Before you start
Gather the appropriate supplies and review the specific equipment manual.
- Current local guidance
- Charts
- Tide tables
Step-by-step instructions
Identify the actual recommended pass
Use official charts and trusted local notices rather than copying an old GPS track blindly.
Study tide and current
Check depth at the expected entry time and whether current opposes incoming seas.
Choose visibility
Prefer suitable daylight and sun angle when shallow hazards must be seen by eye.
Prepare a lookout and speed limit
Have a clear communication method and plan to turn back if uncertain.
Monitor independent evidence
Cross-check chartplotter, sounder, visual cues and any reliable local channel marks.
Safety note
Breaking water over a reef can be fatal. Abort if swell, visibility or uncertainty exceeds your boat and crew limits.
Key takeaway
The safest pass is the one verified for today, not just drawn on a plotter.
