I have been using CAD for about 10 years. I spent years before that drawing by hand, using pencil and vellum. While CAD allows for a neater and more accurate drawing, there is no substitute the hard work of fairing. I use waterlines, buttock lines, and diagonals to make sure that the hull is faired. It is a tedious process of going back and forth from body sections to sheer profile to half breadth, over and over, checking waterlines, buttocks, and diagonals. Move a little here, move a little there, go back and recheck, re-measure, look at the lines, and then when you are really certain that it all looks good, save and walk away, then come back tomorrow and check it again.
One book that I found very useful was Howard Chapelle's Boatbuilding. One chapter takes you through the layout and lofting, step by step of a small sailing craft. I also got a lot from reading Underhill's Plank on Frame Models volume 1. There are other books out there, but those are two of my favorites.

Your metal work is very nice. The pumps are amazing. Well done.

The deadeyes and lanyards look good. Nice work. Final tensioning later is a good idea. Things are likely to move around a bit between now and then.

Steve:
Your model is coming along well. Nice work.
Basswood is soft enough that it is liable to split. Any wood might split because you are making a piece in which some part of it will be have to shaped/sanded across the grain. That is what you having trouble with. A harder wood like cherry or boxwood will be less likely to split. Mahogany and walnut will most likely not work well as they are rather open grained. Beech would work, as will most other close and fine grained nut woods.
Years ago I made a scratch built cross section model and used crooks from smaller tree limbs to make my knees. It worked out very well and looked much more realistic. Without a table saw to slab off the thickness you need, it might not work for you.

Jack:
The drooping chain is actually not far from how it really works. Under sail, there is pressure on the mast and sails that will cause the bowsprit to work a bit so a little slack in the bobstay is to be expected. The slack will be taken up under pressure as the bowsprit works under sail.

Looks good. That is a nice piece of work on a complicated bit of machinery.

How to deal with badly drawn plans?
in CAD and 3D Modelling/Drafting Plans with Software

Ron:
I guess I took what I did on a drafting board (self taught draftsman) and began doing it in the CAD program. I have not gotten into 3D, although it sounds fascinating. I think the 2D three view fairing process is something in my comfort zone.
