Pontoon boats are the kind of boats that started off with operating on slow platforms.
You can actually take a pontoon boat into seawater, but there are certain conditions that you have to keep in mind before doing that, such as wave size and corrosion.
Size of waves
What is the size of the waves on the platform of your pontoon boating? If the waves will be either equal to or below 2 feet, then your pontoon is going to stay stable, even in activities such as trolling and anchoring.
However, if the waves are above 2 feet, the chances of them hitting the boat increase. The waves will crash into the boat, making them vulnerable. And as we know, salt water is heavier than freshwater so it will cause more damage to the surface of the boat than freshwater.
Bottom line: you can use your pontoon in saltwater if the conditions are under control, for example, in places like mangrove swamp, or a saltwater bay that is protected. The trick is to keep your eye out for approaching weather conditions and avoid any rough conditions.
If you are out on the ocean, you will be more exposed to the sun, and for a longer period of time. However, when you are on a lake, you have more chances of finding shade. While on a lake, you can ease up to a shady area or stop for lunch. But when you are on saltwater, you will not be able to do that.
So make sure that you don’t make longer plans when you are taking your pontoon boat out in the ocean. You will be exposing your pontoon to more damage that way. This way, your pontoon will be receiving damage from both saltwater and the waves. You need to minimize both kinds of risks.
Corrosion due to saltwater
One of the biggest problems that aluminum boats have to face while out on the saltwater is corrosion. Aluminum itself is fairly non-corrosive. But different metal fittings are attached to it, and saltwater serves as the perfect conductor and causes galvanic corrosion.
This contact between aluminum and metal fittings is isolated by boat makers in many cases. However, you still need to take certain steps before you take your pontoon out on the saltwater, to prevent corrosion.
After you come back home from a day of boating in the saltwater, you should wash your boat thoroughly. Make sure you use a high power hose so that it flushes out all the saltwater. Doing this will remove the saltwater that is trapped in the bumps on the surface of the boat. It is recommended that you don’t store your pontoon in saltwater. However, if there is a need to do that, make sure you paint it with anti-corrosive paint.
