I am under the impression that most boats are tsunami-prof as long as they are out at sea since, at sea, tsunamis basically just manifest themselves as very large swells. This looks pretty neat though regardless. Wooden boat building is very cool.

  Tsunamis are not killer waves or rogue waves, they're strong displacements of water. The height happens only at the shore because the sea floor rises up to meet the shore. At sea, one probably doesn't even see anything abnormal as the wave ( more accurately, the pressure crest ) rushes past underwater.

From the "What is it?" page: "After the Japanese tsunami in March of 2010 I started to wonder how a family might survive such a brutal and sudden event. The project started as a series of creative conversations and sketches with friends about possible ways to escape a tsunami with your family in tact." I'm taking this to be for a family that isn't already at sea but can, on short notice, crawl into the emergency floating-ball escape pod for safety.

  Ah, that makes more sense. I'm not sure how well it will work, being made of wood and considering how violent and chaotic tsunamis are once they hit land, but I suppose it must be better than nothing.

    That's what I was thinking. The problem on or near land wouldn't be staying afloat (which I assume a ball like structure would manage) but surviving crashing into structures and other floating debris. Wood seems to be a less than ideal choice for that. Perhaps a metal ball would dent but not break/leak like I'd expect wood to. But it looks like the maker has given this thing a lot of thought, so there's probably something I am missing.

If you are near land then he will have the same problem as hurricanes. It is not that the wind blows Xmph during a hurricane, it is WHAT the wind blows Xmph during a hurricane.
- jlgreco 13y ago
  Yeah. Perhaps that could be mitigated by storing the boat somewhere that you would otherwise escape to such that the boat is a contingency plan for your contingency plan. So like, stash it on your roof (where you would normally flee if you had mere minutes of warning). If your house starts to collapse, at the least you would then have a chance.

Perhaps you want a tsunamni-proof boat that you can keep behind your house, on dry land, for emergencies?

It depends how far away from land you are. A Tsunami has tons of energy, but it only really gets 'big' on the surface when that energy is constrained by the depth of the sea floor. That's why if you're on a boat and get a tsunami warning, it's better to head out to sea.

Yes, if you see it coming and take it head-on, you'll be most likely fine: http://www.youtube.com/watch?v=OdhfV-8dbCE http://www.youtube.com/watch?v=OdhfV-8dbCE A tsunami at sea is fairly harmless compared to rough weather: http://www.youtube.com/watch?v=mPBaqh3dcVM http://www.youtube.com/watch?v=mPBaqh3dcVM However, upon hitting land, the wave gets shorter and taller: http://en.wikipedia.org/wiki/File:Propagation_du_tsunami_en_profondeur_variable.gif http://en.wikipedia.org/wiki/File:Propagation_du_tsunami_en_...
