I ask the same question some days ago...
I downloaded the pack and i saw the yacht but i couldn't play it so i ask
And i find out that you can't play this old yacht if you don't have the Ship Simulator New Horizonts...
I paly it on my NH in 2006 and it's OK! But there mis the interior so isn't to much... and it's slow but it's cool...
It goes faster if you tug it with some ship than her self...
If you want this yacht you need to buy the Ship Simulator New Horizonts... because you can't buy just her in the Shipyard...
Good bye!
