Locked prop or not
Bein a physicist, I can sorta follow the various arguments on this but
bein an engineer (a physicist/engineer is a serious contradiction) I know many of you are askin the wrong question. In some cases, Yanmar for example, it has nothing to do withj drag and a lot to do with lubricating the tranny. I saw in print, years ago, that they actually reccomend putting it in reverse. I always forget to do this and have never done it in years of sailing and my engine/tranny is 20 yrs old. |

Why not simply try it. Go sailing and have your knotmeter working (mine doesnt work) with prop locked, record speed, unlock it and go for a minute and record speed. Do this maybe 10 times and average. Tell us what happens. Theory and talk is great but reality makes the world work. |

As said in another thread about this, we have tried it, but without conclusive results. Many factors influence the speed o a sailboat, and the instruments are not that accurate ... but the thread gave other ideas for testing. -- Flemming Torp |
