[Mithalwen]

We know from the tale of Aldarion and Erendis that the elves of Aman could and did visit Numenor and that the men of Numenor could and did visit Middle Earth.

Now since the Numenoreans surely were originally taght shipbuilding and sailing by Cirdan's people prior to their leaving for their new land so the elves of Middle Earth must have the knowledge amd skill to build and sail ships to Numenor but did they? obviously it was not an insignificant journey but elves have time at their disposal. Now I must cnfess that I have not read every word of HoME and I may be missing something obvious. Were they under a ban?
