Hehe, yes, it's a bridge. It's the right picture. And I'm not pulling your legs. That is a concrete bridge immersed in seawater. If they can pour that thing from concrete, surely one can build a good pontoon from concrete.

Well, that was my reasoning, anyways.

you mean a floating concrete bridge on sea water? Great Scot.!!!

LOL, no - I'm saying that if they can build that thing, you can certainly pour concrete well enough to make it strong enough to support your floating home.
Of course one of the biggest bridges in the world doesn't float, but if concrete is stable enough for that application, it will be stable enough to make a couple of pontoons. Just take adequate care while pouring it.

Edit:

To prove my point, this company make concrete pontoons for marinas/harbours:

Floating concrete bridges in salt water are not common but they do exist. http://www.kiewit.com/project/pro_29003001.html Sorry for the sidetrack, but this shows the usefulness of concrete floats.

Heh, nice

A little low in comparison to the bridge of Storebælt, but cool example, nonetheless

Just a idea . lots of cape island lobster boats around here . fiberglass over wood goes real cheap . build a longer house on it . Ive seen a few done that turn out good .

And if you ever did decide to cross a ocean you probly could . I Lobster fish in a 38 foot cape islander now . we've hauled in some severe conditions (gale force), they can take some sea .
I think I even know some solid fiberglass ones that are going cheap . A fellow here with a 42 footer just ordered a new boat . his old one is well kept . might not be as pretty as yatchts but will do the trick .
