The sun, at zenith subtends an angle of about 0.52 degrees.

In RET, that's the size at the horizon too - but in FET, it **ought** to be smaller because it's further away - but we supposedly have magic perspective AND the magic-bright-object-size-fixer-upper - so it's the same size as it is at zenith there too.

So how high is a wave at the horizon? Well, if your eye was a foot above the water, the horizon would be 1.2 miles away (6336 feet)...the wave (even at 6' tall) would subtend arctan(6/6336) ...which is 0.054 degrees.

So a 6' wave on the horizon would only obscure maybe 10% of the Sun's disk. You'd need a 50' wave to cover it completely.

If your eye was closer than a foot, the horizon would be closer - so a smaller wave would do - but you'd literally have to get your eye within 1/10th of an inch of the water surface...and which point even the slightest ripple close to your face would block your view.

Sorry Tom...it's nothing to do with waves.
