Those are Fassmer lifeboats.
The accuracy on the drawings could have been better, but at so small scale, it can be hard to get it just right.
Quite true, I did re-do most of it as it didn't look quite right, but then again I didn't find a strait view of the side so I had to embellish a bit.
It's weird on a forum like this, that none have drawn lifeboats from other companies. I started with the Norwegian NorSafe (bellow) and hoped other people would follow up with something from there country.
Yours where the only ones I could find for my "mega" cruise ships and after trying those on, it simply looked ridiculous, even after editing them to be bigger.
The interesting fact I found out about these is that according to international law lifeboat capacities aren't supposed to exceed 150.
The SOLAS regulation on Life Saving Equipment (LSA) code 126.96.36.199 Mega Lifeboatstates: “No lifeboat shall be approved to accommodate more than 150 persons.”
