- Current tables
- Sunrise/sunset times
Step-by-step instructions
Identify the arrival window
Aim for enough daylight to identify marks, traffic and hazards, especially at an unfamiliar inlet.
Calculate conservative speed
Use a realistic boat average rather than maximum hull speed or a best-day log.
Include currents and detours
Add adverse current, tacking distance and approach time to the estimate.
Build a reserve
Plan for delays, reduced wind, sail changes and a second attempt if entry is unsafe.
Choose an alternate
Identify a safer waiting area or alternative port before departure.
Safety note
Do not enter an unfamiliar reef pass or bar solely because a chartplotter line looks clear.
Key takeaway
A conservative arrival plan offers options when wind, current or visibility changes.
