Boat Speed

Does anyone know how fast rafts and sailboats are exactly?

Looks like a complex answer, this is the code responsible, but it varies based on a lot of things and I'm not finding a single max speed written in stone. You'd have to trace out how high the math goes to figure out the max speed.

I also can't find any multipliers for boat type. I believe this code handles both sailboats and rafts, but the only modifiers I see for speed are the status of the sail and how many people are rowing.

I see, looks like I'll just have to get a stopwatch and measure it the old fashioned way.

I've done some testing, seems like rafts are roughly 200 blocks per minute, while sailboats are about 400 blocks per minute.

I would've thought atleast the sailboat would've been faster than sprinting, but I guess not

The boat speed multiplier is in boat.json.

FYI to anyone trying to find a way to change boat and raft speed in singleplayer without using a mod:

I edited "boat.json" found within C:\Users\[YOURUSERNAME]\AppData\Roaming\Vintagestory\assets\survival\entities\water and changed

speedMultiplierByType: {
"boat-raft-*": 1.0,
"boat-sailed-*": 1.2

TO:

speedMultiplierByType: {
"boat-raft-*": 1.3,
"boat-sailed-*": 1.6

This gave me a noticeable speed boost without seeming to change turn speed or feeling completely ridiculous or OP. I have not unlocked the elk and cannot confirm if it works with these changes. Do so at your own risk.

I also use the Rivers mod and changed river speed to either 2.0 or 1.5 which lets me go upriver using both a raft and a boat. It is slow but I felt it was balanced enough for a improvised solution such as this.

I host a private ad hoc server for a handful of other players and it worked in this case.

This was on version 1.20.4

You're right, it is not an absolute speed as asked by the OP, but it is the closest we have when added into your code section.

One thing that I've noticed is that two things really slow me down:

• Looking to the side
  (I REALLY wish this was not the case. You don't slow down in a real boat or raft if you look to the side.)
• Tight or frequent turns.

Dang, missed that and that was the first place I looked. Appreciate the second set of eyes!
