The Captain’s Journal

BACKGROUND READING

Research sources

Public originals for references in our ferrocement, rigging and marine electrical research library.

The journal tells our family’s refit story. These references provide related technical background; their inclusion does not establish that they were used for every past decision described in the story.

They are not vessel-specific design approval, as-built specifications or instructions to carry out safety-critical work. Suitability for Tortuga requires current manufacturer information, measurements aboard and qualified marine review.
