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.

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

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.

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.
