Two questions decide an offshore day. One app answers both, honestly.
Built for offshore pelagic fishing — bluefin, yellowfin, bigeye, swordfish, and the striper run closer to home. Where are the fish likely to be, and can your boat, with your fuel, your limits, and today's ocean, safely make the trip? Thermocline scores both, side by side, and never lets one hide the other.

Find the Fish. Run the Line.
Your boat. Our intel.
Satellite temperature breaks, chlorophyll edges, currents, the thermocline itself — fused into a glow of where your species likely sets up today, with ranked marks worth trolling.
GO, CAPTAIN'S CALL, or NO-GO — computed from your boat's real numbers against the live marine forecast. Every yellow names its reasons. Safety is never blended into fish enthusiasm.
The app calls you when the ocean opens
Watched windows
Pick a stretch of days. The server re-scores it against fresh forecasts around the clock and pushes when a day firms up to GO — or slips back.
Safe Reach
A live shape on the chart: the water your boat can actually work today, dented by the weather, honest about fuel and the ride home.
Run the Line
A time-boxed plan down the lit water — gray-light start, numbered stops, and the turn-for-home called before you need it.
The model grades itself
Every real catch replays against that day's satellite water — hits and misses both stay on the public report card. No competitor grades their own homework.
"Verdicts are decision support, not a guarantee. The gate can say GO and the captain still says no — that call is always yours. What we promise is that no number is hidden, no miss is buried, and the model never pretends to know water it can't see."
