Service by service
PredictWind
Where it leads: waves by hull shape and the boat's motion, a 4-day departure planner, briefings written by an AI, polars learnt on board, a satellite connection, and 1.7 million users claimed.
Where Saily WR leads: 21 public models routed against 6, each named with its run, free where its routing starts at $249 a year.
NavimetriX
Where it leads: ensemble routing with a confidence corridor, a fine model chained into a broad one, the best departure, waves in the computation, coastal routing on C-MAP charts with the tide, an AI briefing and tools for on board.
Where Saily WR leads: one route per model, computed on the server all at once, nothing to download, and free where NavimetriX costs €79.99 a year.
SailMeteo
Where it leads: its ranking of departure slots, waves and gusts in the decision, offline areas, rated anchorages and an iOS app.
Where Saily WR leads: a weather pipeline of its own with 21 models against 11, routing over the whole grid, depths in the computation, and five languages where SailMeteo speaks French.
SailRouting
Where it leads: iOS and Android apps, and departure dates compared in the app.
Where Saily WR leads: no account and no 200-mile limit, 21 models against one or two, depths in the computation, and the polars of the ORC boats.
OpenSail
Where it leads: a departure planner, comfort modes, a gust ceiling, model agreement along the route, explained refusals, AI briefings and a public API.
Where Saily WR leads: 21 models against 3, ECMWF at 0.1° on its four daily runs, one route per model, and no account where OpenSail gives one free GFS route a week.
Squid
Where it leads: about 50 forecasts with ensembles, observations (satellite, ASCAT, stations), tools to compare scenarios, and GRIB over Iridium.
Where Saily WR leads: free on every model where Squid charges €9.98 to €69.98 a month by area, and nothing to install.
Orca
Where it leads: a complete navigation system, rerouting under way, bridge clearance, locks and canals, waypoints, GPX import and sending to the plotter, and a fine model extended by ECMWF automatically.
Where Saily WR leads: one route per model on 21 models at once where Orca routes on one blended field, free sail routing with no distance limit, any browser, more polars and five languages.
savvy navvy
Where it leads: a routing graph drawn from official charts (bridges, traffic lanes, no-go areas), a departure every 30 minutes, waypoints, full navigation, offline use and CarPlay.
Where Saily WR leads: 21 named models against GFS or an unnamed blend, one route per model, no account, and ORC polars rather than one derived from the waterline length.
