CLUSTER MARINE-BOATERS-NAVIGATION · 78 ENTRIES · EARLIEST ENTRY 2009-09-24

Marine navigation and weather apps

This cluster comprises marine navigation, weather, tide, and boating assistance apps, ranging from professional route optimization and AIS tracking to recreational chartplotting and fishing aids. Entries were added periodically across many months from 2009 to mid-2026, with mostly single entries per month and occasional pairs, though six members lack source dates. The traction leaders, each with zero stars, are coco-boat-ios, i-Boating, and iNavX.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
