Bulbous bows are not miracle devices. Learn their limits and how to use them effectively.

Want to design a bulbous bow? Start with these two papers:
A. M. Kracht, "Design of Bulbous Bows," SNAME Transactions, vol. 86, pp. 197217, 1978.

P. Blume and A. M. Kracht, "Prediction of the Behavior and Propulsive Performance of Ships with Bulbous Bow in Waves," SNAME Transactions, vol. 93, pp. 7994, 1985.

And just to prove that there are exceptions to every rule, meet a firm that developed a simple bulbous bow. It looks like a dumb pipe, but they have model tests to show that it works.
