Go or No? Marine Boat Weather

Go or No turns the marine forecast into a decision.

Instead of making you stitch together wind, waves, and tide tables, it gives you one clear answer: is it a good day to head out — on YOUR boat, today, from your spot?

ONE CLEAR ANSWER • A 1–10 boat-safety score with a plain GO / CAUTION / NO-GO verdict • The score adapts to YOUR vessel — powerboat, sailboat, kayak, or other • Set your length, engines, and horsepower and the score tightens or eases to match • A kayak needs far calmer water than a big powerboat, and the verdict knows the difference • A "now vs. later" read, e.g. "Light chop now — choppy by mid-afternoon" • No black box — tap any verdict to see the why: the reasons, the numbers, and the charts behind it

MARINE CONDITIONS • Wind speed, gusts, and direction • Wave and swell height and period • Water (sea-surface) temperature • Fog and visibility • Cloud cover

WEATHER • Current conditions, hourly, and a 7-day forecast • Barometric pressure with a rising or falling trend • UV index, humidity, and sunrise / sunset times

TIDES • High and low tide times and heights from NOAA (US coastal) • A tide curve for the days ahead

ANY HARBOR, ANY SPOT • Search any harbor, town, or beach by name and save it • Or drop in exact coordinates, or just use your current GPS location • Keep the places you fish and boat one tap apart and switch between them

BUILT FOR THE HELM • Dark, glare-friendly design that won't blind you at dawn or burn your eyes at night • Big type and glanceable cards, made for a one-handed check underway • Your units, boat, and saved spots stick — set them once
