Retrospec Coaster Inflatable Kayak – Tandem Review

Retrospec Coaster Inflatable Kayak Tandem


Inflatable kayaks are gaining in popularity for the same reason as inflatable paddleboards. They’re affordable, far easier than conventional kayaks to transport and store, and steadily increasing in quality and performance.

Does Retrospec’s 12’ 6” long, 39” wide Coaster kayak measure up? Here’s our take on everything from assembly to construction…and performance on the water.

Blow Up

Retrospec Coaster Inflatable Kayak Valve


While it may look daunting at first, going from backpack to fully inflated kayak on the water is pretty quick and simple.

Like many inflatable kayaks in its price range, the Coaster uses a PVC air bladder/external polyester cover combo similar to the inflatable tow toys pulled behind boats. Sides and floor are actually three separate bladders, already positioned within the stitched, 600-denier polyester cover. The latter adds shape, colors and graphics but most importantly protects the internal bladders from abrasion. For added durability, the lower half of the hull swaps out the polyester fabric for a heavy-duty PVC. Inflate to the recommended 1.5 PSI via the included dual-action manual pump, or fill with an electric inflator before topping off with the manual pump. Both are comparatively quick given the low pressure required. Two-part, threaded “Boston valves” allows for easy inflation and deflation. Make sure the valve is screwed in snugly at the base, and inflate via the smaller threaded top cover; deflate by unscrewing the entire valve. When doing the latter, just don’t lose the valves as they’re not tethered.

Though the Coaster’s bladders were well placed within their cover, this style construction can end up misshapen and often under-inflated. Tip? Partially inflate each of the three bladders until the kayak takes shape and adjust if necessary, before bringing individual tubes to full inflation. Ideally the cover should be firm with no significant looseness or puckers, but avoid going overly tight. Unlike some higher-end models, there’s no pressure relief system. Going beyond the recommended inflation pressure risks popping the bladders or tearing a cover seam.

Some Assembly Required

Retrospec Coaster Inflatable Kayak Seats


Minimal assembly follows, and depends in part whether you want to use the Coaster tandem or solo. Two inflatable seats are included, likewise using Boston valves. (They’re smaller, but don’t worry, the pump hose has both fittings.) Position seats almost anywhere along the kayak’s length via parallel Velcro strips. Padded backrests adjust via nylon web straps hooked on each side of the boat. Dense foam footrests covered in polyester fabric can likewise be fastened via those same Velcro strips according to paddler’s height or leg length.

A pair of three-piece aluminum paddles assemble with ease, but lack adjustability. We found them a little short for our liking, causing us to lean a little more side to side for maximum effectiveness. Kudos, however, to their asymmetrical, dihedral blade shapes. They allow the blade surface to be more even when it meets the water and water to flow more smoothly over the blade halves. Blades can also be angled to one of three settings.

Last but not least, tip the kayak on its side and add a trio of fins. They slide into iSUP-style fin boxes and secure via tethered, plastic clips. Just remember they’re there should you drag the Coaster up on shore.

Stable, Recreational Ride

Retrospec Coaster Inflatable Kayak Stability



Hauling the roughly 30-pound Coaster to water’s edge is aided by handholds fore and aft, as well as center. Gear can be loaded up under both forward and aft bungees, as well as tucked into the little nooks below the splash guards. The exterior is also pretty pet-friendly for those that prefer not to leave Fido on shore.

Underway, we were impressed by the Coaster’s overall stability and handing. No, it doesn’t have the more precise feel of a higher-end model with more rigid floor construction, but that’s not the Coaster’s audience. This is a craft targeted mainly at the recreational, casual kayaking enthusiast who appreciates the portability of a model that folds up into a compact, albeit somewhat heavy backpack.

Its trio of fins provided solid tracking. The interior is also wide…and comfy. Inflatable seats, inflatable floor and inflatable hull sides add up to a somewhat cushy, relaxing feel. Rougher, choppier conditions are softened by those same inflatable parts, but also reveal a little bit of flex. Best to stay in calmer waters. Overall, however, we felt comfortable and secure. The Coaster glides atop the water better than expected, was easy to maneuver, and handles a decent amount of gear.

When it comes time to pack away, a plug on the lower cover can release water that gets in between cover and bladders, but the fabric itself is not especially fast to dry. Those that want to pack up quickly will find they have to put the kayak away damp or leave it for a good amount of time in the hot sun to fully dry. Packing up, however, is a pretty simple process, which is how it should be.

The Last Word

Retrospec Coaster Inflatable Kayak Action


Retrospec has put together a nice recreational package with the Coaster. It is a beginner and intermediate-friendly ride that’s affordable, easy to transport, hauls some extra gear and, at least in the eyes of this beholder, looks great.

Speaking of the latter, we failed to mention one other plus — it comes in three distinct color combos. Choose your favorite and get your paddle on.

In addition to inflatable kayaks, Retrospec also offers a variety of other inflatables and water gear, including inflatable paddle boards, kids’ paddle boards, inflatable platforms, paddle board accessories, life jackets, and more. Choose your favorite and get your paddle on.
