After running the wilderness section of the Chetco River last June I was inspired to design a new SOTAR inflatable kayak that could carry overnight gear. I also wanted a boat that would act more like a small raft rather than a traditional inflatable kayak. My friend Billy Miller paddled an Alpaca on our trip and I noticed some advantages to the larger and non-diminishing tubes.
My first design goal was to make the boat as maneuverable as possible, so this inflatable kayak is shorter and wider much like modern hardshell kayaks. It has a blunt end that will make it better for running large drops and more predictable while running big holes.
The second design goal was to design a boat that could easily carry several days of overnight gear. This was accomplished by choosing larger 12" tubes for flotation and stability while loaded. The blunt ends also allow more interior space and therefore more volume for gear. The tubes are full size all the way around the boat, so gear can be packed in the ends of the boat and remain stable.
We chose PVC for the material to make it less expensive, lighter, and easier to repair. To further reduce weight (and expense), there is only one air chamber for the outside tubes. This is not allowed on some permitted rivers, so SOTAR can make this boat with an extra valve and baffles upon request.
There are a few other advantages of this design. Since this kayak is designed like a raft, the fabric is cut in smaller pieces. It's much more efficient to cut from the raw material, one of the biggest expenses in boat design. This boat is also designed to pack small for flying on airplanes or hiking into remote places. There are small d-rings inside the boat made for tying down dry bags and other gear. We're also adding bomber handles to the bow and stern that will make it easier to portage, even with a full load of gear.

Kalmiopsised [Cal-mee-opp-sis-ed] -adj. 1. being cold, wet, exhausted, and happy in Oregon's Kalmiopsis Wilderness. 2. in pain and despair in a rugged, harsh place with a big smile your brain is trying to relay to your face muscles. What is the Kalmiopsis? First of all, it is a tongue twister of a word to pronounce. But more importantly, it is the name of a 180,095 acre wilderness area in southwestern Oregon. “The area is characterized by deep, rough canyons, sharp rock ridges and clear, rushing mountain...
It is truly an honor to outfit trips on the Chetco River through the Kalmiopsis Wilderness. This extraordinary trip begins with a 10 mile hike (with a heavy pack) to the river followed by 20 miles of paddling Class III and IV rapids (and some portages) in an inflatable kayak. It's a challenging journey but you are rewarded with absolute solitude and beauty. Last week a few hardy souls joined us to make this epic journey at a flow of 500 cfs. The Hike First of...
