How It Works
Three steps to safer boating
Add your launch sites
Pick from curated boat ramps and marinas, search by name, or drop a pin anywhere on the coast. Save your favorites for instant access.
Check conditions instantly
We pull wind, waves, tides, fog, UV, water quality, lightning risk, and more from NOAA, NWS, and EPA — updated every 30 minutes.
Get your go/no-go score
Every signal is weighted and scored for your vessel type and experience level. One clear answer: GO, CAUTION, or NO-GO.
Data Signals
16 signals. One score.
We aggregate every available public data source so you don't have to check five different websites before heading out.

Scoring Engine
Transparent scoring.
No black boxes.
Every signal is normalized to a 0–100 scale based on your thresholds and vessel type. Then weighted by importance and summed into a single score.
You see exactly why you got your score. Customize thresholds — maybe 4-foot waves are fine for your 28-footer but not your kayak.
Hard vetoes (small craft advisories, gale warnings, high lightning) override the score entirely. Safety first.

Features
Everything you need to decide
Built by boaters who got tired of checking five websites and still getting surprised at the ramp.
Plan ahead
Set a trip for this weekend. We'll monitor conditions and alert you if things change from GO to NO-GO — so you can adjust plans, not discover problems at the ramp.
Compare launch sites
See all your saved sites ranked by today's conditions. The best option floats to the top. Tap into any site for the full signal breakdown.
Smart notifications
Choose your alert level — just GO/NO-GO flips, all caution transitions, or every meaningful change. Defaults to what matters: will your trip still work?
Your vessel, your thresholds
A kayak and a 30-foot sailboat have different limits. Pick your vessel type for smart defaults, then customize any threshold. 4-foot waves might be fine for you.
7-day forecast
Detailed conditions for 3 days, simplified outlook for 4 more. Confidence indicators show when forecasts are reliable and when they're guesses.
Travel time factored in
What's the point of perfect conditions if it's a 3-hour drive? Real-time traffic is factored into your score. Closer sites with good conditions win.
