### 1/5 — Less stations

*2026-08-15, version 7.10*

Been using sail flow for more than 15 years. Today I can no longer access any of the stations I always have without upgrading. Useless. Uninstalling. Way to go sail flow and put the screws to your most loyal users.

### 5/5 — Wind

### 2/5 — Used to love SailFlow

*2026-07-13, version 7.08*

I have been a Plus user of SailFlow for several years and have grown to rely on its information, however, when it automatically renewed last week I could not access any of my favorites for Hampton Roads as it said I needed to Upgrade to access them. SailFlow, you have just lost a user.  I will be cancelling my subscription and moving to Windy.
