95. The highland near Douglas Harbour should not be visible from the coast of North Wales, and a 50 mile stretch of Welsh coast would not appear flat on a spherical Earth

"On a clear day from the highland near Douglas Harbor on the Isle of Man, the whole length of the coast of North Wales is often plainly visible to the naked eye. From the Point of Ayr at the mouth of the River Dee to Holyhead comprises a 50 mile stretch which has also been repeatedly found to be perfectly horizontal. If the Earth actually had curvature of 8 inches per mile squared, as NASA and modern astronomy claim, the 50 mile length of Welsh coast seen along the horizon in Liverpool Bay would have to decline from the center-point an easily detectable 416 feet on each side!"

Dubay again fails to take into account the elevation of the observer and that the Earth is huge.

Dubay does not mention from where on the Welsh coast the Isle of Man is visible, but I have found independent testimonies of the Isle of Man being visible from Great Orme's Head, so we will use that.  If you use the correct calculations  we find that we fully expect the Isle of Man to be visible on a spherical Earth.

Great Orme's Head has an elevation of 679 feet.  The highest point on the Isle of Man is Snaefell at 2037 feet.  At a distance of 70 miles only 967 feet of the island would be obscured making it clearly visible on a clear day.

A maximum of 526 feet of the Isle of Man would be obscured.  Since it has a maximum elevation 2034 feet, we can see that on a clear day it would definitely be visible.

Regarding the second claim, this is similar to proof 94.  Let us do some actual calculations, something that flat earthers rarely do, to see how much the curve of the earth would be visible along this stretch of coast to an observer.


Using an accurate distance between the Point of Ayr and Holyhead of 54 miles, the drop that is visible at the Point of Ayr and Holyhead is approximately 486 feet.  Greater than that calculated by Dubay.

For simplicity sake we will ignore the fact that from Douglas we are looking at the Welsh coast at an angle and assume that we are looking at it straight on.

This would make the distance from Douglas to the ends of the stretch of coast 64 miles.

Next let us consider how much lower that would make the angle of our view when looking at the ends of the coastal stretch compared to looking at the centre.  I.e. how much of a different angle do we have to look at for an 486 foot drop at a distance of 64 miles (337,920 feet).

Using simple trigonometry we can work it out to be 0.0824 degrees!  No-one could possibly hope to notice that with the naked eye.

Once again if we do the calculations Dubay's claims are easily shown to be bogus.  The coastline would definitely appear flat on a spherical Earth.
