Maybe one should not go sailing if you can't deal with the issues that come up, short of being run over by a tanker or something? Sounds pretty simple. Can you deal with a tsunami arrives with no warning and kills some 5,000 people in your immediate area? A 60 MPH squall that hits you at night? Of course not. A couple of things occur to me. First, I thought a tsunami was only dangerous near land. If that's the case, then how could it do damage to a boat that's sailing offshore? Second, it seems like you should be able to handle high winds. Wouldn't you be prepared for that? Why are you sleeping when there's a storm going on? snipped. A tsunami, or any other wave is simply water in motion. Depending on the length and speed of the wave, the amount of vertical movement is generally dependant on the depth of the water it is moving in. So you are correct to say that in deep water they don't have much height, but simply saying "off shore" isn't a sufficient description as you can be quite a distance "off shore" and still have relatively shallow water. in among the S.W. Thai waters, where the Tsunami did the most damage, waters are generally less then 100 ft. A "Sumatra", which might be called a line squall in other parts of the world, is a rather brisk wind that travels fairly rapidly and if at night generally is bit of a shock. In the case I mentioned I was sailing north along the E. Coast of Malaysia on a fine moonlit night with about 5 K. wind. Then, within only a few minutes it was blowing 60 miles an hour for about an hour. As in the case of the Tsunami, it has been stated that it is the worst natural disaster in Thai history. A bit hard to plan for. Squalls occur, frequently with no warning, certainly not something you can specifically prepare for other then in a general way that you know it might blow a bit. And I don't remember saying I was asleep when the squall hit. Cheers, Bruce |
