Yes, reefs use the similar stuff but how do you get that to bond together in a useful form; and yes it blooms naturally in the ocean but I have never hears anyone say “I have to scrape this layer of coccolithophores off my ship”.

But you’ve probably herd of people scraping coral off their boats.
Harry Pidgeon mentioned it in his book,
he was the first seasteader,
to sail around the world,
single handed.
He made his own boat out of wood,
it was called the Islander,
and lived the rest of his life on it,
though did eventually construct a second boat.

Actually it is believed they used Geopolymers.

But this does seem like a good posibility for construction of seasteads.

Self-healing concrete boats be appealing.
