I had never heard of a para-anchor[1] before, so I just looked it up - they're really cool! It's a brand of sea-anchor[2] that looks like a big parachute that goes underwater, effectively anchoring the boat where it is without having to reach the sea floor.

That makes me ill just thinking about it. We’re you always invincible to seasickness or was it something you developed?
