"[Item Transcription:] [Handwritten (in ink) letter on 'N. G. Herreshoff, Bristol, R.I.' stationery:] Dear Francis Lee,
I started to make a sketch for you of the 50in model yacht [#193204es], but after thinking it over a little decided it would be more interesting to make a model which perhaps w[ou]ld be better for you to look at than a sketch, as my eyes are not good at drawing any longer and I prefer to use tools. I did attempt to make a few calculations from pantograph sections which are on another sheet inclosed.
Perhaps the design represents a rather large body for the sail area but with the model lines carried out to include rudder, the wetted surface is not larger and with nearly 21lbs lead you could afford to set the sail rather high up and make it more effective in light breezes. However, I didnot [p. 2] make this for you to build from but only as a guide in carrying out your own design, which you should by all means do. Your head is overflowing with ideas of what a toy boat should be and you should go ahead and develop them.
When trying my 3rd toyboat 'TRILLIUM' [#193001es], I was very much impressed with the ease and dryness of decks when she went thru the seas and in this model I gave it the same type of bow.
It may not be good for a large vessel, as she would pound and throw spray probably, but it is certainly good for little ones.
Your affect[ionate] Uncle Nat
P.S. The model is to be sent by parcel post." (Source: Herreshoff, N.G. Letter to Herreshoff, Francis Lee. Halsey C. Herreshoff Collection at the Herreshoff Marine Museum Item MRDE02_02860. Folder [no #]. 1932-11-25.)
