The Leisure Pontoons 1723 Island 2006 vs Leisure Pontoons 2023 Navigator 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Leisure Pontoons 1723 Island 2006 at 17,0 ft versus Leisure Pontoons 2023 Navigator 2006 at 19,0 ft.

The Leisure Pontoons 1723 Island 2006 comes in at 18 lbs per hp versus 738 lbs per hp for the Leisure Pontoons 2023 Navigator 2006. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Both are inflatable designs, which means they pack down for compact storage, can be carried in a bag, and are dramatically lighter than equivalent rigid hulls. The trade-off is setup time and the need to monitor tube pressure regularly.
