The PRO518 is the largest of Saturn’s professional line, pairing military-grade 1.2mm PVC tubes with heat-welded seams. An aluminum floor and reinforced transom give it a rigid base for heavier outboards and loads. It is aimed at rescue, commercial and offshore work rather than casual weekend use.

Good to know
- An 18 ft inflatable with an aluminum floor is heavy, so plan on a trailer rather than carrying it by hand.
- Confirm the max motor rating with the retailer before buying an outboard to match.
