Extreme Battleship

Name and Purpose

Extreme Battleship turns the pool into a fleet battle using floating vessels and water-based ammo.
Players build teamwork, strategic thinking, and physical coordination in a high-energy aquatic setting.

Age / Group / Time / Space

Ages 10-17 | 10-30 players | 20-40 minutes | Swimming pool with lifeguard on duty; pool deck available for observers and re-entry

Materials

Quick-Run Card

Assign vessel types to each small crew and explain each vessel’s movement rules and ammo.
Teams set up at opposite ends of the pool in their start zones.
On the whistle, teams manoeuvre their vessels and use their assigned ammo type only.
A crew member is “out” for 60 seconds when hit; they move to the pool deck and do a fun challenge before re-entering.
Play to a set time limit; tally hits. The team with the most hits wins.

Setup and Boundaries

Lifeguard must be in position before any player enters the water; no exceptions
Mark pool deck start zones with cones before play begins
Signal: lifeguard whistle = full stop; all players freeze and look to lifeguard
No diving; shallow-end players must stay in water they can stand in unless wearing flotation
Staff ratio: at least 1 staff in the water per 8 players, plus lifeguard on deck

How to Play

Divide players into crews of 1-5. Assign each crew a vessel type: battleship (inner tube), destroyer (boogie board), aircraft carrier (large inflatable), PT boat (pool noodle), or submarine (partially submerged inflatable).
Each vessel type uses specific ammo: battleships and submarines use soft water balls; aircraft carriers use inflatable balls; PT boats use water pistols.
On the start signal, crews manoeuvre their vessel to hit opposing crew members with their assigned ammo.
When a crew member is hit, they move to the pool deck for a 60-second active break (e.g., 10 jumping jacks or a trivia question from a staff member), then re-enter.
Staff count hits throughout; share scores after each round.
Play 2-3 rounds of 8-10 minutes each, rotating vessel types between rounds so everyone tries a different role.

I-OPt Options

Start:
- A (Active): Join a vessel crew and manoeuvre in the water
- S (Support): Help launch vessels from the pool deck, hand out ammo
- Q (Quiet): Take the submarine role (lower movement, more strategy)
- O (Observer): Watch round one from the pool deck, choose a vessel for round two
Mid:
- A (Active): Switch ammo roles within your crew; try a different position on the vessel
- S (Support): Be the crew caller, directing movement from your position
- Q (Quiet): Focus on defence and evasion rather than attacking
- O (Observer): Keep score on the pool deck; join a crew for the next round
Late:
- A (Active): Lead your crew’s final push in the last two minutes
- S (Support): Reload ammo for teammates
- Q (Quiet): Stay in your vessel’s defence zone
- O (Observer): Call out hit counts from the deck; join if ready
End:
- A (Active): Help retrieve floating equipment from the pool
- S (Support): Pass equipment to deck staff
- Q (Quiet): Count and sort ammo on the deck
- O (Observer): Share one observation about a team’s strategy

Inclusion Adaptations

Players who use flotation aids participate fully; assign them to inner tube battleships where support is built in
Pool deck crew roles (ammo supplier, scorekeeper, caller) are full participants, not sideline roles
Water blasters with larger triggers or grip adaptations available for players with fine motor differences

Stewardship Moment

Water balls and blasters are rinsed and stored after play; nothing disposable is used
Prompt: “We chose soft water balls instead of water balloons today. What difference does that make for our pool and our cleanup?”

Consent

Pre-brief: “This game involves water contact and manoeuvring floating equipment in the pool. For those not comfortable being in the deep end, pool deck crew roles and shallow-end vessels are another option. You choose your vessel.”
Mid-game check: after the first round, pause on deck. “Thumbs up, sideways, or down. How is the game feeling? Any changes needed?”
Opt-out/re-entry: signal to the nearest staff member to move to a pool deck role at any time; re-enter a vessel at the start of any new round

Risks and Mitigation

Collision between vessels: set clear lane rules; no ramming; vessels pass around each other
Player separated from vessel in deep water: all players in deep water must be able to swim independently or wear flotation; lifeguard monitors continuously
Water blasters aimed at faces: remind players that ammo targets the body, not the head; staff reinforce this in the first minute
Inflatable deflation mid-game: check all inflatables before play; have a hand pump on deck

Warm-Up Suggestions

“Vessel Parade”: each crew walks their vessel to their start zone while calling out their vessel name; gets everyone oriented
“Noodle Balance”: each player balances on a pool noodle for 30 seconds to get comfortable with buoyancy before the game starts

Debrief Questions

What? “Which vessel type was hardest to manoeuvre? Which had the best ammo?”
So What? “How did your crew decide who did what? What worked?”
Now What? “When do you need to play to your team’s strengths in a real situation?”
