I thought so too (though as a FD, I figured they'd be legit).
Tossing out the outliers, there seems like there's a cluster in that area and a cluster a notch below:
4.44
4.43
4.25
3.7
3.49
3.37
3.3
3.2
It's been torrential here for most of the past 45 minutes--hardest of the entire weekend as near as I an tell.
4.43" with nearly a.25 in the last 30 minutes.
I'd imaging s/he was pretty banged up. Getting hit by something that large at whatever speed the boat was going (let's say it was 30mph) is going to do some damage.
So sad--thank you for passing this along.
Lift a glass to James and the great Cape Cod blizzards of past, future, and imaginary that gave him such excitement.
