Windy API is leaflet.
So you can add your own baselayers at different zoom levels.
OSM tiles are free for most users.

Premium is good way to support developers, so they can give out most features for free.

All those maps are based on Windy API: https://api.windy.com/map-forecast
There are some official examples also available.

My site is tracker.ee, you can copy-paste some code if you want, just don't make visually identical clone :)

Multiple boats (race ended, so no active movements):

Single boat:
https://gis.ee/leaucommotion/

Probably most difficult part is getting data from boat.
For L'Eau Commotion Iridium Go was used.
Iridium Go has automatic reporting service via e-mail.
Server can fetch those e-mail reports and make it usable for Leaflet map (Windy API).
