Albert, who is just back from his round the world sailing trip asked me "What part of my boat has travelled the longest distance ?" Can anyone help him ?

who cares, but it is.....

Masthead, of course

the masthead has travelled ( 2 x pi x H) metres further than other parts of the boat which are H metres vertically lower down the boat, assuming er lots of things like the world being spherical, and so on.
 
Yes it is of course the ...

top of the mast.The earth is roundish and the top of the mast being the furthest away from the centre of the earth would form a concentric circle with the hull whose circumfrence would be bigger, therefore it would have travelled the furthest distance.

Re: Yes it is of course the ...

Again this is the simplistic answer, and not enough information is provided eg it might not have a mast or the mast might have fallen off and been replaced in Australia. Really, Badger, you ought to be a bit more careful in setting out the parameters!

I reckon the end of the boom (assuming sailing boat Jimi). Ok the top of the mast will have travelled further in the ratio Top of mast to centre of earth / centre of boat to centre of earth. However asssuming that he tacks now and again the meandering route of the boom will be surely longer?


Wont it????

Actually its the stern of the boat, cos he anchors up every night (from the bow) and the boat rotates around the anchot all night

If we're talking vectors, you're all wrong: if Albert's come back to where he started, he hasn't travelled at all. But then maybe that's the essence of what some people (not me) would regard as a pointless excercise. Did he have a good trip?

On the assumption that the boat is fitted with and sometimes uses an engine, how about the tips of the propeller? After all, they've been everywhere that the rest of the boat has been, but when the boat's under engine the propeller tips probably go nearly twice as far as the rest of the boat. Otherwise, how about the anemometer vanes or wind generator vanes?

That's actually a very good point cos the assumption TCM & Badger have made is that the distance travelled is relative to the centre of the earth. The answer would be different if it were relative to a fixed point in space.

Well if it was the top of the mast, it must have travelled further in the same time as the rest of the boat, and therefore faster. In which case, according to Einstein, assisted by Jimi, then surely the top of the mast when he got back would have been younger than the rest of the boat.
