Shipwreck Raft Build

Name and Purpose

Shipwreck Raft Build is an adventure-based team challenge that blends navigation, problem-solving, and creative construction.
Players practise leadership, communication, and resourcefulness as they move through a multi-stage outdoor challenge and build something together under time pressure.

a.k.a.

Age / Group / Time / Space

Ages 10-16 | 10-40 players in teams of 4-6 | 45-90 minutes | Large outdoor area with varied terrain for navigation; flat staging area for raft building; indoor backup possible for the build stage

Materials

Navigation task cards: one set per team (staff-created; can use landmarks, compass directions, or GPS if devices are available)
Raft-building materials per team: cardboard sheets, rope lengths, pool noodles, tape, and any reusable camp materials available
Storyline briefing sheet per team (1 page)
Optional: printed maps, compass per team, or landmark clue sheets
Boundary markers (cones or flags) for the navigation area
Timer or whistle for stage transitions
Staff at each navigation checkpoint (minimum 1 per checkpoint)

Quick-Run Card

Brief teams on the scenario: your GPS rally has ended in a simulated shipwreck on a mysterious island.
Teams follow navigation task cards to reach each checkpoint in order.
At each checkpoint, teams collect a piece of their raft-building kit.
At the final checkpoint, teams have a set time (20-30 minutes) to build a raft structure.
Raft designs are reviewed against the brief: does it meet the criteria, and how did the team work together?

Setup and Boundaries

Map out a navigation route with 3-5 checkpoints across the outdoor area before play
Place one staff member or a sealed clue envelope at each checkpoint
Mark the raft-build staging area clearly with cones
Signal: 1 whistle = teams may move; 2 whistles = pause in place; 3 whistles = gather at staging area
Do a safety sweep of the navigation route before sending teams out: check for uneven ground, low branches, water hazards, bee nests, and sun exposure
Ensure all teams have water bottles before departing the start point

How to Play

Divide into teams of 4-6. Give each team their storyline briefing sheet and navigation task card set.
Teams move through the navigation route, solving clues or following directions to reach each checkpoint in order.
At each checkpoint, teams collect one component of their raft-building kit (a length of rope, a pool noodle, a cardboard sheet, etc.).
Teams who arrive at a checkpoint out of order wait there until the correct checkpoint sequence is confirmed.
Once all teams reach the final checkpoint, the timed raft-build begins. Teams have 20-30 minutes (staff set the time based on group age and complexity).
The raft brief: the structure must be able to symbolically hold 3 team members standing on it simultaneously. It does not need to float.
At time, teams present their raft to the group. Celebration and reflection follow . no single winner; all teams are recognised.

I-OPt Options

A (Active): Lead the navigation, scout ahead, or take the structural lead in the raft build
S (Support): Carry materials, manage the team’s kit, encourage teammates during the build
Q (Quiet): Work methodically on one section of the raft, focusing on detail and precision
O (Observer): Document the team’s journey (notes, sketches), act as timekeeper, or assist a staff checkpoint

Inclusion Adaptations

Navigation task cards can include visual landmarks alongside written clues for players with reading differences
The raft-build phase allows diverse roles: designer, builder, materials manager, and spokesperson for the presentation

Stewardship Moment

All raft-building materials should be sourced from reusable camp supplies, not purchased single-use items
At the end of the build, teams dismantle their raft and sort materials for reuse, recycling, or return to storage
Prompt: “Our island adventure used what we already had. How does that change the way you think about what you actually need to solve a problem?”

Consent

Pre-brief: “This challenge involves moving through the outdoor area as a team and working together under a time limit. For those not comfortable with the outdoor navigation section, joining the raft-build staging team from the start is another option . you’ll help prepare materials and set up the build zone.”
Mid-game check: At the first checkpoint, staff check in briefly with each team. “How is everyone doing? Any adjustments to pace or roles?”
Opt-out/re-entry: Any player can return to the staging area with a staff escort at any point. They rejoin their team for the raft-build phase.

Risks and Mitigation

Uneven outdoor terrain: staff walk the navigation route before play; flag any hazards at checkpoint briefings
Sun and heat exposure during navigation: all players carry water; navigation stage limited to 30-40 minutes maximum; sun hats recommended
Teams becoming lost or separated: each team has a staff contact whistle code; no team proceeds past a checkpoint without checking in
Raft-build materials causing splinters or sharp edges: use smooth-edged cardboard and foam; avoid bare wood or wire; staff inspect materials before distribution
One team finishing navigation much faster than others: have a bonus challenge card ready for fast finishers (e.g., build a shelter or create a team flag)

Warm-Up Suggestions

“Island Story”: gather teams and read the briefing sheet together dramatically to set the mood
“Compass Warm-Up”: teams practise identifying four cardinal directions in the staging area before departing

Debrief Questions

What? “What was the hardest moment in the navigation or the build? How did your team handle it?”
So What? “What did you learn about how your team makes decisions when time is short?”
Now What? “What would you do differently if you had to do this again tomorrow?”
