Mike, Brad, Frank. You could always take this up with the Author. Tom Cunliffe spoke at Humber Yawl Club last year, and he seemed quite approachable. His website is easily found. http://www.tomcunliffe.com/ The same advice appears in the 2010 Edition of Celestial Navigation although the sentence and paragraph does go on:
“….take your sight, assuming of course that the horizon itself wasn’t obscured by a distant wave of a similar height. This is a moot point, but rather an academic one. In such weather, sights are not super-accurate anyway and your assessment of fix accuracy will reflect this.”
If this last bit isn’t in the 1989 Edition, it’s possible someone has already queried the original statement. DaveP
