Here's another one. This is a modern racing DN with a Carbon Fibre mast. The mast bending is not an exaggeration. The first DNs had laminated two piece Sitka Spruce masts. Some were even hollow. They would bend a little. Then some people went to aluminum masts if they just wanted to sail around. Carbon Fibre is now pretty much required if you are serious about racing.

The bendy mast is designed to absorb the wind gusts so the boat doesn't pop up ..or "Hike". Hiking is considered in-efficient, in that the wind power is "wasted" in lifting the boat off the ice, rather than driving it forward. With a bendy mast and runner plank, ..All the winds power is directed toward driving the boat forward.

EDIT: I think I should Note...The Audio in the tape is not faulty. The noise you hear is the Real Sound of the runners Clattering over the ice.
