Agile Self-Bailing Whitewater Packraft
The MRS Viking EVO is a premium self-bailing whitewater packraft designed for rapid drainage and continuous action. Instead of trapping the paddler under a restrictive spray deck, the Viking EVO utilizes a thick inflatable floor and strategically placed drain holes to shed water instantly. This open-top design makes it the ultimate boat for technical rivers that require frequent scouting, portaging, and quick cockpit access.
The drainage holes are concentrated under the paddler’s heels and equipped with shielding plates that reduce drag — addressing the slow response that has long limited self-bailing packrafts. Paddlers familiar with traditional self-bailers will notice the difference immediately.

Care & Maintenance
- Heat Expansion: Air expands rapidly under heat. Never leave a fully inflated packraft sitting on shore in direct sunlight. Always release the valve on the packraft, seats, and backrests when out of the water to prevent pressure blowouts and seam stress.
- Freshwater Rinse: Always rinse the hull thoroughly with clean freshwater after paddling in saltwater, silty rivers, or sandy environments. Rinse the self-bailing floor and drainage holes after use in silty or muddy water to keep them clear.
- Floor Crevice Cleaning: Sand and gravel can get trapped between the inflatable floor and the outer tubes. Deflate the boat slightly and flush these crevices with water to prevent the grit from acting like sandpaper against the TPU.
- ISS (TiZip) Care: Keep the zipper teeth meticulously clean. Before every trip, clear away sand with a soft brush and apply the included silicone lubricant to the zipper dock to maintain an airtight seal. Always ensure the zipper is fully closed before inflation. See our TiZip maintenance guide for full care instructions.
- Complete Drying: Never pack a wet raft away for long-term storage. Wipe it down with a towel and let it air dry completely in the shade to prevent mold, mildew, and polyurethane degradation. This is especially critical to prevent the TiZip from leaking.
- Climate-Controlled Storage: Store the deflated boat loosely rolled in a cool, dry place away from direct heat sources, extreme freezing temperatures, and harsh chemicals.
Performance Tips
- Cold Water Tempering: Air is highly sensitive to temperature. When transferring an inflated packraft from land into cold water, the internal air will condense and soften the tubes — this is normal, not a leak. Let the boat sit in the water for two minutes, then top off the pressure with a pump until the chambers feel firm again.
- Weight Distribution: To maximize hull speed and reduce side-to-side "yaw", distribute weight evenly. Heavy gear should be placed forward, as it helps lock the raft into a straight line.
- Skeg Installation: Always insert the tracking fin before fully inflating the boat. Using a skeg drastically improves forward paddling efficiency and reduces yaw. Choose the small skeg for whitewater maneuverability, or the large skeg for optimal straight-line tracking on open lakes and long river stretches.
- Seat: To enhance comfort, the seat cushion’s air pressure can be reduced — this lowers the seat height and lets it conform better to the body, also improving backrest support.
- Thigh Straps: Aggressively tension the thigh straps and adjust the backband before hitting rapids. A locked-in, tight fit is required for precise control.
- Drainage: The redesigned drainage floor has very low starting resistance — expect more agile starts/stops than traditional self-bailers. When entering calm water from rapids, some water will naturally sit in the floor; keep your weight centered to allow the drain holes to function efficiently.
- Comfort & Insulation: If you are paddling in cold water, we highly recommend wearing neoprene socks or paddling booties to retain body heat.
Warranty
- 3-Year Guarantee: Every MRS packraft includes a 3-year warranty against material and manufacturing defects.
- Zipper Coverage: ISS (TiZip) zippers are warranted separately for 1 year.
- US-Based Support: All inspections, claims, and support are handled directly from our California facility for fast, hassle-free service.
Internal Storage System (ISS Models)
Available on Viking EVO ISS models only.
Instructions for Use
1. Distribute weight evenly between the two storage bags. Because the bags cannot be accessed until the packraft is deflated, only store items that you will not need on the water.
2. Place your gear in the storage bag, fold the top closed, tighten as much as possible, and then insert the buckle at the top opening.
3. Open the TIZIP zipper and slide the storage bag into the packraft tube.
4. Once the storage bag is inside the tube, unfasten the top buckle, pass the strap through the two tie-downs, and re-fasten the buckle.
Tie-down fixings inside the tubes secure the storage bags in place, so they will not slide back and forth as the packraft moves.
FAQ
What is the Viking EVO best for?
The Viking EVO is best for technical Class II–IV whitewater, creeking, and frequent eddy-in / eddy-out runs. Its full self-bailing floor drains the cockpit continuously between rapids, making it well suited to whitewater training and multi-day expedition runs.
What is a self-bailing packraft?
A self-bailing packraft is designed with a thick, inflatable floor and strategically placed drain holes in the hull floor. When water splashes into the boat from rapids or waves, it immediately drains out through the bottom. This prevents the raft from swamping, ensuring it remains highly buoyant and maneuverable in heavy whitewater.
What is the main difference between a self-bailing packraft and a regular packraft?
The primary difference lies in water management and structural weight.
Self-Bailers: Let water in but drain it out constantly. They require an inflatable floor to elevate the paddler above the drain holes, which adds a slight amount of weight but allows for incredibly fast entry, exit, and self-rescue.
Regular Packrafts (Open or Spray Deck): Designed to keep water out entirely. They use a standard single-layer floor, making them lighter and easier to pack down. If a regular open boat swamps, it must be manually flipped and dumped.
Do you get wet in a self-bailing packraft?
Yes. Because a self-bailer relies on open holes to drain water, a small amount of water will always be present on the floor. Your lower body will get wet. For this reason, paddlers using self-bailing MRS packrafts in cold environments must wear appropriate thermal protection, such as a drysuit or wetsuit.
What makes the Viking EVO's self-bailing floor different?
The Viking EVO's redesign concentrates the drainage holes under the paddler's heels and adds shielding plates to reduce drag, making it more agile and faster-responding than traditional self-bailers. After a wave breaks over the bow, the cockpit empties on its own — no need to pull over and bail.
How does the Viking EVO compare to the standard Viking and the Alligator?
The standard Viking Self Bailer uses 11 drainage holes plus a baffle plate and the older floor design. The Viking EVO uses the redesigned high-drainage floor with shielding plates, plus 420D Pro-tier hull fabric. The sealed-deck Alligator keeps water out via the spraydeck instead of draining it through the floor.
What is the zipper on the seat for?
The Viking EVO seat carries a TiZip zipper on the seat bladder that serves two purposes: it allows easy maintenance and access to the seat’s air chamber, and it provides roughly 5 L of dry storage inside the seat. This seat zipper is separate from the hull’s Internal Storage System and is fitted on every Viking EVO.
Where is the ISS TiZip opening located?
On ISS models the hull TiZip is on the rear of the raft; when the zipper is closed, the pull tab sits at the far end, so it is easy to miss in photos. This is distinct from the seat-bladder zipper — the rear hull zipper is the access point for sliding the internal storage dry bags into the tubes.
Can I add a removable deck or spray skirt for cold-weather paddling?
No — the Viking EVO is a self-bailing model and is not equipped with a removable deck. Because the floor drain holes let water in by design, a deck would not keep the cockpit dry, so it offers no benefit on a self-bailer. For cold-water comfort, wear a drysuit or wetsuit with neoprene socks rather than relying on a deck; the EVO’s single drain area near the feet can be temporarily taped for a drier ride on flat sections.
