Seems the front section has broken as it rises and falls separately in the swell.
it will cost a lot to raise and destroy her, who pays? Just out of curiosity.
Even ferro yachts in good condition have a hard time obtaining insurance cover - aided no doubt by the many 'amateur' built vessels that helped to give them a bad reputation.
Ferro advocates preach about how strong they are - yes, cement is very strong in compression, but very weak in tension, unless it has steel added - and even then there are all the areas of cement between the bits of steel in the structure that are thus weaker.
About 20 years ago a 38' ferro yacht (built to a high standard) washed ashore here in the aftermath of a hurricane that passed nearby - she came ashore on a gently sloping sandy beach. In spite of this, there were many cracks sustained in the hull, and she was broken up by a JCB and taken away in skips.
A 37' single chine plywood yacht (fin keel and spade rudder) also came ashore on the same beach at the same time - her rudder broke off, and she sustained one small hole punctured in the hull, but she was recovered and quickly repaired, and was sailing again soon after.
Some friends sailed out here from England on their 40' ferro junk schooner 'El Lobo' about 15 years ago - from here they sailed to Tobago, where an errant jet ski had an altercation with them, tee-boning the hull amidships. And the bow of the fibreglass jet ski punched a hole in the hull (between bits of steel), thankfully above the waterline.
One positive aspect of ferro construction (one of the few) is that small holes like this are easily repaired.
John Rodriguez has now sold this ferro schooner twice - I remember the asking price the first time around being in the high two hundreds, and then it gradually reduced - second time around and the new owners had spent a fortune on re-fitting her, and then her new asking price was GBP 175k, and the odds are that she sold for a fair bit less.

Moral of the story - be very wary of ferro yachts, even in good condition like Wild Knight, and stay well clear of 'ferro fixer uppers'!
If all the promises about graphene come true we'll soon be eating space food and living on Mars. See also: buckyballs.If the promised advent of low cost flash graphene as a structural additive to concrete comes to fruition, perhaps we'll see the re-birth of cement boats.

I suspect they might be more interested in the production of hemp fibre. Graphene is certainly causing some excitement in the construction industry as a cement additive, if only the volumes were available.Is it suitable for bearded 1970's hippies to make a blue-water cruiser in a farmer's field?

Paint? Works for steel boats, which are also electrically conductive.Except graphene concrete is electrically conductive so the boat’s steel structure will be slowly fizzing away on top of all the other problems!
There are solutions but the price would probably be prohibitive.

I think your last point - emboldened - identifies the problem. Ferrocement was seen as cheap and cheerful, and while that might have been the case for hulls, the hull is only a small part of the cost of a finished boat. A lot of people looked at the materials prices, thought "Wahay", slapped together a 40 or 50 foot hull ... and then discovered how much a single sheet winch for that size of boat costs.True, but really needs to be epoxy based to be durable which equals controlled application + maintenance + money and all that jazz. Then there’s the isolation etc on what is supposed to be a cheap n cheerful DIY home-build solution?
