Once there, to my amazement, the Coasties brought the boat through the surf and one of them, Dave, jumped onto the rocks. He helped my wife into a survival suit. She was spent, and collapsed on the rocks, crying with relief. Yet, we were far from being done. Dave had made it onto our rock with great skill, but it was decided it was too risky for us to jump from there to the boat. We climbed back to the beach, and slowly made our way to a place on the east side of the cove. There, we timed our jumps to land in the Zodiac after it rose nearly eight feet to touch the rocks at the crest of a wave. With all of us aboard, we had a wild ride through the six-foot surf before we finally made it to safety. Upon our arrival at Tofino, Theresa was taken to the local hospital, were she was treated for mild hypothermia. The next day, conditions had finally calmed down. We took the Coast Guard some breakfast in appreciation of our rescue, and to inquire about hiring someone to take us back to salvage our gear. Without hesitation, they offered to take us back to the beach.The Weilemans live in Tacoma, WA, where Steve is a system network engineer.


Lessons Learned
by Christopher Cunningham

When I first read Steve's story, I had a hard time making sense of it. After all, Steve and Theresa, in spite of some very rough going, had made it to shore with all of their gear intact. They had shelter, plenty of food and water, everything they needed to sit out the storm. I couldn't understand how they could get to a point at which they would need a rescue. A couple of the pieces of the story didn't make sense. The first was their complaint that they couldn't get any sleep, even though it was only mid-morning. The second was how much time passed during the day without their doing much. I didn't understand why they didn't make more of an effort to find a spot that was better protected from the wind and rain. Then, as I worked with Steve on the story, he mentioned that he had had trouble doing simple mathematics to determine whether or not the tide would rise to the level of their camp. I then realized that hypothermia had been a factor at a very early point in their experience. Usually, when we look at hypothermia in the context of a paddling incident, someone winds up in the water, and the onset of the symptoms of hypothermia is sudden and dramatic. Certainly Steve and Theresa were at risk for this sort of problem-they found themselves paddling in conditions that put them well beyond the previous limits of their paddling abilities and at risk of a capsize in clothing that would not have protected them from the cold water. Fortunately, however, they both managed to stay upright in their boats and made it to shore.

They had a tent, dry clothes, sleeping bags and plenty of food and water. The air temperature was a relatively mild 58°. Yet, within 24 hours of their coming to shore, Theresa's deteriorating condition warranted an evacuation. The Weilemans had burned up a lot of calories paddling from Ahous Point to the shelter of the cove west of Moser Point. Not only did they expend a lot of energy in their efforts to keep upright and move their boats forward, they lost a lot of energy in the generation of heat, an inevitable by-product of strenuous exertion. When they reached shore, they were exhausted. Setting up camp in winds of up to 40 knots and heavy rain, they continued to lose heat. Our bodies operate on an energy budget. The cost of the exertion and the heat is fuel. You may have heard of this in the context of the repercussions of disturbing coastal fauna: Animals that take to the water or the air at the approach of a kayak use up energy; if their food supplies are scarce, their chances for survival may be reduced. We, too, need to replace the calories we have metabolized in order to keep our strength up. Given the cargo capacity of a kayak, it is usually easy to carry enough food to provide the energy we need to meet the demands of paddling and camping. The task then is to balance the calories burned up with the calories taken in. Comfort is a good indicator of how well you are maintaining that balance. You need to drink before you get thirsty. The feeling of thirst is an indication that you are already somewhat dehydrated. The same could be said of food and of warmth. Eat before you get hungry, and put on extra clothing before you feel chilled. If you can achieve and maintain a level of comfort even in challenging conditions, you are better able to perform well and to avoid the serious consequences of the onset of hypothermia.

After Steve and Theresa had set up camp, Steve had held to the idea that the storm would let up. The guidebooks that he'd read noted that there were often stiff breezes in the afternoon, followed by calm conditions in the morning. If they could wait it out, eventually the weather would improve and they could get back to the normal activities like cooking and eating. Unfortunately, the wind and rain were the product of a storm system that had caught the forecasters by surprise. It would last much longer than the local afternoon winds. Regardless of how long they might have had to wait for an improvement in the weather, they could not afford to remain cold. The discomfort of being chilled should have been their cue to reevaluate and improve their circumstances. The dense underbrush at the edge of the woods was a deterrent to moving their camp away from the beach, but it could have created an effective windbreak if they had made their way through it to set up camp. Protected by the trees and brush, they might have been able to break out their stove to prepare hot food and drink. They might also have found or made a small clearing for their tent. Exposed to the force of the wind on the beach, the tent was not keeping them warm or dry. Rainwater leaking through the zippers was pooling on the floor of the tent, and the constant pulsing of the tent walls was circulating cold air, further chilling them. Without food and water to replace the fuel they had expended, the Weilemans continued to lose heat. Once the available calories had been burned off, the heat would be drained from their bodies.

Steve, at 6'3" and 220 pounds, had a larger heat mass, so it is not surprising that Theresa, at 5'2" and 125 pounds, would be the first to succumb to the cold. Theresa, described by Steve as strong and adventurous, withdrew into her sleeping bag. That might seem like a normal response to the effort she had made paddling that morning, but "hypothermia is easily overlooked in the wilderness, and has been mistaken for fatigue"*. By the time she crawled into her sleeping bag, she didn't have the fuel to generate more heat. The insulating property of her sleeping bag would only help her maintain her body temperature, which was already low, but it wouldn't return her to normal. Steve checked in with Theresa frequently, but he took her at her word that she was OK. A more specific line of questioning might have given Steve a more accurate assessment of Theresa's condition: Are you warm? Are you dry? When is the last time you had something to eat? Theresa needed food and water and/or heat from an outside source. Steve might have zipped their sleeping bags together and crawled in with Theresa to serve as a heat donor, but he was probably running out of fuel too. To generate enough heat to help rewarm Theresa, Steve would have needed to be at a normal temperature and well fed. Without the calories to "donate" to Theresa, he would have only worsened his own hypothermia. Steve was not aware that he, too, was hypothermic. He found it increasingly difficult to concentrate on small tasks as he tended to the tent and the kayaks. "Mental functions tend to go first . . . The diminished intellectual response evident in early stages of hypothermia dangerously impairs our ability to react to the environment."* The loss of mental function is the most compelling reason to manage your energy budget well: Once you start to get hypothermic, you may not realize that you have a serious problem to address.

Steve did a good job of tending to the tent and the kayaks. He kept active, but he did not realize the growing seriousness of their condition. When Theresa became less communicative, a symptom of moderate hypothermia, Steve realized that something was wrong. He then discovered that she was cold and wet. Even though Theresa had been telling Steve that she was OK, she probably had been aware all along that her sleeping bag was wet. Apathy and an improper response to cold are also symptoms of hypothermia. Steve was well advised to contact the Coast Guard at that point. As it turned out, the storm would last another day. Fortunately, his VHF radio had enough power to make the distress call. His VHF was six years old, and equipped only with a single rechargeable battery. During the trip, he had used the radio only to check weather reports. Once he made the distress call, he established times to check in with Tofino. Despite the measures taken to conserve battery life, the battery went dead and Steve was no longer able to transmit. A number of new radios have optional alkaline battery packs that provide backup power when the rechargeable battery dies. By the time Steve's radio battery failed, the rescue was already underway and the Weilemans were picked up and taken to the hospital for treatment. While the main concern was for Theresa's condition, Steve was also treated for hypothermia. To his surprise, his temperature was lower than Theresa's. It wasn't until after the rescue that Steve realized that he, too, had become hypothermic, and that his ability to respond properly to the cold had been diminished.
