Introduction to Class V

Welcome to Class V; the ultimate challenge in white water rafting! We at Sierra Mac are excited to share this thrilling adventure with you. As you contemplate taking a Class V trip, it is imperative to realize that these trips are intense and demanding passenger participation experiences, and that a successful run depends upon you and your boat team (First time rafters do very well, when they follow instructions and perform the calls of the guide). Our training covers everything you will need to know to be a successful paddler on Cherry Creek.

Class V rafting requires, especially, that participants be agile and able to move quickly on their haunches to the “high side” to prevent capsizing. Flips are rare on Cherry Creek. While you need not be an athlete to participate, good physical condition is naturally required. Class V rafters typically jog, play tennis, ski, swim, do aerobics, bicycle, backpack, etc. on a regular basis in order to maintain their good physical condition. Squats are very helpful to prepare, we “GET DOWN” a lot throughout the trip to prevent accidental swims.

Previous rafting experience is not required. Each Class V trip begins with an intensive white water training seminar which includes training in swiftwater swimming, class 5 paddling and safety techniques. The pre-trip seminar can give you the training necessary to respond quickly and appropriately to the demands of the trip; your endurance and your ability to follow instructions are, however, your own responsibility.

In deciding to take a Class V white water rafting trip, you are acting to put yourself at some risk. You will be required to sign a statement releasing Sierra Mac River Trips from liability for any injury you may sustain during the trip.

The likelihood of injury is small. The following information is intended to help you better identify and understand the risks and how to avoid them. We have never had a serious injury while rafting the Tuolumne River or Class V runs on Cherry Creek/Upper Tuolunme. In the past two years (2021, 2022), we have run over 80 commercial trips. Our team often trains during days off. Our guides have an average of more than ten years of professional white water guiding experience (Our Creek guides have over 15 years average experience on the Creek). We hope that you will have a great time on your river trip with us!

Safety Techniques

Safety is our first concern, and it should be yours, too. The foremost key to safety is avoiding any situation where you may be held underwater. Following the guidelines below and the instructions during the pre-trip training seminar will minimize this possibility:

While you are in the boat, keep free of lines and ropes. In the unlikely event that the boat turns over, you need to be able to get free from it and swim away.

If you fall out of the raft in the middle of a rapid, don’t panic. It’s natural to be scared, but you need to focus on what you must do to help yourself to a place of safety. Panicky behavior accelerates your consumption of oxygen and diminishes your ability to aid in your own rescue. Conserve your energy for the time it will be needed most for your exit to a safe place.

Self-Rescue, your ability to get out of the river correlates with the length of time you are in the river. Actively identifying and pursuing a path out of the current is very helpful during a big swim in a rapid. A defensive position is better when you can’t work on getting out of the river and are tumbling down whitewater drops.

Adopt the best defensive position for navigating through the rapids: floating on your back, keeping your feet up and pointing them downstream, and staying away from submerged trees, bushes and boulder strainers. By keeping your feet up, you prevent them from being trapped by the rocks on the river bottom. By pointing your feet downstream, you make them the first point of impact with any rocks that you may encounter along the way. When confronting a strainer on top of the water (tree branches or rocks), you will want to turn and face the obstacle in order to climb up onto or through it.

As you float through a rapid, the waves and turbulence may make it impossible for you to breathe at your convenience. The best place to catch a breath is in the troughs of the waves, where the water is calmest. In general, it is best to hold your breath in between good breathing opportunities.

Listen to your guide, and follow instructions. Sticking close to the raft when you fall out is not always the best plan. Getting out of the river is the primary goal. Most notably, avoid a situation where rocks are just downstream and the boat is just upstream of you. In such circumstances you should swim away from the raft in order to avoid becoming sandwiched between the raft and the rock.

Consider how you are going to get back to the raft, or swim to a rocky shore. This can be accomplished in a variety of ways:

Float on your back, keeping your feet up and pointed downstream, looking where you are going until you see a way out of the river; then swim to that boat, shore, eddy or island in the river.

If the conditions at your location remain swift and you perceive hazards downstream, swim to the nearest eddy. (An eddy is a pool of calmer water that sits immediately downstream of a boulder or riverside promontory.) A backstroke or sidestroke enables you to see better any obstacles downstream. Freestyle is recommended for short distances, for greater speed and power.

Receive a throw line or a paddle handle extended by a fellow passenger or a guide, who will pull you towards the raft. If you grab the throw line, don’t grab only the bag, as there may be several feet of rope in the bag that will have to be pulled in ahead of you. This line, as well as any rope, must be considered a potential hazard. Never tie or wrap the line around your wrists or any part of your body, as the line may drag you under water. If it does pull you down, and you are held under water for an extended period of time, you should let go of the line. Otherwise, hold the line over your shoulder and close to your chest while floating face up and away from the thrower. Take a deep breath and hold it; breathe between waves.

Swimming through obstacles known as strainers (trees in the river, or a boulder-choked drop) is a rare event and one of the most dangerous obstacles river runners ever encounter. This requires aggressive maneuvers on your part in order to pass through the obstacle successfully. Your best approach to a strainer is swimming headfirst towards it. Although this goes against the universal “feet downstream, float on your back” swimming position, it is your best position for using your arms to climb on top of; over or through the strainer.

Miscellaneous Tips

ALCOHOL/DRUG Never drink alcohol before or while rafting. Ingesting alcohol or drugs slows your response time and reduces your resistance to cold. If you show up at the meeting place under the influence or wasted from activities you participated in the night before your trip, you won’t be rafting!

ATTENTION Keep your eyes downstream; remain attentive to the river and your guides. Invariably, the rock or wave you don’t see or prepare for will be the one to knock you out of the raft. This doesn’t mean you should stare downstream and miss the beauty of the wilderness around you. It means you should try to be aware of unexpected events and be on the lookout for a stray flying paddle or passenger headed your way.

BEE STINGS, ALLERGIES OR PHYSICAL HANDICAPS If you are allergic to bee stings or have other allergies, physical handicaps, recent surgeries, etc. which might affect your safety or well-being during the trip, please discuss this with our office and your lead guide prior to embarking on the trip. Plan to provide your own medications, and request that the trip leader place them in a secure storage area. Bring extra contacts if you need them to see.

DEHYDRATION The sun and/or your vigorous activity can dry you out, and your electrolytes may become imbalanced. It is very important to drink liquids to rehydrate yourself and balance your electrolytes.

FEET One way to stabilize yourself in the raft is to utilize the foot cups provided on the floor of the raft and/or to wedge your feet under the side tubes or thwarts (cross tubes). Your feet should be flat on the floor of the raft at all times. Shoes are of the utmost importance: they must be securely fastened to your feet and give perimeter protection and grip for slippery surfaces. Sandals and most wet suit booties are not acceptable. Most guides wear sticky rubber closed toed sport shoes and you should, also.

FLIPS The wilder the water, the more likely it is that the raft will turn over. An agile and responsive crew can prevent most turnovers from happening. If your raft does turn over, treat this experience with the same composure you normally reserve for falling out of the raft. You could have an additional concern: you may end up underneath the raft. In this case, swim out from underneath it, preferably upstream (so you won’t end up between the raft and a hard place, like a rock). Do this by pushing up against the raft in order to move yourself deeper, away from the raft, until you exit to the side of it.

HOLES A hole is a place in a river where the river level drops sharply. The main portion of the current follows the river bottom, while the surface current curls back upstream. Swimmers can be trapped in holes and circulate around and around. The strategy for escaping a hole is to swim to the side or the bottom of the hole to catch the downstream current.

HYPOTHERMIA Hypothermia is generally defined as a potentially dangerous loss of body heat. Eat a good breakfast before your trip. Thermal layering of clothes is the best protection from body heat loss. Begin with a thin layer of wool or synthetic fabric to be worn under a full wet suit (below knees to shoulders). Wet suits are mandatory on Class V river runs. The best wet suit for rafting allows freedom of arm movement, protects your knees and is not so thick that it will cause you to overheat. For additional warmth, a rubberized nylon shell over the wet suit works well. (Wet suits & rubberized nylon shells are issued and included on every trip.

LIFE JACKETS/FLOTATION VESTS & HELMETS Always wear your flotation vest and helmet while on the river and when scouting rapids, as well. Check for proper fit of your vest by grasping both shoulders of the jacket and pulling up sharply. The jacket should not rise more than about an inch. Your helmet should be snug around your head, and the strap should be snug under your chin.

HIGH SIDE It may be a natural reaction for a person to back away from a swiftly approaching rock or cresting wave. This reaction is exactly the one you want to avoid, as that shifting will weight the raft on the side away from the rock or wave, thus making the side of impact into a “high side”; the higher that side is, the farther the raft will slide up onto the rock or raise up onto the wave. So, when there is danger of a raft sliding up a rock (and perhaps getting stuck, called “wrapping,” or even flipping over), the guide will call out a “high side” or “get right/left” command, which means you should move over to the appropriate side of the raft and prepare for the shock of impact. In these “clutch” moves you must act quickly and be able to get back to your position for further navigational instructions.

OFF-RIVER HAZARDS Injuries can occur along the banks of the river (the most common injury by far). Take care not to slip and fall, and look out for hazards such as rock slides, poison oak, and rattlesnakes.

Fitness Guidelines

General guidelines to the physical and mental fitness required for participation in Class V rafting:

SWIMMING You need to know how to swim effectively (we make you prove it). You should be able to swim free-style (crawl), kick your feet and keep your head up. The best swimmer we have seen on rafting trips are water-polo players.

HEART Step up and down on a 12-inch box 30 times per minute for three minutes. Sit down and take your pulse for one minute immediately following the test. Your one-minute heart rest-recovery rate should be under 140 beats per minute.

LUNGS Jog 70 to 90 yards on one breath of air. SWIM: Swim 500 to 600 feet without stopping.

MENTAL ADAPTABILITY Follow instructions well. Successfully complete white water training seminar when you arrive at the river.

KNEES Squat 20 times, you should be able to do a full squat while keeping your back mostly straight. If your knees are bad, you may not be able to “GET DOWN” appropriately

SELF ASSESSMENT Score yourself (ideal =10; average = 5; maximum score is 100).
