Some years ago we talked about using Basalt fibre as non-corrosive reinforcing. The technology is now available commercially from Texas and we can now look at relative prices and strengths.
See: http://www.sudaglass.com/index.html
Another technology that could be useful particularly for producing corrosion resistant impermeable surfaces is Solar Sinter. http://www.gizmag.com/solar-sinter-3d-printer/19046/
Its slow but its speed depends on the size of the Fresnel lens. At the equator there is ample sun. Materials that can be worked with include sand, seabed basalts and silica mud’s, possibly coral sands [calcium carbonates]. If the lens it self can traverse the surface of whole structures could be slowly sintered to seal it. Its early days for the technology and the work in gizmag is intentionally course for artistic reasons but it is a new resource that we could use.
For everyone’s information I was involved with the original Oceania Project in a small way. I’m also in several space organisations. And I have a Degree in sustainable Development, sustainable agriculture and renewable energy,water and sewerage.
Gizmag has a report on wave harvesting boats that charge on board energy systems. This idea is not new but it often gets forgotten.

Also should work for some energy consuming processes like fresh water production and electrolytic metal refining, aluminium etc. Since its likely to be crewed it counts as a boat stead but its most likely to be found in higher latitudes 30 to 60 where waves are strongest but not catastrophic.

Thanks for posting these links. Very interesting, especially the link to Sudaglass.
