On the MSW forum, they pointed out to me that the height of the masts was insufficient, which I calculated according to the table in the book "Mondfeld - Historical ship models" and the dimensions fit the plan. However, the lower sections (mainmast, foremast, mizenmast) still seemed short to me. I compared the masts to the Zeehaen plan masts and they came out about 10 percent longer. So the masts are extended..
The Main yard and Fore yard locations will now sit as well..
