A round-the-world sailor spent hours plotting courses below deck, then built the app he wished he'd had.

Loved and funded. A real wedge into a market Garmin ignored: simplicity for novices. But recreational boating is discretionary and seasonal, and the chart data underneath is rented, not owned.

Revenue is first-party but self-reported, not audited. The headline £1.5M ARR (about $1.9M) is the company's own figure for end-2022, verified in the raw HTML of two pages (its news page and Great Lakes Scuttlebutt). In its December 2025 Republic Europe crowdfund pitch the company self-reported roughly $3.5M ARR (B2C) plus a $2.1M B2B pipeline, and Latka estimates $2.6M revenue for 2023 — but the Republic page returned HTTP 403, so I could not open it to verify the $3.5M and kept it out of the headline. Downloads (3M+) and subscriber (15k+, 2021) figures are company-stated. GBP converted at about 1.25. We never score you.
