Photographic Record of Construction

 
 

A picture tells a thousand words - so here is the equivalent of many thousands of words and a lot of effort.  As of April 2015, the construction is substantially finished.  The pictures still seemingly show Etna as unfinished; however, most subassemblies - boiler and pipework, engine and drive train, flooring, aft cockpit and bow cockpit - have been assembled, tried for fit and removed for varnishing or painting.  The underwater surface of the hull now have antifouling:  all through hull connectors are sealed ready for trim tests once all heavy items are (re-)installed.  The roof is complete and has been mounted.


I am now catching up with technical documentation.  Click on the links below for technical and system drawings.
