PRODUCT INFORMATION

Expedition-Ready and Surprisingly Nimble

The 18’ SOTAR Liquid SL is the largest raft in the SL series, built for extended adventures and large-volume rivers. But don’t be fooled by its size — this raft is designed to maneuver like a smaller boat, giving you the best of both worlds. Whether you're leading an expedition or just packing extra comforts, this raft handles it all with ease.

Massive Interior, Superior Stability

Featuring 26” to 21” diminishing tubes that taper at the interior and base, the 18’ Liquid SL maximizes space without sacrificing performance. It has a cavernous interior for hauling gear, passengers, or outfitting setups, while maintaining enough responsiveness to dodge obstacles and handle technical runs.

The Ultimate Raft for Multi-Day Explorers

If you're planning long trips on demanding rivers, this inflatable whitewater raft is built to go the distance. The SOTAR 18’ Liquid SL blends expedition-ready volume with reliable handling and comfort, making it a top-tier rafting boat for rivers that demand endurance and capacity.
