It’s always advisable to shop with professionals to find the right sea legs that will fit your boat.

Materials used in pontoon sea legs

The sea legs are usually made of aluminum is they are lightweight and resistant to water erosion. During construction, the aluminum is extruded onto the alloy tubing which is in turn installed at an angle providing support and strength to your heavy pontoon boat.

At the base of the sea legs, a footpad with dimensions of 48” x 18” is placed ensuring that your boat is solidly resting at the bottom of the river or lake. On the legs, four hydraulic cylinders are installed. 

Every leg is reinforced with steel alloy piston rods which have the capacity to hold up to 6500lbs which means that even heavy and bog boats can still use the sea legs.

Will the sea legs impact the performance of my boat?

The sea legs are going to add a bit of weight on your boat, but this is normal in order to provide the necessary strength and stability. The idea is to safely rest or tuck 6 feet on the lake/river bed or dock without any hitches when moving on water, the extra weight will hamper your movement.

One of the first things you’ll notice is the reducing speeds partly due to the additional weight of the pontoon sea legs. But, it’s vital to note that the pontoon boats were not designed for higher speeds, so the decreasing average speeds will not be much of an issue.

With regard to stability, there have been complaints of the whole boat tipping over. But this is not because of the design of the legs but rather lack of proper installation, if you are not keen during installation you might get stuck on a rock or muddy bottom which makes the whole boat and sea legs unstable.

How much does the pontoon seal legs cost?

Currently, on the market, there is a wide range of brands and they all have different pricing. But one thing you can count on is the sea legs are very pricy, the pricing of every unit is as follows:

As the size also increases, the price will rise. A three-tube pontoon will cost you $6,500 and an additional installation cost of $1,000. If you decide to go with the 26-foot lift canopy, expect to fork out around $4,500-$5,000 that is minus the installation cost, there is also an additional remote-control package for your sea legs and it will cost you $300-$400.

The good thing with the pontoon sea legs is they come with a warranty but the warranty varies anywhere between one to two years. Its always recommended asking your dealer about the specific details of the warranty as improper use of the sea legs can lead to the voiding of the warranty.

Note that the prices might not represent the true market value, do prior research to know what different brands cost, it might be a bit expensive but at least you’ll have a rough idea of how much they cost enabling you to plan before-hand.

I always advise my readers to buy the seal legs first before purchasing the pontoon boats as buying both at once can be a bit pricy.
