Offshore Fishing Charts and Deep Analytics

Offshore Fishing Intelligence
for Serious Anglers

Rigline is an offshore fishing app that turns satellite oceanography into practical fishing intelligence. Track sea surface temperature breaks, scored offshore hotspots, weedline forecasts, inshore models, and 10+ ocean data layers in map-ready charts before you leave the dock.

What Rigline Does for Offshore Anglers

Rigline combines offshore fishing analytics, ocean charts, and trip logging in one platform. Raw satellite and model data become ranked, map-ready fishing decisions for offshore and inshore anglers.

Temp Breaks

Real-time sea surface temperature analysis finds offshore temp breaks and thermal fronts. Rigline ranks each break by strength and distance, then forecasts where the edge will be when you get there.

Weak, moderate, and strong break classification
Drift-corrected forecast lines
Nearest versus strongest break ranking

Deep Analytics

Multi-factor scoring combines SST, chlorophyll, currents, bathymetry, and more into ranked offshore fishing hotspots. Species profiles for pelagics, mahi, and wahoo add regional tuning by state.

Ranked hotspot zones with confidence scores
Species-specific weight profiles
Persistence tracking across runs

Inshore Intelligence

Estuary-specific modeling for inshore waters factors in tides, wind, salinity, clarity, habitat proximity, and structure to score hotspot cells by region and target species.

Tide-modulated hotspot scoring
Region-specific models for Tampa Bay, Chesapeake, and more
Seasonal species gating

Weedlines & Drift

Surface current convergence blends with sargassum signals to predict where floating structure sets up. Forecast steps help offshore anglers plan around the next 12 hours of drift.

Ocean Charts

Browse the raw ingredients behind the score, including SST, chlorophyll, altimetry, currents, salinity, mixed layer depth, upwelling, and more. Each layer includes legends, history, and forecast controls.

10+ oceanographic data layers
Near-real-time and forecast views
Source freshness and quality metadata

Trip Logging & Community

Log trips with GPS tracks, catches, conditions, and gear. Build your fishing logbook, track patterns over time, and connect with the Rigline community.

Catch and gear performance logging
Community feed and notifications

How Rigline Works

Heavy geospatial processing happens off-device, so your phone stays fast while Rigline does the hard work of turning ocean data into fishing intelligence.

01

Satellite and Sensor Data

We ingest offshore ocean data from multiple sources, including NOAA SST, GOES imagery, Copernicus oceanography, ERDDAP, and more, on a continuous basis.

02

Analysis Pipelines

Automated pipelines process raw data into thermal gradients, convergence zones, scored hotspots, and species-tuned models with built-in fallbacks.

03

Actionable Maps

Results are delivered as map layers on your phone, ranked, scored, and ready to use so you can make offshore decisions faster.

Sources include NOAA MUR SST, GOES SST, Copernicus ocean models, ERDDAP, and HYCOM, with automatic fallbacks when any source is unavailable.

Role

Self-Taught Developer

I built Rigline because the offshore fishing world had no good way to use ocean data. Sea surface temperature, chlorophyll, altimetry, and current data all existed, but none of it felt accessible or actionable for anglers.

As a lifelong fisherman from North Carolina, I spent years wishing I could see where temp breaks were forming, where convergence zones were setting up, and which offshore areas were actually worth the run. While studying Finance at LSU, I taught myself to code and started building the tool I wanted to use.

Rigline processes real oceanographic data through scoring and modeling pipelines, then delivers the results as map layers you can actually use on the water. No guessing, no static charts, just current ranked intelligence for offshore fishing.
