Our Mission

We believe everyone should have an accurate and beautiful map of the water around them.

Open Depths turns crowd-sourced soundings into trustworthly charts and uncovers the waterways you already know, and the ones you're about to.

  1. A good chart keeps you safe and helps you navigate with confidence.
  2. That chart exposes you to a world you can't see underneath you.
  3. To understand your local creek, river and waterway in a deeper way.

We hope that appreciate how the tide changes it daily, and it morphs from season to season.
