The Limits of Bulbous Bows

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. 197-217, 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. 79-94, 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.
