Papers

The "Push-Me Pull-You" Boat is Better Still (PDF)
Ruina, A., 1978 (in revision for American Journal of Physics).

My first paper, on sailing upwind and sailing downwind faster than the wind, is in its nth year of revision (subtract 1978 from current date to calculate n) .
For related you-tube videos, search for DDWFTTW, DWFTTW, Direct down wind faster than the wind, or down wind faster than the wind.
