What is Reddit's opinion of Principles of Yacht Design?

From 3.5 billion Reddit comments

Wetted area is a significant concern in hill design. Wetted area increases drag, but waterline increases top speed. Further, bouancy and righting moment are strongly affected by hull shape at various angles of heel.

All of these issues are competing with one another when designing a hull. Increasing waterline allows higher top speed (based on the bow to stern standing waves), but increases drag in the water (needing more sail power for the same speed).

A narrower hull will have less wetted area and less drag, but will also have less stability, and be more difficult to right itself from high heel angles. This could be offset with a heavier keel, but that's more weight and so you need more sail... which means you have more force pushing you over!

I found Principles of Yacht Design to be accessible, albeit highly technical, introduction. But I am a trained engineer in other contexts, so that probably helped... https://www.amazon.com/dp/B00H878Q54/ref=dbs_p_ebk_dam
