Eämbar
From Tolkien Gateway
A ship built by Aldarion to act as a Guildhouse for the guild of explorers known as the Venturers. It was designed also as his own dwelling-place, hence its name, which means 'sea-home'. Originally anchored off the island of Tol Uinen in the bay of Rómenna, it was later moved to a new anchorage off Andúnië.
