Hey Clayton,

Like the boy said, PHRF is time-on-distance.

PHRF boat 57 would cover the SAME DISTANCE in 57 minutes
that PHRF boat 84 would cover in 84 minutes.

You can whip out the quick fraction 57/84 which gets about .68, giving you a rough estimate. So, say, you're 84, and you get around the buoys in 40 minutes. the boat 57 would have to give you 1.68 times that number, roughly. So you say 1.68x40, or 67.2. Subtract the diff, which is 27.2.

So, in this instance, boat 57 would have to finish 27.2 minutes faster than you did, at your 40 minutes, to win the race.

I think.

At least that's how I've been understanding the thing...
