I came across this section of video discussing how the bulbous bow increased the speeds attainable by Yamato.

Question: Is it possible to estimate how much (if at all) a bulbous-shaped bow would have increased top-speed on the Iowas?

I've seen various rumors that the Iowas were able to exceed their stated top-speed of 33 knots (35-37). Could such a bow have made it possible for them to hit 40+ knots?

Are their any back-of-the-napkin sorts of engineering calculations for drag-reduction that would make it possible to compute a rough estimate of the effect a bulbous bow on their designed speed?

Thanks.
