The Seasteading Institute had some pages about concrete oceanic structures that captured my imagination a while back https://www.seasteading.org/2010/11/green-float-the-botanica... https://www.seasteading.org/2010/05/cocrete-structures/

They are not "boats" exactly!

Nice article, but note that the site's operator is "on pause in 2017", and the video appears to pre-date the damage sustained by the SS Palo Alto during winter storms of January, 2017.

For more concrete fun, and interesting material sciences challenges, see what floats civil engineering students' boats: http://www.asce.org/event/2017/concrete-canoe/

Slightly tangentially, there's a great short documentary on the building of Chevron's Ninian Central Platform at Loch Kishorn in 1978 [0]. At the time of construction it was the largest "man-made movable object". The base and supporting column for the drilling platform itself was constructed entirely out of concrete and floated to ~100 miles north east of the Shetlands.

Really is quite amazing that you can float a 600,000 tonne object several hundred miles out to sea.
