There's a long-lived niche interest in making yachts out of concrete and rebar.

It's not quite as stupid as it sounds. While it's not ideal for speedy sailing, it's cheap, exceptionally strong - which matters for adventures around ice - and low-maintenance.

But if it fails, it really fails, and the boat suddenly sinks like a rock.

Not everyone thinks it's a bad idea, but it's not exactly a mainstream hobby.
