WHITEWATER SERIES BASIC SETUP (Including Self Bailer)
Seat Installation - All Whitewater Series models include a 3/4-length inflatable seat and Whitewater Foot Brace. The Alpackalypse Seats are 3-inches thick and the Gnarwhal Seats are either 5-inches (decked) or 7-inches (self bailer) thick. The seats are installed valve side up and held in place by a sleeve welded to the floor of the packraft. The Whitewater Foot Brace attaches to a red 1-inch webbing grab loop installed in the floor of the packraft towards the bow with the valve side up.
Backband Installation - All Whitewater Series models come standard with a backband. The Gnarwhal comes with a custom foam backband, which is installed by: (i) attaching the stabilizer straps to the strap plates in the stern and rethreading to the inner ladder locks on the back of the backband; and (ii) threading the main backband straps through the rear facing D-Rings from front to rear, then back through the aluminum common loop and the outer ladder locks on the back of the backband. Adjust the backband for fit and then tighten the stabilizer straps to hold in place. The Alpackalypse Backband is inflatable and does not include stabilizer straps. Installation to the D-Rings is the same as the Gnarwhal backband.
Thigh Strap Installation - All Whitewater Series models come standard with patent-pending 4-point adjustable thigh straps. The ankle and hip attachment points are each adjustable in length to tighten the strap and change the placement of the strap over the knee. The two top (C/D) attachment points are adjustable both in length and in placement depending on the boater’s knee position. See the Thigh Strap and Backband Setup instructions in this manual for more details.
NOTE - One of the most important considerations in using your packraft is the way it feels to you - how comfortably it fits and how easy it is to enter and exit. Do not overtighten your thigh straps and backband as it could impair your ability to exit the boat.
Inflating - All Whitewater Series models feature a lightweight single valve allows high pressure oral inflation and quick deflation with a quick twist of the valve core. Turning the valve core to the right will open the valve for deflation and turning the core to the left will allow the one-way flap to engage for tempering. To inflate, insert the valve adapter on the inflation bag into the valve and twist to the right to lock in place. Use the inflation bag to capture air and compress it through the valve (see the inflation bag video on our website for more details). As the boat fills up, you may want to turn the valve core to the left (without disengaging the adapter) to close the one way flap which will allow you to get more air in with the inflation bag. When the boat is full, disconnect the valve adapter and proceed to tempering.
Tempering - Unlike a spring valve used in larger rafts, our valve is designed with a very light action 1-way flap to allow the boat to be orally tempered. Note that the light action 1-way flap will not engage until you have orally added some pressure to the raft. The amount of air pressure that you choose to use is personal, but we recommend approximately 1.2-2.0 psi which is the max that a normal person can orally add into the boat. Be careful not to exceed 2.0psi if you are using a pump. After tempering, screw on the valve cap to prevent any leakage while boating. NOTE - LEAVING YOUR ALPACKA RAFT IN THE SUN UNATTENDED CAN CAUSE THE AIR PRESSURE IN THE CHAMBER TO RAPIDLY RISE, WHICH CAN LEAD TO FAILURE OR PERMANENT DAMAGE. ALWAYS LET SOME AIR OUT YOUR BOAT AND SEATS BEFORE TAKING A BREAK FROM THE WATER IN THE SUN.
Deflating and Folding/Rolling- To deflate, remove the valve cap and twist the valve core to the right. Once the packraft has been de-tempered with the valve you can open the Cargo Fly zipper to release the rest of the air. There is no right or wrong way to roll or fold your boat for transport. Do whatever fits best for your use and carrying method.
