![]() Same as a sailboat. Can go much faster than the wind. Actually, sailing is different because of the interaction of the keel and the water. You can't go faster than hull speed, but ignoring that you could theoretically go faster than the wind, if you were going at 90 degrees to it. You can even sail INTO the wind. You can't, however, run before the wind faster than the wind (unless you have one humongus current) Jose -- (for Email, make the obvious changes in my address) |

The ability to do so depends on the relative forces between the water and the second medium. Sand and Ice yachts can readily demonstrate a course speed downwind faster that the wind. In effect they are tacking downwind. If you are being very precise then you cannot run before the wind faster than the wind because running before the wind depends only on drag and not on lift. -- David CL Francis |

![]() Sand and Ice yachts can readily demonstrate a course speed downwind faster that the wind. Straight downwind? So they would be overtaking the wind? Howdeydodat? In effect they are tacking downwind. Oh, then they are not "running" before the wind, they are sidestepping to some degree. Jose -- (for Email, make the obvious changes in my address) |
