Sea Route

Chart voyages across the Great Ocean and let an automated helmsman navigate your longships and karves. Sea Route provides a full in-game Norse navigational dashboard, real-time map pin projection, 12 ordered waypoint slots per route, 1-click waypoint jumping, interactive cartography picking, and hydrodynamic anti-capsize stabilization.

A Valheim BepInEx 5 plugin.

What's New in v1.1.0

Norse Obsidian & Antique Gold Dashboard: The route list is the Sea Route tab on the DFG board. Press E on a chart table, or Alt+T and choose that tab.
Multi-Route Library: Save, name, cycle, and manage multiple distinct trade routes and expedition channels.
12 Waypoint Slots per Route: Supports Start Pin, Pin 1 through Pin 10, and End Pin.
Dynamic Cartography Projection: Whichever route is active automatically displays its waypoints as custom ship pins on your world map (M) and minimap in real time.
Interactive Map Picking: Click Pick Map or any slot's Map button, then simply click anywhere on the cartography map to drop coordinates directly into that waypoint slot.
1-Click Destination Jump: Click any pin's name, coordinates, or badge in the dashboard to immediately steer the ship towards that stop as its next destination.
Seated Start / Stop Hotkey (Alt+G): Engage or halt autopilot with a single keystroke while seated on boat benches or clinging to the mast without standing up or grabbing the mouse.
Hydrodynamic Anti-Capsize System: Preserves full ocean roll damping and applies active righting stabilization so smaller vessels (like the Karve) will never flip upside-down in swells and storms.
Seated Ejection Protection: Clicking inside the menu or placing map pins will never trigger attack swings or unseat seated vikings.

Features

In-Game Navigational Dashboard (DFG board, Sea Route tab): Live speedometer, gear indicators, active target distance readout, route management, and waypoint controls.
Autopilot Navigation: Drives the ship's rudder and forward momentum between ordered waypoints (Start ➔ 1-10 ➔ End), slowing down to an arrival stop at your final harbor.
Speed Gears: Three distinct static gears (Cruise, Standard, and Full) toggled with Alt+J or 1-click dashboard buttons.
Shallow-Water Safety Probe: Automatically scans the seabed ahead of your keel and holds position if reefs or shorelines threaten grounding.
Chart Table: Placeable Norse cartography station (Hammer > Misc, unlock via Alt+B) for dockside voyage planning.
Web Navigation Deck: Optional live route manager served on localhost (http://127.0.0.1:8778/).
