Ready to take your instrument data to the next level? Peter Isler has decades of experience in working with and getting the most out of sailing instruments. In this course, he will share his refined system and approach in tuning and instruments.

Course Goals:

  • To understand the basic structure and components of a racing sailboat’s instrument system
  • To understand the real world challenges of measuring position, wind and boatspeed and in calculating True Wind and Current.
  • To understand how to configure hardware and sensors for repeatable and accurate measurement.
  • To understand the sequence and procedures for calibrating the instruments so as to be able to measure boat performance relative to the wind.
  • To understand the real world challenges that require calibration to be an ongoing process.
  • To gain a understanding of sailing instruments and their calibration to be able to tune, maintain and use their information to aid in navigation and tactical decisions and improve sailing performance and polars. 


Peter Isler



Through a lifetime of sailing including seven America campaigns, an Around the World race, and racing on innumerable grand prix sailboats. Peter Isler has learned a thing or two about sailing instruments. In his Cup campaigns he worked with two of the legends of sailing instrumentation: Graeme Winn (Deckman, WTP) and Dick McCurdy (Ockam). His friendship and sailing with the likes of Stan Honey (Honey Nav), Nick White (Expedition) and Artie Means (WaypointRacing) has furthered his knowledge of this subject.
