"Rowing Eight Design From a Yacht Design Perspective"

Interesting article. Mark is a good designer - he draws fast, race
winning boats. Particularly interested in: "One is reducing the pitch
drag that arises from the rhythmic pitching of the boat through the
power delivery cycle of a single stroke. In particular the wave
pattern that develops at the stern of the hull suggests a hull shape
with a faster rise in immersed volume increase as pitch angle
increases might be able to damp the effect somewhat and thus reduce
drag."

I suppose that rather than narrow the stern to decrease volume, you
increase rocker, and bring the keel line up. So that the immersed
volume stays the same as it does at the moment, but increases sharply
as you increase pitch. You would have to manage the pressure release
carefully, though. But IANANA.

Unrelated question: do people put hull treatments on boats? McLube
hullkote/Holmenkol AquaSpeed or equivalent?

"British Rowing" Rule 2-3-8c. No boat shall make use of any substance
capable of modifying the natural properties of water to improve
performance
[I'm not confident that I understand what the words mean, and actually
I'd worry more about the crew's actions than the boat's, but the
intention seems clear?]
