1
Draw the route you intend to take.
Use ordered waypoints and stops. The distance shown is the length of your sketched route, not directions or a claim that the route is navigable.
How it works
Plan the trip. Check what matters before departure.
Draw the route you intend to take, add the timing, boat, and people aboard, then create one saved pre-departure review. Seaward brings notices, weather, tides, currents, local guidance, assumptions, and source links together around that plan.
Current source coverage focuses on U.S. coastal waters.
2
Add the trip details that affect the review.
Set the date and timing, boat, people aboard, experience, local familiarity, and any constraints you want the Brief to consider.
3
Create and review the Seaward Brief.
Read the notices, weather, tide and current information, local guidance, assumptions, questions to recheck, and source links before making your own departure call.
The Seaward Brief
One saved review for this trip.
Your route and trip details
Local Notices to Mariners near the route
Marine weather for the relevant forecast zones
Tide and current information when applicable
Coast Pilot and local-area notes
Assumptions and questions to recheck
Source links and freshness details
The Brief does not make the call.
It shows what Seaward found, what remains uncertain, and what you should recheck. You decide whether and when to depart.
A float plan serves a different purpose.
It gives a trusted person ashore the route, timing, vessel, people-aboard, contact, and safety details they may need if the boat is overdue.
