Know him? No, he’s not sent me photos. But I just learned his name, and I’ll introduce you to him after a few photos that I’ve taken.
What surprised me about the photo above and below is that two sets of markings exist.
Here’s the more standard quantification system.
The difference between the waves produced by the ship and the tug appear to be explained by structure below the waterline.
The next two photos were taken in freshwater where water clarity is substantially better than in the photos above.
So back to Mr Taylor. He was a naval architect and engineer working for the US Navy and credited as the creator of an experimental model tank used in navy ship design. According to this paper, the David Taylor Model Basin is where the bulbous bow was invented.
All photos by Will Van Dorp, who hopes some of you with naval architecture training respond to this.

Will – Thanks for posting the link to the bulbous bow paper in the blog, it was great. I’ve been interested in that kind of thing ever since first reading how Vladimir Yourkevitch revolutionized the shipping world with his bulbous bow and streamlined hull on the NORMANDE, which changed the course of design history for every large ship hull built after her. If anyone interested in hull design reads this and hasn’t yet clicked on Will’s link to the paper, I suggest you go and take a look; you won’t be disappointed! Thanks again, Will – Jim Gallant.

The more fair a wave-breaker bow is the more pronounced its affects. Some studies (Stevens Tech, USN Chrystal City, and David Taylor Tank Testing)indicate a 12 to 15 percent improvement of productivity at a cost 42 percent lower than a conventional bow.
