Stop guessing if the water will be good. Seascore turns complex marine forecasts into a simple 1–10 score that tells you how great the day is for getting on the water. Whether you’re cruising, fishing, sailing, or just heading out for a sunset ride, SeaScore analyzes the conditions that matter most: • Wind speed and gusts • Wave height and conditions • Marine forecasts • Hour-by-hour boating windows A 10/10 means it’s one of the best boating days you’ve had recently. A lower score helps you know when conditions may be uncomfortable or better saved for another day. Different boats have different needs.
