I have this book and am willing to lend it to anyone interested in marine navigation who is a member of the Vancouver Power and Sail Squadron.
The plan is to share a sailing-adventure holiday, re-tracing (if that is possible) the "course" of the Dulcibella in the 1903 English spy novel "The Riddle of the Sands" (about which see http://en.wikipedia.org/wiki/The_Riddle_of_the_Sands), by sailing from England to Germany, particularly through the shallow waters of the Frisian Islands, and, ultimately, back to England. We would need to charter a shallow-draft vessel. This would be a voyage for real sailors and navigators, although we might do it in the summer instead of (as was the case in the novel) mostly October. Price: currently unknown. Timing: currently unknown. Skill sets required: seamanship, navigation, cooking...Number of sharing parties wanted: perhaps 4-6. Pic is from Wikipedia's photograph of a first edition of the novel.
