Ship Repair covers the mid-combat Repair Kit and Combat Repair Kit system in Windrose. Repair Kits heal 40% hull over 2 minutes but are interrupted by damage; Combat Repair Kits heal 30% over 10 seconds and survive incoming fire. Keelhold hull mod and Naval Tactics III extend heal duration.
Ship Repair covers the mid-combat hull-healing system in Windrose. Three tiers of Repair Kits trade speed for durability: the basic Repair Kit is a slow out-of-combat top-up, the Combat Repair Kit is the standard in-combat heal, and the Master Combat Repair Kit is the Epic upgrade. Behavior changes significantly once Keelhold is installed as the ship's hull modification.
Repair Kit (Uncommon): Dock-adjacent or out-of-combat top-ups only. The 2-minute duration and damage-interruption mean any incoming hit wipes the remaining heal. Useful between fights or while sailing through safe waters.
Combat Repair Kit (Rare): The standard in-combat pick. 30% hull over 10 seconds survives incoming broadsides. Rule of thumb: carry at least one per expected broadside exchange.
Master Combat Repair Kit (Epic): The Epic upgrade. Doubles the heal (60% versus 30%) with the same 10s duration and same damage behavior. The go-to late-game pick once the Epic tier is accessible.
Interaction with Keelhold
Without a hull modification, incoming damage during a Repair Kit reduces its duration. Keelhold changes this completely. At Rare tier, Keelhold removes the damage-interruption penalty entirely; the kit ticks its full duration regardless of incoming fire. At Epic tier, Keelhold also adds +30% duration on top, extending a 10s Combat Repair Kit to effectively 13s.
Keelhold is the repair-focused hull modification, but it is not the only one. Hull Bracing instead leans on raw durability rather than protecting your heals, so a captain who prefers to soak hits over timing repairs may slot it instead. Pick the modification that matches how your ship tends to sink.
Interaction with Naval Tactics III: Stretch the Supply
The Smugglers of Port Royal sell Naval Tactics III: Stretch The Supply at Rep 3 for 500 Piastre. It adds +30% to Repair Kit duration. Combined with Epic Keelhold's +30%, the effective healing window grows substantially, which is the core of the late-game "impossible to sink" build.
Wharf Repairs (Non-Kit)
Between fights, parking at a Wharf allows the ship to repair using raw wood rather than kits. Wharf repairs are cost-efficient but unavailable during engagements and unavailable at sea. Plan to use Wharf repairs for out-of-combat hull resets and kits for in-combat recovery.
