Courses begin with two three-hour theory sessions in the Colorado Executive Club Building, where 30–35 students learn about sailing terms, gear, and safety. After passing the final, they practice basic knots and sailing techniques in groups of four in three separate three-hour sessions aboard a keelboat at Cherry Creek or Chatfield Reservoirs.

Victoria Sailing School

Captain James Cook's nautical adventures have taken him from delivering yachts across oceans using only sextant navigation to earning the ASA's most-advanced instruction certification. Since 1986, he's channeled that oceanic expertise into Victoria Sailing School, where expert instructors help students of all skill levels earn ASA certifications and endorsements through hands-on techniques.

Before they set foot on a boat, however, aspiring seafarers get their feet wet in a safe classroom setting in the Colorado Executive Club Building. Upon passing their exams, they move on to practical sessions on the Cherry Creek or Chatfield Reservoirs, where they learn to tie basic knots or rig spinnakers on a J/22. More advanced students cut their nautical teeth on a J/30.

Along with sailing courses, 10-week coastal- and celestial-navigation classes help guests master the skills necessary for steering a course through the open seas, including an ability to decipher longitude, latitude, and the shouted, arcane demands of the moon. Weather for the Mariner classes teach students to analyze weather maps and prep strategies to avoid hurricane hazards.
