Physicists claim new insight into wake behavior

In the 1880s, the great British physicist Lord Kelvin argued that the wake of a boat fans out at the same angle regardless of how fast the boat is going, but scientists and engineers have long known that boats sometimes appear to have narrower wakes.

Now two French physicists say they've explained that narrowing.

Their idea might not sail smoothly into the textbooks, however, as experts in marine engineering are skeptical.
