2026 Ranger RT188P Garmin Livescope Cup Equipped

The 2026 Ranger RT188P is an 18-foot 10-inch aluminum fishing runabout built to handle shallow water and open water alike. It arrives powered by a 115-horsepower Mercury Pro-XS 4-stroke engine and comes equipped with Garmin Livescope technology for live sonar fishing capabilities.

The boat is designed for functional fishing layout with rod storage running the length of the hull — 7 feet of storage on the port side and 8 feet 6 inches in the center. A 24-gallon fuel capacity supports extended fishing days. The cockpit accommodates up to four people comfortably.

Dry weight sits at approximately 1,460 pounds, keeping the boat responsive and trailable. The aluminum construction and 0.100-inch hull thickness provide durability in varied water conditions. An included trailer with a gross vehicle weight rating of 2,950 pounds handles transport, with the boat and motor measuring roughly 23 feet 6 inches in total length once trailer-mounted.
