The Grand Canyon Expedition’s “S-Rig” is awaiting your arrival…the pleasure in the job puts perfection in the work – Aristotle

August 12, 2015

Our S-Rig was specifically designed to navigate the rapids in Grand Canyon. Our rafts are constructed of industrial strength, nylon-coated neoprene that is extremely strong and puncture resistant. The S-Rig is a donut shape, 37 feet in length with 20 diaphragms to ensure only any one section could be affected by loss of air. A 22 foot side pontoon on each side of the donut stabilizes the raft in very big water.

Our rafts have been around for many years. Ron Smith’s vision of a boat for the Colorado River was designed in the early 1960’s, and is still the raft a majority of outfitters use. There are various frame designs as you will see on your Grand Canyon expedition. The design of our frames ensure a low center of gravity so that our guests can have a comfortable yet very safe ride and can be one with the river.

GCE rafts have been used around the globe, exploring the Omo River in Ethiopia, the Indus River in Pakistan, the Congo River is Zaire, and with Jacques Cousteau exploring the headwaters of the Amazon River in Brazil.   photo: 2015 GCE guest, John D
