Suspect you're right. Makes it easier without tapers to make the mould, but more windage when reefed

Not sure what you mean but if it reduces those loads and controls shape it makes it interesting

This appears to require either a large diameter lower bearing or a bent section. Both of which can make life difficult with the engineering. not sure how it would scale up

Good news. Still don't see why stainless rather than carbon
