Raglan Surf Report is back with another lesson in surf etiquette. This time it’s a tutorial on not ditching your board at people while they’re enjoying a nice tube ride. It’s also a helpful explainer on the dangerous pointy bits of a surfboard—the parts to avoid.

The video ends by advancing the controversial position that soft-tops are the only acceptable boards when it comes to accidental, or purposeful spearings. Watch and learn (and laugh).
