The short version

  • Only AccuWeather has a free tier, so it costs nothing to try first.
  • Each has a real cost: AccuWeather free API tier limited to 500 calls/day (14-day trial), forcing quick upgrade to paid plans; Sea Machines requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • They diverge on capability: AccuWeather covers RealFeel temperature, Sea Machines covers Autonomous control.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AccuWeather

  • Free API tier limited to 500 calls/day (14-day trial), forcing quick upgrade to paid plans
  • Entry paid API tier (Starter, $2/month) capped at 15,000 monthly calls with only Current Conditions and 5-day Forecast
  • Higher-tier forecast features (72-hour/10-day/120-hour/15-day forecasts, Alerts, Imagery) gated behind Prime ($250/mo) and Elite ($500/mo) API plans
  • Consumer app requires iOS 17 / iPadOS 17 / macOS 14 or later, excluding older Apple devices

Sea Machines

  • Requires hardware fitted to the vessel; the autonomy systems are retrofits or new build installations rather than a software purchase
  • Targeted at vessels from 10 to 300 ft, so it does not address the largest commercial tonnage
  • Pricing is not published and is arranged directly with the vendor
  • The SM300-NG is the class-approved unit, so the cheaper SM300-SP does not carry the same approval
