add more weight to the mid ship on the surf side. If you want the ballast hidden toss a ballast bag under the seats but if you don’t have a lot of passengers throw a bag right on top. The amount of weight should be around 3/4″ of the total weight in the rear compartment. The name of the game is weight distribution. It should taper from the heaviest bag in the rear corner to the lightest bag in the bow.
Testing: When discovering what works best in your boat remember that people count too. If you want to experiment without having to spend the money upfront, invite your largest friends out for a day on the boat. Never ask how much they weigh as they might not be your ballast buddies after you surf. Guestimate how much weight is placed in these three key areas and then replicate that based on storage dimensions and the appropriate sac sizes.
