Build and Defend Your Raft — Best Defense Guide
Defense Updated 2026-09-03

Best Defense Guide

Loot is the whole game: you collect it, raiders steal it. This guide ranks every defense tool by what it actually prevents and assembles the pieces into layouts that survive contact with a real raid. For piece-by-piece mechanics see the cannons and turrets guides; for the panic buttons see lock & shield.

Defense priority: what actually keeps loot

Ranked by real raid outcomes, not by how scary pieces look:

Rank Defense What it stops
1 Chest placement The only “defense” that can’t be outgunned — a chest deep inside can’t be grabbed in a drive-by
2 Closed wall ring + one door Most raids are opportunistic; a closed ring makes them move on
3 Reinforced walls Low-level cannons struggle vs even wood walls; reinforced shrugs off broadsides
4 Automatic cannons Perimeter denial — forces raiders to commit or flee
5 Turrets Boarding crews die on the deck instead of in your hallway
6 Nets (as defense) Passively re-earn what raids cost you
7 Lock Raft / Shield Emergency only — cooldowns mean they can’t be your plan
8 Spikes, fences, flags, towers Deterrence and cosmetics; spikes slow but don’t stop

The chest room is the actual game

Every defense exists to buy time for one thing: making your chest hard to reach. Raiders can carry the entire chest off your raft — so the design goal is maximizing the distance and doors between the water and your chest.

The proven chest room pattern:

  1. Center of the raft, or upper deck with reinforced stairs.
  2. Reinforced walls on every side, one reinforced door.
  3. A turret covering the approach.
  4. Nothing valuable displayed on outer decks — that’s bait furniture.

Layout archetypes

The Box (solo players). Square deck, full wall ring, single door, cannons on two open corners, chest in the middle. Boring, effective, cheap to repair.

The Fortress (crews). Two decks: ground floor with cannons and turrets, upper deck with the chest room behind reinforced stairs. One player drives, one shoots, one guards the vault. This is the hour-100 raft from the promo art in functional form.

The Decoy (raiders). Deliberately scruffy outside, turrets and cannon broadside inside. Looks like a free lunch; boards into an ambush. High risk, high entertainment.

What raiders actually exploit

Audit your raft the way an attacker would:

  • Count your doors. Every extra door is a planned entry route for someone else. One player found an opponent’s spare doors detachable mid-raid — attackers will open your raft from the inside.
  • Check your cannon sightlines. Your own walls take cannons out of the fight. If a cannon can’t see open water, it’s decoration.
  • Look for the uncovered side. Raiders circle and enter from the flank with no cannon silhouette.
  • Mind your ladders and stairs. A second floor with no hatch control drops defenders on your head — or you on theirs.

Video walkthrough — The hour-100 raft in this video is the fortress archetype in action: closed rings, elevated decks and cannons with clear water view.

## After every Saturday patch

The dev ships updates weekly and hotfixes near-daily. Defensive metas shift when wall HP, cannon damage or snap points change. The post-patch ritual: screenshot your raft before updating, then walk the ring, open the Crafting Table, and test-fire one cannon. See the updates page for the current patch timeline.
