One platform, two surfaces: the phone works the race afloat, the web is home base ashore — one account, one checked nav library, one grounded brain, closing the loop from curate to debrief.

One platform
Afloat · the phone
SailFast aggregates the boat’s instruments into one feed, works the race live, and captures the telemetry as it goes.
Ashore · the web
The web is where the platform is set up and tuned — venues, courses and prep, the sim, and Hughie, with the debrief to come as the loop closes.

The origin
The instruments were never the hard part. Aggregating a feed, working the line, reading a layline — sailors have had those numbers for years. What nothing did was close the loop: curate the venue and the course ashore, rehearse it, ask a grounded brain, sail it, and read the race back afterwards, all on one account against one checked library.
SailFast is that loop. The instruments are the on-ramp; the recorded race and the one platform around it are the point.

01On the water
Afloat, SailFast aggregates the boat’s instruments into one feed and works the race in real time — the start line, the beat, each mark rounding. Where there’s no instrument network, phone GPS carries the start timer, the line and course navigation on its own. The instruments are the on-ramp; working the whole race is the job.

The guidance is advisory — it shows the call and the reasoning, and leaves the decision to the crew.
02The record
This is the part nothing else does. Every race is written to its own database at 1 Hz, and a live tactical-analytics engine reads it back as it runs — the cost of each tack and gybe, the shifts and their oscillation, the gap to target VMG, tack advantage, the effect of the current, broken out per leg.

03Ashore
Ashore, the web is where the platform is set up. One curated, checked nav library sits behind every boat — marks and courses reconciled against real nav-data, moved candidate → promote through the workbench, then synced to the phone. Amend and share them, across as many venues as the fleet races.
Marks and courses reconciled to real nav-data and AtoN, promoted through the workbench candidate → promote gate, then synced to the boat — amend and share, multi-venue.
Preview a course and activate it for the boat, then rehearse it in the sim — which runs the same race pipeline the app sails, so practice matches the real thing.
Follow venues and series, and let Up Next surface the race in front of you — the home base for everything before the warning signal.
04Hughie
Hughie is a fact-only tactical kernel: it reads the same numbers the platform computes and never invents them. Advisory by design, it answers from checked, multi-venue knowledge — where the data runs out, it says so. It’s live on the web today.
Every figure Hughie gives traces to a real data call. It reasons over the platform’s own numbers rather than guessing — a grounded kernel, not a glib chatbot.
Venue-by-venue tactical knowledge built from checked sources — each claim carrying where it came from and how much weight it deserves. Where the record is thin, it says “don’t know.”
Ask Hughie ashore today. It advises — it never takes the call off the crew.
On the horizonHughie is heading into the boat next — spoken, hands-free, with a suggested route to read alongside the crew’s own call.
