Decision systems for offshore racing
Campaign Support
Prepare for the race you are actually sailing.
Race-specific weather briefings, campaign weather routing and Mini 6.50 roadbooks, built around your course, boat, schedule and operating constraints. We turn forecast uncertainty into clear decisions your team can use before and during the race.
Support formats
Choose the level of support your campaign needs.
Start with the smallest useful scope. Each service is tailored to the race and agreed before work begins.
Race Weather Briefings
Know what is likely, what remains uncertain and what could change the race.
Led by Marcel Korte. Live, race-specific briefings compare models, assess confidence and translate the developing weather picture into practical considerations for your route and start.
- Synoptic development and model confidence
- Routings based on your boat’s polars
- Key transitions, local effects and race risks
- Live calls with time for questions
Campaign Weather Routing
A dedicated weather and routing resource for the wider campaign.
Led by Marcel Korte. Support can run from initial route studies and departure planning through campaign-specific forecast analysis and routing, with scope and cadence built around your campaign and the applicable rules.
- Pre-campaign weather and route studies
- Forecast monitoring and alternative scenarios
- Boat-specific routing and scheduled updates
- Shoreside support during permitted phases
Mini 6.50 Roadbooks
Race-specific decision support designed for Mini constraints.
Developed by Joshua Weber. Each practical PDF is prepared before the start for use when onboard information and outside communication are limited, turning forecast scenarios and routing output into clear, leg-by-leg cues.
- Course, TSS and exclusion-zone overview
- Routing scenarios based on your polars
- Leg-by-leg wind ranges and decision points
- Indicators to watch as conditions change
Operating principle
Analysis should end in a decision.
More forecast data does not automatically create a better plan. The value is in knowing which scenarios matter and how to recognise them.
Boat-specific
We work from your course, polars, schedule and campaign constraints, not a generic regional forecast.
Uncertainty made useful
You receive the likely development, meaningful alternatives and the indicators that separate them.
Usable under pressure
The output is structured around timing, decisions and observable cues, so it stays useful offshore.
How it works
A clear scope before any analysis begins.
-
01
Brief us
Share the race, start date, boat type, available polars and the questions you need answered.
-
02
Define the support
We agree the deliverables, timing, update cadence and price before starting.
-
03
Build the decision system
We analyse the course, weather and routing scenarios, then deliver the agreed briefings, updates or roadbook.
