>>> Portland Pudgy

Billed as the "World’s Best Dinghy", the Portland Pudgy certainly seems to be an interesting (and tough) design.

Made from rotation-molded polyethylene, it has closed-cell foam filling making it "unsinkable". Easily rightable (they have videos of it being done by a person in the water), it looks like a tough, serviceable boat.

How may dinghys have you seen flying?

A Portland Pudgy was used as a gondola under a bunch of helium filled balloons on an attempted Atlantic aerial crossing. Really.
