also affects the player when a passenger is in the boat

Personally I do not think this is worth fixing.
Nearly every mob has different leg length or no legs at all. Implementing for every single mob a special case is in my opinion not worth it and not even possible.
For Endermen it looks already strange because they are kind of floating...

Creeper is still not fixed.
Players can attack Creeper from boat bottom.

Since villagers are completely anthropomorphic, shouldn't the fact that they don't adopt a sitting position like other mobs do be considered a bug in its own right?

Please link this in the description of the report.
The following is based on a decompiled version of Minecraft 1.12 using MCP 940
The reasons for this is caused in the method net.minecraft.entity.item.EntityBoat.updatePassenger where the setposition for passengers is set, at first the posY float looks to not cause it.
float f1 = (float)((this.isDead ? 0.009999999776482582D : this.getMountedYOffset()) + passenger.getYOffset());But once you go to the method getMountedYOffset() you can see why this happens,
public double getMountedYOffset()
{
return -0.1D;
}what this does is return the value '-0.1D' which will set the entity 0.1 down therefore the entity goes through the boat.
Potential fix
Change the value to '0.0D' so it will return the value 0, which basicially means it will not change it's posY.
public double getMountedYOffset()
{
return 0.0D;
}I'll attach two screenshots with the potential fix.
Hope this helps and explains this issue 🙂
