I’m about 5’ 7” depending on my chancletas or flat footing it, and I’m usually right at or sometime in the water up to my shins, so it’s safe to say I am usually accurately right at sea level…. so I usually use where the sky meets the ocean horizon line to gauge punts like this one here. Even though it’s considered “above the lip surfing” when I see peeps boosting above that straight line in the background, going near OR well above, it’s a pretty big air in my opinion!
