Several Minecraft mods enable the creation of multi-block ships. The
most common crafting recipe shared among them for a “steering wheel” or
“helm” node (they use different names for the equivalent of the meshnode
controller) is the following:
wooden plank, stick, wooden plank
stick, iron ingot, stick
wooden plank, stick, wooden plank
A good example would be Archimedes' Ships Mod:

I disabled some mods and a ship produces crash with error

So this is a quick fix to get the world working again
