Is this about the bow or the bridge? This[1] looks like a hemispherical bow to me. The article talks about wind tunnel tests, making me think they're not talking about under-water features. Are air-based tests valid for fluids with such drastically different density and viscosity (e.g. salt water)?

Edited to add: it seems that the "bow" is "the front of the ship"[2] and not specifically any part above or below the water. Looks like in this particular design, the bridge is at the bow, and the bow is round. [2] - https://en.wikipedia.org/wiki/Bow_%28ship%29 https://en.wikipedia.org/wiki/Bow_%28ship%29
