🌊 Quad's Jet Skis

A jet ski for Valheim: a fast little boat for one (and a friend), pushed along by a surtling core's fire instead of the wind.

✨ Features

Riding it

• Build it with the hammer on the water, near a workbench, like the raft: 12 Fine Wood, 30 Bronze Nails, 2 Surtling Cores and 4 Deer Hide.
• Press E on its handlebars from the water or the shore and you climb onto the saddle and take them.
• Hold W to go, Shift+W for full speed, S to back up; let go and it coasts to a stop. The wind doesn't matter.
• A and D steer: the handlebars turn and come back to the middle by themselves. It turns slower when barely moving, and stays level in a hard turn.
• Jump to get off.
• Leave it at the shore: with nobody aboard it stays where you left it, and the waves don't wear it down.
• You ride it like a jet ski: leaning over the bars, hands on the grips, feet on the pads, your head turning where you steer, bobbing over the waves. Everyone sees it.
• A gauge at the bottom right shows your speed and throttle, in place of the boat's wheel in the middle of the screen.
• Running into a friend at speed doesn't hurt them, and hopping waves barely scratches the hull.

Room for two, and their things

• A passenger seat behind the rider (E on the back of the saddle): the passenger holds on round the rider's waist.
• Saddlebags on the back corners hold 8 stacks: E on them, or Tab while riding. If the jet ski breaks, what's in them floats away in a cargo crate, as from a Karve.

The look and the sound

• A dark wooden hull with a band of red-stained wood and bronze rivets, a rub rail, a round shield on each side, a curled prow like a longship's, a leather saddle, a cowl up to iron handlebars, and a surtling core in an iron cage feeding the jet nozzle.
• Paint it: E on the cowl in front of the handlebars gives the next colour (red, blue, green, teal, purple, black, bare wood). Everyone sees it.
• An engine that burbles at idle and screams at full speed, spray thrown up behind it and off the side in hard turns, and a core that glows brighter (and lights the water further) as you open the throttle.
• It is the game's raft underneath, so it floats, wears, breaks, saves and changes hands in multiplayer as the game's boats do.

Everyone in the world needs it installed.

Full speed along the shore: hands on the grips, spray off the nozzle

From the side at dusk: the painted band's bronze rivets, a round shield, the saddle and the caged surtling core

From behind: the core glowing in its cage and the jet's spray on the water

Stopped on a misty morning: the curled prow, the painted cowl and the iron handlebars

📜 Recent changes

• 0.3.0 In your language: Russian, German, Chinese, Portuguese, Spanish, French, Polish and Turkish (translated by AI; corrections welcome). A jet ski left alone stays where you left it: it no longer drifts ashore on the waves, and knocks against the beach no longer wear it down (jet skis left near the shore broke after a while). A crash while you ride still hurts it.
• 0.2.2 Spray you can see: a rooster tail of water arcing out of the nozzle that grows with your speed, a curl off each side of the bow, a sheet thrown off the outside of a hard turn, and a trail of foam left on the water behind you. It's made of the game's own splash, white mist and droplets (the old spray was flat patches of foam that didn't show in the air).
• 0.2.1 The passenger hugs the rider on every player's screen: each game now knows for sure who sits behind whom (it went by where their body was, which arrives late from another player's game), and puts other players exactly on their seats, so nobody trails behind a jet ski at speed. Both of you need 0.2.1.

Every change is on the Changelog tab.

0.3.1

• On a server without Jet Skis, the jet ski is gone from the hammer, and a message says why: the server would delete a jet ski built there, with whatever was in its saddlebags. Server owners can change what a jet ski costs ("3 - Building", Cost); in multiplayer the server's cost applies, and a cost with a mistake in it keeps the last good one. Settings: edits to the config file now apply while the game runs (a server owner no longer has to restart), and a server's admins can change the server's settings from their own game with Configuration Manager, where other players see them greyed out. Your config file always keeps your own values while you play on a server (saving it there could write the server's in). Players on an older version still get the server's settings.

0.2.0

• You ride it like a jet ski now: leaning over the bars with your hands on the grips and feet on the pads, your head turning where you steer and bobbing over the waves (everyone sees it). A passenger seat behind, the passenger hugging the rider. Saddlebags (8 slots, a cargo crate if it breaks): E on them, or Tab while riding. Paint it with E on the cowl (red, blue, green, teal, purple, black, bare wood). An engine sound, spray off the nozzle and in hard turns, and a core that glows brighter with the throttle. A gauge at the bottom right (speed, throttle) in place of the boat's wheel. It sits right in the water (it rode too low), and stays level in hard turns. Shift+E is left to other mods (Wayfinder names boats with it). Restart the game to see the new parts on jet skis already built.

0.1.0

• First release: a jet ski built with the hammer on the water. Hold W to go (Shift for full speed, S to back up), A and D steer and it leans into turns, E climbs on from the water, Jump gets off. A surtling core pushes it, not the wind. Its look is built in the game: a red-banded wooden hull with bronze rivets, shields and a curled prow, a leather saddle, iron handlebars and a caged, glowing core.
