hi what is average hull thickness of 45ft yacht.

Well, Pascal, the spanish even managed to design a navy submarine that would not surface (too heavy to float) because someone messed up a comma...
So let´s not waste our time discussing that minor difference of building 3 times longer than initially mentioned...

I would suggest starting at 45 inches.

Good suggestion. With that size he might also get away with somewhat lower hull thickness.

Not a chance. This is far too entertaining!

Hope you're ready to cover his yacht when it's finished. He's a genius so it will be worth headlines. Maybe he'll give you a projected date.

You are an evil wicked man....

Think I'll build a boat tomorrow. Maybe out of sand.

Silly woman.

Your castle, not your boat, is built out of sand.

Ships built of sand

There where a lot of ships, boats and even yachts built of sand. With a little addition of cement of course. Building vessels out of concrete was very common, when steel was a critical resource and it was a very cheap method of building ships.

The material is called Ferrocement. Quite a few home built yachts (sailing and power) where launched, using this building technique.

And there are even more uses:

Rogers Group, Inc. | Crushed Stone | Sand & Gravel | Asphalt Paving | Road Construction > Industry Resources > Rockology 101: Learning > Sand, It's Not Just For Beaches

P.S.- Addition of cement is cheating.

Then we are back to the roots .

...seems like that´s exactly what this thread is about. Now we´re right where this was meant to go.

You guys chased the GENIUS away!
We could have found out a lot more about P_Bear by now, for example, is he a 15 y.o stirring us all up or a wealthy inventor trying to make friends around the web
I once had a client who was a genuine genius in the computer game world and although he was eccentric in many ways and wanted unique inclusions in his home that I had never done before, he was also one of the most modest, generous and polite persons I have met. There was also a great language divide between us as he was Japanese, this made little difference. Within a few meetings he proved to have learnt as much about the engineering required for his home than the engineer we had employed.
As one member said, if you are a genius, it will show quick enough, no need to sprout about it. He still remains one of the best clients I have worked with.
I doubt very much this P_Bear was more than a bored kid.

maybe he decided we´re not worth his brilliance and so he went on to enlighten our friends at BD.net instead...

"you piss yourself up" - I'm still curious about this. I hope he returns.

Between that and suing us all. Not real sure what he thought he could sue us over though.

SolarSinter : markus kayser I'm going to 1up you by 3D printing a yacht out of sand!

Perhaps find out the weight of the bare hull for the boat you require and extrapolating from there might be a good cheat method of working this out?

Who has a glass bottom boat? Guessing we'd need a minimum of 3/4" of thickness, so it'll be easy to see the S.S. Genius on the bottom after its maiden voyage
