Here's my finished design of the Proposed RMMV Oceanic (1928) of White Star Line coming in at 544 blocks long. Built to a 1.7 - 1 Scale. Though the original plans never showed a curved front super structure the many 3D renders people have done convinced me to go with that design.

If there's enough interest a video on Youtube could follow.

The RMMV Oceanic (Royal Mail Motor Vessel) was the planned name of an unfinished ocean liner that was partially built by Harland and Wolff for the White Star Line. It would have been the third ship bearing the name Oceanic, after the one of 1870 and the one of 1899. It was envisaged in 1926, with the idea of modernizing the transatlantic service of the company. The planned size of the project increased, until it became that of a large ship destined to be the first to exceed the symbolic limit of 300 meters (1000 feet) in length and 30 knots in speed..

After several years of study, the construction begin in June 1928 in the Harland & Wolff shipyards in Belfast. However, the work was carried out at a slow pace and ceased in June 1929. The Great Depression which broke out the same year put a definitive end to the construction, for which the government refused to advance funds.

Within the White Star Line fleet, the Oceanic was thus replaced by two smaller ships, the Britannic and the Georgic, both inspired by its profile.
