Lol, PoI--what would they gain by that?

That's really funny.

^ooh, good question....I shall ponder this...

And the voice warned him not to attempt this peril; for his strength and skill would not be able to build any ship able to dare the winds and waves of the Great Sea for many long years yet. "Abide now that time, for when it comes then will your work be of utmost worth, and it will be remembered in song for many ages after." "I obey," Cirdan answered, and then it seemed to him that he saw (in a vision maybe) a shape like a white boat, shining above him, that sailed west through the air, and as it dwindled in the distance it looked like a star of so great a brilliance that it cast a shadow of Cirdan upon the strand where he stood.

"Abide now that time, for when it comes then will your work be of utmost worth, and it will be remembered in song for many ages after."

Among them the tradition is handed down from Elanor that Samwise passed the Towers, and went to the Grey Havens, and passed over Sea, last of the Ring-bearers

Then Legolas bilt a grey ship in Ithilien, and sailed down the Anduin and so over Sea; and with him, it is said, went Gimli the Dwarf. An when that ship passed an end was come in Middle-earth of the Fellowship of the Ring.

Hope that clears a few thigs up.

The final two Ringbearers had yet to pass across the sea, but in the sixty-second year of the Fourth Age of the Sun, Samwise Gamgee, faithful companion of Frodo Baggins, arrived in Mithlond, and he and Círdan sailed away on the last of the ships built by that great shipwright upon those shores. And so in the end, the words of Ulmo were proved truthful as well, for that Vala had warned Círdan not to fare over the sea then, but instead to wait and work upon the shores of Beleriand and Middle-Earth, and he had obeyed through all those long years, though kin and friend had passed before him, even though the longing for home had engulfed his heart those long years.

For Ulmo had said unto him in a dream, "Abide now that time, for when it comes then will your work be of utmost worth, and it will be remembered in song for many ages after." And Círdan had sworn to obey, though his kin sailed ahead of him, and he had wished to follow. Yet in return, Ulmo's words had been the truth, for none shall forget the Shipwright and his deeds upon these shores, not while others still live to remember him and tell the tales of his greatest deeds.

Cirdan remained behind at the Grey Havens to await the departure of the Elves who still lingered in Middle-earth at the beginning of the Fourth Age. It is believed that when the Last Ship finally embarked from the Grey Havens, Cirdan himself was able to sail to the Undying Lands.
