Pontoon vs. Tritoon Lift Sizing
Pontoon and tritoon boats differ in weight, width, and hull configuration, which affects lift sizing.
Pontoon boats typically require wider bunks and racks to evenly support dual tubes.
Tritoon boats are heavier and benefit from higher lift capacities and additional center support for the third tube.
Choosing a lift designed specifically for your boat’s configuration helps improve stability, protect the frame, and extend the life of both the boat and lift.

FAQs for Infinity Pontoon Lifts:
How is this different from a standard vertical boat lift?
It’s engineered with extra width, length, and supportive pontoon guides specifically to cradle and protect today’s heavier, wider pontoons.
Can I add a motor or canopy later?
Yes — our modular system makes it simple to add ShoreMaster motors, canopies, or guide-ons whenever you’re ready.
What water depths work best?
This system’s 66” rack travel and 84” high winch post handle fluctuating lake levels with ease. Your local dealer can measure your site to confirm the perfect fit.
Will this work for a tritoon?
Absolutely. The additional frame width and pontoon rail kits are designed to support today’s triple-tube designs.
What size pontoon lift do I need?
The size of pontoon lift you need depends on your boat’s length, weight, and configuration. Tritoon boats typically require higher lift capacities due to their added weight and center tube. Choosing a lift with adequate capacity and proper bunk spacing helps ensure stable support and long-term protection.
Are pontoon lifts hydraulic or manual?
Pontoon lifts can be hydraulic, electric, or manual, depending on the model and setup. Hydraulic and motorized options provide smooth, push-button operation, while manual systems offer a simpler, mechanical solution. The best option depends on boat size, usage frequency, and desired convenience.
