A third tube definitely improves the performance of a pontoon boat. This option permits the installation of a hydraulic steering system and the tube performance kit. Let’s look at these performance details more closely

Better performance

Because a pontoon equipped with the third tube floats higher, it glides above the waves instead of crossing them, eliminating friction. This also allows to increase swiftness while not requiring more horsepower than that of a pontoon boat equipped with 2 tubes.

Fuel economy

Not only does the third tube improve performance, but better fuel economy is also achieved since less friction equals less work for the engine. In addition, the underside of the three-tube pontoon boat is entirely covered with aluminium, thus hiding the crossmembers. This eliminates another significant source of friction, further promoting fuel economy.

Better manoeuvrability

A three-tube pontoon, equipped with the hydraulic steering system, is much easier to manoeuvre when turning and docking. Furthermore, our extensive testing has proved that the centre tube of greater diameter than the lateral tubes – exclusive to Southland – significantly improves performance by allowing for tighter turns.

Better stability

The optional 34-gallon fuel tank built into the central 3rd tube increases the balance and cruising range of the pontoon. This eliminates the need for the tank under the sundeck, making room for even more storage.

Smoother ride

A third tube improves pontoon stability. Since the third tube increases contact with water at the center of the craft, the waves’ pitch and surge effect is practically eliminated.

More capacity

A pontoon boat equipped with three toons greatly increases the load and power capacities
