Floating Luxury Water Park

Seaworthy folding giant water park for cruise ships

When coming in to port folds up.

When out at sea and unfolded gives hours and square kilometers of fun, more than any land park could give. The slide down from the ship means extra fun.

The sharks across the glass floors are real life, adding a thrill you can never get from watching horror movies in a binge.

So this, but a lot bigger? https://www.superya...nflatable-sea-pool/

How much CAN you fit in a cruise ship cabin? https://www.youtube...watch?v=8ZvugebaT6Q

       That's so crazy it just might work! Not sure about square KILOmetres, but an inflatable (some air bladders for buoyancy, some water bladders for ballast) structure beside a cruise ship would allow space to escape the crampedness of cruise-ship-life. Slides, bouncy-castles, "beaches", inflated palm trees...

       Noice.   

       I like it, but it just wouldn't fold. Not the way you mean.

       A floating replica of Venice for those monster ships to dock with would be a winner. I once proposed a replica of the Galapagos Islands (will try to find)   

       I did a search and believe that Galapaghost, as I think it was called, got zapped along with about 30 other of my postings when the halfbakery went into a spasm a few years ago. I'll find it and repost. I have a print out.

       I posted two links which would make me call this idea baked, except that there is not enough description in this idea to know for sure.

       [xandram], I’m mostly you on this, I think it’s just a matter of scale. There are cruise ships with swimming pools, water slides, and other “water park” activities on board - and yachts with outboard swimming pools. I guess [pashute] wants to do the outboard thing in a very big way.

       i’m not fish boning I’m just saying it’s sort of baked. Except for maybe the * folding* , Which really has not been explained how it folds where it folds where it goes where it comes from etc. etc.
xandram, Sep 03 2021
  

       I suppose most of the support structures are inflatable, and when deflated rolled in / folded / collapsed by cables. Although that's gonna be a huge system (and a packaging problem) if the outboard portion is to cover any number of square kilometers.

       It's a pretty image. Folding glass floor is tricky.

       Let's say, hypothetically, you need 5 mm of solid surface over the entire structure. (Whether that's decking or "glass" panels". And another 5mm for a thin wall inflatable structure to provide buoyancy and support the decking. 1km^2 of park would then collapse down to 10,000 m^3 of volume. A standard cabin on a cruise ship is ~100m^3 (I think). So you'd be giving up 100 cabins for the park materials, out of about 1800 on a large cruise ship. And that assumes relatively straightforward requirements for maintenance, folding, crew, etc.   

       Not impossible, but I think you're likely to see much smaller initial sizes. Of course, the largest water parks in the world appear to only be about 1/4 km^2, so that's probably okay.   

       (ETA: There's 1 in China at 1.87 km^2, but all the others are significantly less than 1)

       [MechE], you're underestimating how much you can fit into a cruise ship cabin (link).

       I'm imagining an origami pop up book with pneumatic hinges and bladders. Bladders have internal shock cord tendons for folding up. Due to the size, a suction pump will be needed for packing away. The rigid origami panels could even be an internal skeleton inside the inflatables. Semi soft if you going to land on them though.

       The folded up gigantic contraption is towed behind the ship and left out at sea to be gathered again when the ship goes into the harbor.   

       Glass floor folds with Rubber/silicon frames and hinges allowing it to be folded in parts. It is held in place floating in water by thin floats all along, and wider floats on top so it stays verticle.   

       Then again, after watching [a1]'s "a night at the opera" link, maybe it would all fit into a cabin.

       And I'm thrilled to be talking again to MechE

       As a rule, unmanned, unpowered floating objects are frowned upon. You'd basically required a reserved mooring location at every port. Not impossible, but expensive. And my suspicion is that a continuous float design is more space economical than an intermittent one for a given displacement. But I haven't done the math on that.   

       A sunken design (that is, rigid walls and the horizontal surface below the water line, so basically a boat, or more likely a series of boats) would probably be the most space efficient, but it's not positively buoyant, which means that rogue waves or rain could sink the entire thing, which seems undesirable.
