There are plenty of things in the water capable of pulling a boat. But not many that would take a small lure.
I once got hooked up to a manta ray that snapped my 30lb line like cotton. It was foul hooked and I watched the whole thing. It was crystal clear water at Shellharbour boat harbour. I had just cast and I was watching the bait sink when the ray came along and ran straight into my bait. It was hooked on the wing and it just kept going.
