The Ripest of Apples appears in Sam Henry's Songs of the People p 383 with alternate titles of Tarry Trousers, I Drew My Ship into the Harbor, Love is Pleasing, and Rattle on the Stovepipe. He only gives two verses one of which reminds one of Carrickfergus or The Water is Wide.

O, the ripest of apples, they must soon grow rotten'
And the warmest of love it must soon grow cold
And young men's vows they must soon be forgotten
Look out pretty maiden that you don't get controlled

The seas are deep and I cannot wade them
Nor have I nor ever the wings to fly
I would that my love were a jolly boatman
To ferry me over my love and I
