The desktop loop

From first question to a boat-ready plan.

The desktop experience is being shaped around the moments where a larger workspace earns its keep.

Research the trip

Compare target species, range, bottom shape, weather windows, and the cost of making the run.

Build the plan

Use private marks, routes, Captain Brad, and saved trip history to narrow the highest-value options.

Prepare for low service

Confirm the route and download supported map areas before relying on a connection offshore.

Carry it onto mobile

Use the same Fish Fathom planning system when the work moves from the desk to the boat.

Follow the build

Desktop is becoming part of the Fish Fathom story.
