There is now no ship...

[William Cloud Hicklin]

Firstly, how could a ship bulit by Legolas get to the Undying Lands? Access to the Undying Lands in the Third Age was restricted exclsively to ships of the Falathrim elves.

Where in the world do you get this notion? Not only is it nowhere stated, but it's also a datum that (1) Legolas did it; and (2) many Nandor successfully sailed from Edhellond.

Moreover, 'Falathrim' was a meaningless term in the Third Age.
