Choose the species and range before you study the map.
Start with the fish you are actually chasing, the ports you can run from, and the areas that fit your fuel, time, and crew.
Fish Fathom HomeSerious offshore workflow
Plan the offshore trip before you spend the fuel.
Fish Fathom brings the planning work into one mobile workflow: pick the target species and area, inspect structure, judge the weather window, save the route, download the map, ask Captain Brad, then review your private diary and catch patterns.
Premium from $5.99/mo or $44.99/yr. Built for planning, not scrolling.
Trip sequence
A real plan has a chain of decisions.
The value is not one isolated feature. It is moving from intent to route to offline readiness without losing the evidence that shaped the decision.
Inspect the bottom, contours, and nearby context.
Compare bathymetry, relief, hard-bottom clues, public survey context, and saved marks so every stop has a reason behind it.
Check whether the weather window supports the plan.
Review wind, seas, water conditions, and alerts before committing to a run that depends on timing and a safe return.
Save the waypoints, route, and offline map area.
Turn the plan into navigable marks, route legs, and downloaded map coverage before cell service gets unreliable offshore.
What the planner connects
Every planning layer answers a different offshore question.
Target species and area
Frame the trip around target species, likely depth bands, travel range, and the coastline or offshore grounds you can realistically fish.
Structure review
Use contours, relief, bottom context, and nearby saved history to narrow which edges, humps, ledges, and breaks deserve time.
Weather windows
Compare marine conditions, alerts, wind, waves, and timing so the plan fits the actual window instead of a stale hunch.
Routes and waypoints
Save marks, organize route legs, and keep the return path visible alongside the structure and conditions that shaped the plan.
Offline map downloads
Download the map area and supported layers before departure so core navigation context stays available when service fades.
Captain Brad planning help
Ask Captain Brad to compare your plan against map evidence, weather context, and your own fishing history when you choose to use it.
From research to execution
Turn map research into marks you can run.
A productive planning session should end with something concrete: saved waypoints, a route that respects the run, downloaded map coverage, and a clear reason for each stop. Fish Fathom keeps those pieces tied to the map instead of scattered across screenshots, texts, and memory.

Captain Brad
Ask a planning question with your own context behind it.
Captain Brad can help pressure-test the plan when you choose to bring in your saved waypoints, catch logs, diary entries, map context, and conditions. Use it to compare options, surface overlooked constraints, and turn a rough idea into a more defensible offshore plan.

Your diary and catch patterns make the next plan less generic.
Offshore planning gets better when the app can remember more than catches. Diary notes capture hunches, missed bites, changing conditions, crew observations, and decisions you want to revisit later.
- Private diary notes preserve trip plans, missed bites, lessons, and weather observations.
- Catch logs keep species, photos, locations, and conditions tied to actual outcomes.
- Saved waypoints and routes let the plan become a repeatable offshore workflow.
Before leaving service
Download the map area after the plan is worth running.
Once the target area, stops, and route make sense, download the supported map coverage before departure. Fresh connected layers and AI still require service, but your core downloaded navigation context is ready for the water.

Fish Fathom is for anglers who want structure, weather, history, waypoints, routes, and offline readiness in the same serious planning workflow.
