For
Sailors planning coastal or multi-day passages
Worth noticing
A GPX track can be analyzed for upwind speed; the page says the track is calculated, not stored.

Field notes

The form lets sailors set vessel-specific limits, including draft, mast height, wind gusts and wave height; engine consumption and a 20-percent fuel reserve are also represented. Its own-track analysis is described as filtering out motor passages, manoeuvres and harbour time when estimating upwind speed. Route suggestions are expressly approximate, and the page directs users to check official nautical charts before departure.
