Last Harbor Guide
Last Harbor PvP guide
How PvP works in Last Harbor — hostile boats, claim rules, raid windows, and how to defend your floating base from other players.
Last Harbor's PvP is built on a consent-based raid system. You can damage other players' boats and island bases, but doing so costs you — a raid flag that makes you visible on the map for 30 minutes. This guide explains how the system works and how to win in PvP without losing your loot.
How PvP works
PvP damage in Last Harbor is opt-in. When you damage another player's boat or base, you receive a raid flag that makes you visible on the map for 30 minutes. Other players can see you coming, and the raided player gets a notification. This is a deliberate design choice to prevent drive-by griefing and reward coordinated raids.
Claim rules
You cannot raid the same crew twice in a 4-hour window. This is to prevent death-spiral raiding where one crew is repeatedly wiped. The 4-hour window is server-wide, so even a different player in the same crew counts.
Raid windows
Most servers have a 3-hour daily window where PvP damage to boats is disabled — typically 03:00–06:00 server time. This is the off-hours protection. Use it to repair, refuel and resupply without being attacked.
Safe harbors
Certain islands are designated as safe harbors. You cannot damage a boat that is anchored in a safe harbor. The standard safe harbors are the small fishing islets on the outer ring. Use them to log off, but they have minimal loot, so don't expect to do a full scavenge run from one.
How to raid
The meta raid composition is 3+ players on a Tier-2 or better boat with at least one deck cannon and one harpoon launcher. Approach from downwind, drop the raid flag intentionally (it's going to happen anyway), close to harpoon range, and harpoon the enemy boat to slow it. Then broadside with the deck cannon.
How to defend
Speed > defenses. If you see a raid flag approaching, sail. You can outrun almost any hostile boat in a Tier-2 or better hull. If you must stand and fight, kite them around a kelp bed or a sunken boat — the debris will catch their harpoon. Never anchor in open water on a PvP server.

- Off-hours protection is typically 03:00–06:00 server time
- Safe harbors cannot be raided
- Speed is the best defense
