Dimensions, here we have a mess

. Anyhow, dimensions are important for right proportions.
I found an original picture of America made a 15 years after 1851 run (at least was described like that).

Then after resize, I compared with some plans available in internet. In all comparisons, at plans bowsprit was longer and masts was longer, than in original old picture.
There are also differences between plans, however more or less they looks the same

Plans differ by bowsprit length and angle, and mast length

Finally I found picture of Yacht America replica from 1897 , and looks like all plans was made at base of this replica, in this case bowsprit and masts length more-less match the plans

As reference, pictures of original and replica comparison

As you see, is hard to choose how in fact this yacht was looking like, finally I choose plans mostly matching with original and replica, this plan I will use to estimate proper dimensions for 1:120 scale model

BTW I add also plans.zip file with all plans I collected for America, many differences between them, I am sure will be useful in future, and some old pictures also probably useful
