Wind Building, Two Cold Paddlers, One Wet Hatch
Day 2 of a four-day sea-kayak journey on a coastal inlet. Nine students and two instructors are paddling eight single kayaks and one double. At 11:20 am the group is 6 km from the launch point and 9 km short of the planned campsite, on an exposed east-facing shore. The 10:00 am forecast gives NE 15–20 knots, rising to 25 knots with 30-knot gusts by mid-afternoon; air is 12 °C, water 14 °C. Priya and Tom have cold hands and are shivering persistently; Tom has fumbled his spray skirt twice in 15 minutes. One kayak has taken on roughly 4 L of water through its rear hatch over the last hour. The planned campsite is fully exposed to the NE. A sheltered exit beach with 4WD access lies 3 km back; the next sheltered landing ahead is 11 km away.
1. Recommend a course of action for the next 90 minutes and justify it using the specific evidence in the scenario. Identify one piece of information that would change your decision.

Recommendation: turn back to the sheltered beach (3 km) and commit to that decision within 15 minutes.
Reasoning from the evidence
- The casualties are not merely cold. Persistent shivering plus fine-motor failure (Tom fumbling a spray skirt twice in 15 minutes) is a functional deficit, not discomfort. The trend over 15 minutes is more informative than the air temperature.
- The weather is moving against the group. Winds rising to 25 knots with 30-knot gusts within roughly three hours, on an exposed shore. Nine students in chop will not hold 4 km/h; the 9 km to the planned camp is realistically three or more hours of exposure.
- The destination is unusable. The planned campsite is fully exposed to the NE, which is exactly the wind direction. Arriving cold at an unsheltered camp with dwindling daylight is the worst combination available.
- The exit is cheap. 3 km back, sheltered, vehicle access, roughly 45–60 minutes at a reduced pace.
Execution sequence
- Signal a stop; raft up or hold on a sheltered inshore eddy.
- Put a dry layer, hat, and warm drink into both cold paddlers; move one into the double with an instructor if the sea state allows.
- Empty and re-seal the hatch on shore at the first opportunity.
- Paddle back as a tight group with the leaky boat on a short tow or inside line.
What would change the decision: a current observation showing the wind is not building (a sheltered anemometer or a verified reading), or a genuinely sheltered landing within 2 km ahead. Deterioration in Tom's condition (confusion, or shivering that stops) does not change direction - it escalates the urgency and triggers the emergency plan.
2. The group must manage the cold paddlers and the leaking hatch at the same time, with one repair kit and two shelters. Allocate the resources and justify the order of actions.

Triage principle: rank by consequence multiplied by urgency, not by who complains loudest or by what is most visible.
| Problem | Consequence if unmanaged | Urgency | Priority |
|---|---|---|---|
| Two paddlers with functional cold | Loss of paddling ability, then loss of self-rescue, then immersion | Minutes | 1 |
| 4 L ingress per hour | Degraded trim, slower hull, harder to paddle in wind, eventual swamping | Tens of minutes to hours | 2 |
| Group cohesion in rising wind | Scatter, loss of a boat | Immediate but managed by leadership | Overlay on both |
Allocation
- Instructor A + both shelters with the two cold paddlers: land or raft, erect the larger shelter as a windbreak, swap wet layers for dry, hot sweet drink, reassess every 10 minutes. This is the highest-value use of the first ten minutes because it protects the group's capacity to move at all.
- Instructor B + repair kit on the leaking hull once ashore: identify the source (hatch cover seal, missing bungee, cracked rim), apply tape or patch, then assign the paddler a 15-minute water check with a pre-agreed threshold (for example, more than 1 L) that forces a swap into the double.
- A nominated student holds the group in the eddy, counts heads out loud every 10 minutes, and keeps the group facing out of the wind.
Justification: the cold paddlers are the only problem that can remove the group's ability to travel; the hatch only degrades performance. Running the two tasks in parallel, with named responsibility for each, avoids the common failure of the whole group crowding the most dramatic problem while the second one quietly worsens.
3. What would justify activating the emergency plan, and why are those triggers defensible rather than arbitrary?
Read the worked answer
Triggers that justify activation
- Any paddler showing confusion, slurred speech, or shivering that stops - cessation of shivering in a cold, wet person is a deterioration sign, not an improvement.
- Inability to hold a paddle, self-rescue, or maintain a rafted position.
- A person or a boat separated from the group and not accounted for within a set interval.
- Wind sustained above the capability the group has demonstrated in training, not above what the forecast promised.
- Loss of the daylight margin needed to land and establish shelter.
- Any medical situation beyond the group's first-aid scope or supplies.
Why these are defensible
- Observable - each is something a person can see and record, not a feeling.
- Pre-agreed - they were written into the journey plan before departure, so the decision is not invented under stress or negotiated with the loudest voice.
- Tied to capability, not comfort - being cold and miserable is not a trigger; being unable to paddle is. This distinction is what makes the trigger survive scrutiny afterwards.
- Answerable after the fact - the plan should also state who decides, how the call is made (marine radio first where fitted, then phone, then PLB as the last resort), and who is notified on shore. A trigger without a named decision-maker and a named communication method is not a plan.
