Android apps for Sailing/Racing

If you have an Android smartphone, these are the sailing/racing apps I use and recommend:

• Beer Can Racer
  Tactical racing app, much like a held-held GPS but with racing specific features. Excellent, but still a work in progress.
• EarthNC
  Display of NOAA raster marine charts. Excellent, but still a work in progress.
• Marine Traffic
  Displays real-time data for (mostly commercial) vessels with AIS. Excellent, but still a work in progress, try the mobile website as well.
• Tide Prediction
  Best of the (mostly mediocre) tide apps for Android.

Also useful (when you have a data connection) are these mobile websites:

• NDBC mobile (real time data from buoys)
• NOAA mobile (weather related information)
• PORTS SF text screen (real time data for San Francisco Bay)

So which Android smartphone do I use?
Nexus S, pure Android, best smartphone for my needs.
