The article mentions Sydney harbours 18 foot racing skiffs. These are very light 3 man racing vessels with far more sail than boat. They are very fast and require all 3 crew to be suspended on trapeze wires far from the hull, just to stay upright.

They are fun to watch because they flip and capsize a lot.
