Titanium in Yacht construction?

I have heard of a yacht hull made of titanium, located in Russia.

Japanese fisherman have made a nice titanium fishing boat

To put this in perspective, for all of you golfers out there, look at the costs of a Big Bertha driver, then imagine the metal necessary to fabricate an entire yacht.

I am aware of a Sailing yacht that was built out of Monel, the builder was involved in the construction of a refineary here in the mid east so had access to some free 'off-cuts'.
A friend caught sight of her a few years after she was launched, pristine unpainted hull.

New study re: Titanium for marine construction

This just was published... makes for an interesting read.

U.S. Navy: The Business Case for a Titanium

It looks like it might be suitable for a unique yacht, certainly the weight benefits could help the "big and fast" tradespace, and the corrosion resistance is a big plus. What do the Naval Architects in this crowd think?

My company has been fabricating various underwater appendages in titanium for almost 10 years now. It is lovely 'stuff' to design and build with and is completely unaffected by corrosion.

But the material expense is, as everyone knows, incredibly high. IMO..the only rational way to justify a titanium hull is based on total cost of ownership over a very long planned life expectancy. (Or some fairly extreme performance objective(s))

Although...and as noted in the USN studies..the recovery of $$ in the scrap process is significant.
