I propose a new rating system to help us communicate better about our local paddling conditions. It is not enough to just know that it is blowing 25 from the SW. We face a complex set of interactions between earlier winds, tides, boat wakes, and our mysterious submarine wakes. Some days we paddle easily into a 15 knot freshet and then speed down easily linked 13 knot waves made of liquid jade. Other days we beat our heads into 30 knot winds with our hulls slapping, only to turn around into a jumble of chaos despite how great the waves looked going upwind. What I propose is that along with wind speed and direction we can report a ratio of “Work to Fun.” For example, If you felt you worked about as hard as expected for the quality of waves (like today at about 11:00) you would report a WTF of 1. However, if you found you needed to work twice as hard as expected for the quality of the waves you would have a WTF of 2. Whereas, a session where you paddle upwind only to find the downwind waves twice as good as you usually encounter after such an upwind (a powder day) would result in a 0.5 WTF. This ratio based system offers two huge advantages. #1: it is completely open ended, so there is always the possibility of a higher WTF. #2: It is entirely subjective, which means it is infinitely debatable. This means it can assure hours of post paddle entertainment as we compare our assessments and sandbag and exaggerate to each other about the conditions we encountered.

Great idea. I think a simple, 5 star pleasure rating - 5 being the best, would be easier for us simpler minds to grasp, fractions never being everyone's favourite​. I like the WTF name, but a WTF of 5 might be confusing - is it good or bad

This is a great idea, but the equation needs another set of variables to be completely descriptive. For example, as it stands now, a WTF of 1.0 could mean that that the waves were horrible, but there was no wind to deal with. It could also mean that the waves were amazing, but the wind was a real SOB. In other words, a flat day and a raging day could both have a WTF of 1 and WTF is up with that? As a person who writes algorithms for a living, that doesn't sit well with me. Let me cogitate on this.

Arrgh!! you guy's are hurting my brain!!

I second stars. And for those who want more detail, maybe we just start doing yelp reviews for conditions.

On the snow side of things, there's “Larry the Powder Guy” who is a meteorologist and issues excellent email alerts for what to expect. Maybe we could get him into paddling?

John,
My proposal was to add the WTF rating to the wind speed and direction. This makes it similar to a wind-chill rating. It drives me to distraction that we now see weather reports that only mention the wind-chill number. I for one will make different recreational desisions around a wind-chill number of -20 degrees if it means a clear crisp windless day at -20 vs. a 30 degree day with a 70 mph wind. Similarly, the WTF rating offers the chance to provide useful information when accompanied by other data, or it can alternatively be used to agrandize an otherwise unremarkable situation, which may be its most useful feature at avenue bread. As this is a WTF rating, I don't really see using it much for values much under 0.7. We already have a useful adjectival rating system for that range (awesome, epic, etc.). For those of you trained to evaluate your desisions based on a 5-star system, I propose that everything under a WTF of one could be discussed in stars if more comfort is provided. It is in the real WTF conditions for which we need the ratio to describe our experiences. For those afeard of math I propose that a WTF can easly be stated in a simple “2 to 1” or “3 to 1” style to avoid the confusion that a decimal might introduce.

the only problem with this system is the worse the day the higher the number which is counter-intuitive.

WTF ?

I must admit that is a feature not a bug. The idea is to have higher numbers if it is more WTF.

The benefit of having the higher number for bad conditions is that conditions can usually be worse with higher numbers. But on the other hand what constitutes a perfect 0 zero?

I believe 0, though mathematically feasible may be against the laws of physics (something like perpetual motion). However, not wanting to discount the indomitable human spirit, it sounds like the rough equivalent of Zen enlightenment. But achieving this state will take practice and focus, Grasshopper.
