    Cool. Does it increase resistance and reduce efficiency, thereby requiring more fuel to be burned? Or, like the dimples on a golf ball, does the surfacing make it go better?

    There are two kinds of boaters: those who have run aground, and those who lie about it.

    3M riblet film reduced drag when applied to the aft half of a boat (Stars and Stripes used it). Same principal as the golf ball dimples. Riblet film increased drag when applied on the front half of the boat. I can't remember if covering the whole boat was a wash or just less effective at reducing drag. <<EDIT. This ain't google expertise. I have talked to 3M and a hydrodynamicist at MIT about this for a similar application.>>

    This sounds somewhat similar, but i can't say it isn't snake oil. https://www.kisspolymers.com (science link)

    I wondered the same thing. The writer didn’t specify. I’d guess that any increased shear compared to slick hull would be outweighed by the average efficiency over the same hull as it was covered in barnacles, along with saving the cost of a haulout and barnacle removal.
