author
Best remembered as a contributor to the classic sporting work Yachting, this late-Victorian writer brought firsthand naval and sailing experience to his subject. His surviving published record is slim, but it points to a life closely tied to Britain’s yachting world.

by Earl Thomas Brassey Brassey, R. T. (Robert Taylor) Pritchett, C. E. Seth-Smith, Sir Edward Sullivan, Watson. G. L. (George Lennox)
C. E. Seth-Smith is credited by Project Gutenberg as one of the contributors to Yachting, Vol. 1, part of the well-known Badminton Library of Sports and Pastimes. In that volume, he wrote the section titled "Corinthian Deep-Sea Cruising," which suggests a practical, experience-based interest in offshore sailing rather than purely armchair commentary.
The book itself identifies him as C. E. Seth-Smith, C.B. and describes him as late commanding London Brigade Royal Naval Volunteers. That places him in the late 19th-century British naval volunteer world and helps explain the confident, technical tone associated with his contribution to a major reference work on yachting.
Reliable biographical information about him is limited in the sources I could confirm during this search, so a full life story would be hard to state with confidence. What can be said is that his name remains attached to an enduring maritime title that continued to circulate long after its original publication, keeping his work visible to modern readers interested in sailing history.
