This session will use professional analysis tools to break down an offshore race, using the JOG Weymouth Race as a practical case study. You’ll learn how to reconstruct the weather, review routing decisions, and analyse performance data to identify key tactical moments and opportunities for improvement.

The 50 NM JOG Weymouth Race runs from Cowes to Weymouth on April 18th, featuring two full days of racing. The course takes the fleet past the Needles, around the Shingles, and back to Weymouth.

We will analyse Expedition log files from a Sun Fast 3300 (mid-fleet) and a Sun Fast 3600 (top of the fleet) to explore the post-race analysis capabilities within Expedition, as well as what can be achieved using proprietary software. You’ll gain insights into decision-making, tactical choices, polar updates, and instrument calibration — and how all of this can sharpen future performance.
