About Tekkan (now Tecmo): Tekkan was established as a yacht management company in July 1967. In 1986, Tekkan decided to change their name to 'Tecmo'. In 2010, Tecmo decide to merge with Koei. So, today the company is called 'Tecmo-Koei Holdings'.
In the old version (by Tehkan), the ship doesn't move during the attract mode.
