Hi all,

Perhaps the answer is never or only when the ship sinks, or during some major weather event, because, the tide only ever rises for six hours, so, whether the boat is anchored or not, the water will never reach the third down under normal circumstances.

Whether or not the boat rises, since there are 2 high tides and two low tides per 24 hours, the time between low tide and high tide is never more than 6 hours, give or take. Since to reach the 3rd highest rung would take over 8 hours, it could not possibly reach it at the rate described.

I was also tricked into doing the unnecessary math, but still got a different number than all y'all. One guy posted the following:

180 --- 10
160 --- 9
140 --- 8
120 --- 7
100 --- 6
80 --- 5
60 --- 4
40 --- 3
20 --- 2
0 --- 1

So the third tave from the top (#8) is at a height of 140cm divided by 15 mins per hour leaves an answer of 9hrs 20 mins. Of course, we all know the tide would already be going down again and the boat wouldn't sink...but just testing the math part...

Fooled me too! But since I did the math (assuming the ship doesn't move) I also got 9:20

I think you guys are missing the point. The third stave from the top is NOT # 8, it's #7. If #10 is the top, then it follows that # 9 is the first from the top, #8 the second, and 7 the third.

It's the same as a race. There's a winner and then there are runner-ups. The first runner-up is not the winner (top stave), it is the one that directly follows.

If that's the case, the correct math answer would be 8 hrs [120cm/(15cm/hr)].

It's all irrelavent, I concede, considering the correct math answer is not feasible anyway.

I think that saying #8 is third from the top is true. We're saying it's the 3rd rung from the top, not the 3rd rung from the top rung. Likewise, #3 would be the 3rd from the ground, but only the 2nd from the bottom rung, even though we agree it doesn't matter in this puzzle.

Call me goofy fellas, but if the ship is floating, hence being anchored to prevent it from drifting away, then the rising tide will also raise the ship the same amount as the rising of the tide in terms of distance from the sea bottom.

The bottom tave will always be in the same position unless the ship sinks or increases/decreases its draft due to cargo operations or ballasting/deballasting.

As for the anchor holding a ship to the bottom if it were to come to a short stay; the bouyancy of the vessel is sufficient to carry the anchor as part of its compliment. How on Earth is it going to hold it to the bottom?

Common sense prevails at every turn. Congrats to those who posted accordingly.
