Why one number
The same afternoon rides differently in a 20-foot bay boat than in a 36-foot center console.
Wind, waves, swell and current become a single score, hour by hour, for your boat. Not a generic sea state: the ride your boat will give you.

How it works
Eight screens, one ruler
Swipe through the screens →
Inshore
From the backwater to the blue water, scored for your boat
Harbors, sounds and rivers are scored on the same ruler as the open ocean, so the run across the harbor and the run to the ledge read the same way.
Spots
The best hours to run, at the spots you fish
- Save your spots and see their most comfortable days
- Alerts when a saved spot is forecast to ride the way you set
Helm
Your ride against the forecast, live
Live gauges on the water, and the forecast for the water around you kept on your phone when you lose signal. The hashmark is what the forecast said; the needle is what your boat is doing.
Helm
The Ride Rose: how the ride changes with your heading
Every heading, scored. Head seas, beam seas and following seas are not the same ride, and the rose shows which way is smoother before you turn.
Helm
Your ride on four gauges, live
Your ride, your speed, the hardest hit and the rose on one page, built to be read at a glance with a wet thumb.
Forecast
Wind, waves, tide and current, all in one place
Wind, gusts, wave height and period, swell and tide, in plain numbers. The traditional data is all there, under the score, when you want to see why.
BoatScore
A score built for your hull, sharpened by every ride
- Every boat gets a score from its specs, refined by your own rides
- A report for every trip, and a card you can share
- Recorded rides are uploaded to improve the forecast
BoatScore
RideScore rates the water. BoatScore rates the boat.
Your BoatScore is the roughest water, on the RideScore scale, that this boat can run in before its ride reaches Rough. Higher means a smoother-riding boat. One ruler for the water and the boat, so the two numbers can be read against each other.

Your ride in this boat
How typical days feel in this boat
The BoatScore page turns the number into days you recognise. For the 81 above, from a real boat:
- Water 25
- rides like 20
- Water 45
- rides like 33
- Water 75
- rides like 56
How the number is measured
Three stages, one number
- Modeled
- Estimated from your boat's specs the moment you add it: length, beam, deadrise, weight, power and hull. You see it right away, just for you.
- Blended
- Blended from your rides and your boat's specs, once you have recorded a few trips.
- Measured
- Measured from your rides. It gets more accurate with every ride.
Tested in lists the water your boat has actually been measured in: Calm, Moderate or Rough. Your boat's numbers change only for water you have run in, and RideScore never asks you to go out in rough water.
BoatScore is for powerboats. Every boat you add gets one, and each of your boats gets its own forecast.
The scale
One number for how rough it is
RideScore is the water. Your boat is the same water, scored for your hull. Four bands, and anything over 255 shows as 255+.
Calm0 – 30
Moderate30 – 60
Rough60 – 100
Very Rough100 and up
Coverage

What it is not
Comfort, not safety
RideScore forecasts how comfortable a ride will be. It is about comfort, not safety, and it never tells you whether to go out. It is not a navigation device and does not give routing. Always check the official National Weather Service marine forecast and use your own judgment.
