At the end of Return of the King it implies that Legolas built his ship on the day of Aragorn's death and sails west, but to me that just doesn't work. I think one of two things must have happened either he was already building it or started building it on March 1st and left when it was completed. Its also implied he took his people with him so it must have been a reasonable sized Vessel and now some kind of rowboat. My favourite theory is that he was already building the vessel along with this people, ready for when Aragorn died. What to people think?
