On a perfectly flat day, they would each have to be almost 46 feet above the beach.

Believe it or not.
"NOT" ...In fact, if the forum members were about 6 feet tall, they wouldn't need ladders. Over 16.6 miles, the earth will curve 11.039 feet. Check your math!

Think about it. If each person was 46' above the shore, that would equate to over 5 feet of curvature per mile. (92 ft/16.6 mi = 5.5 ft/mi) If that were the case, a person standing on the northern tip of Rattlesnake Island wouldn't be able see a 10 foot high boat along the shore of Welch Island, 3 miles away.
