Of course it's a light spell, what else could it be?
It's interesting to see what individual settings will and will not call magic. The word itself has a very flexible sort of definition, even within one self-contained work. And it gets doubly weird when crossing over works in fan made stories, trying to see what meshes and what doesn't. I personally am not a fan of some tabletop RPG magic systems because, well, they're waaaaay too complex for me. But I can acknowledge their flexibility.
One of my favorite parts of Pathfinder, unlimited 0-level spells. Dancing lights wherever you go! Free +1 bonuses for everything with guidance! Makeshift field refrigeration with ray of frost!
I don’t know if the smell of freezerburn is much better, personally. Better undoubtedly, but MUCH better? I guess depends on how much that boat would have decayed, and just how smelly it was to begin with.
"It's just one light spell."
Isn't it almost required that a statement like that be followed with, "What could possibly go wrong?"
