Interesting question I had was how to draw this profile.  I basically considered it a slice right through the middle of the boat.  However, a side effect of this (with the deck camber) is that the railings shown should be reduced in height by about a planks height.  If you look at the top of the quarterdeck you can see the delineation of the planking, then the false deck, then the underlying fore and aft bulkhead.  By lowering the railings it would look like the railings are not on the same level with the quarterdeck which would be in error.  Interesting.  An option would be to omit the railing entirely but that might lead you to think the main deck was just like the quarterdeck (just flush).
 
Just as the top down view shows a width to the widest point, which depending on the tumblehome, can be in a variety of locations.
 
Drawing a set of plans for the first time has been very enlightening and I have a greater respect for the process.  I think this reliance on just one view sometimes led to the issues I identified (and fixed) with the prototype.
 
To jump start the bearding line I drew the main keel a plank's width below the lowest part of the bulkheads.  The primary bulkhead will be an 1/8" while the keel will be 1/4" thick.  My thought is that this will make planking cleaner.  In fact, all planking can be done prior to the affixing of the keel itself (remember POB).
 
Question:  Should I keep it like this or move the thickness of the keel up to the bulkheads to allow the bulkhead to have the bearding line custom cut?

Next step is to capture all the deltas in a new profile drawing (to include false deck and planking).  It is important that all the prototype measurements align with this capture (as much as possible - there is a deck slope port and starboard).  Once satisfied, I will start capturing the bulkhead profiles.  These will include fore and aft profiles per (capturing bevel amounts).

This will be the master to create the exploded component view - keel, fore&aft bulkhead, and eventually slot depths.
Whoops - Forgot to add the false keel.  Probably raise the height of the aft stem more into the hull (specific name escapes me at the moment).

Oh boy, big changes coming (I blame Druxey LOL).
 
Cleaning up the work area today and decided to do some comparing against Harold Hahn's Hannah plans.  From an above view pretty happy the comparison is pretty close and there is close alignment (frame width and spacing the same, etc).

The same can also be true from the side view:

The deck profile is almost scary on how close it is (I aligned at the keel).  The difference in the slope of the frames is readily apparent.  What I didn't think was that for the distance of the step up to the quarterdeck and for the railing posts, the difference really isn't that much.  The keel depth will be re-verified but is much deeper on the Chapman plans.
 
So.......I am going to redo the ship to have frames vertical to the keel.  This isn't as bad as it sounds.  I will redraw the profile and figure out the point for the bulkheads to pivot at (deck, waterline or keel).  I will then figure out how to mount to board so the bulkheads are still perpendicular to the slot cut in the board.  The existing bulkheads will be modified as necessary (shouldn't be much) to conform to the new design.  At the bow may need to recut one or two but time will tell. 
 
Sometimes you just have to do what you have to do LOL.  (again, thanks Druxey).  It will be a better model in the end.

I feel like I am posting the same pics over and over again but there are HOURS of work in between.  This series is called 'Almost There' haha.  I am thinking another solid day and this just may be.
 
Did some sculpting of the stern (again) but pretty complete.  I still need to add a block below the wing transom to allow shaping of the stern and better attachment for planking.  The bow is pretty set, with the exception of the bow block (same purpose) and a few other minor details.  I (of course) got messed up with the railing height (my template meant for above the false deck, started to apply without it so......some 'repairs' are required.  Final shaping of the bulkhead bevels are soon to come.

This process has been very educational (and frustrating) but getting back into the groove needed some re-education.  I am looking forward to the next step of a good set of drawn plans and then a full POB build to validate.

Alright, think I am at the end of the road for this prototype.  All outer bulkhead bevels added and the blocks shaped fore and aft.  I am not beveling the deck portion on this build.  I did have to add a 1/16" skin to a section of one bulkhead but other than that, everything worked out.

The blocks I kept putting off thinking they will require lots of carving, sanding and other.  In my mind they had grown into 1" by 3" by 5" monsters.  The truth very different.  Pretty straightforward.


I might add some dowels through the keel to keep it in place.   -Mark

I think I am left with beveling the lower frames, and adding a block at the extreme fore and aft for plank affixing.  Maybe this afternoon.
 
Added a false keel.  Had to cleave off the keel forward of the scarph joint (don't ask) so vertical line at V7F frame is this fix (ignore).  Everything appears ship shape and to plan.  Making templates coming up.....

No time like the present.  Got'r done.  (well, keel assembly still has to be redone, but that is easy).  The pivot point to rotate the bulkheads was easy after all - the reference point I used to locate the bulkheads originally was the step up from the deck to the quarterdeck, so the pivot used was the deck so this alignment remained.
 
The plans overlayed with the Hannah sure look a lot more alike.

Finally, transferred to the building board.  I had to take off and reset the locating blocks but that was no big deal.

Some frames show a bit off because of some drawing issues, I was in a bit of a hurry to get this done.

Come on In Eamonn - the water's fine!  I don't know about that 'league' comment - given the number of missteps and do overs I have done HaHa.  I came out of the initial draw up phase pretty confident I had knocked it out of the park - boy that is funny.  Here's hoping that when I do the full POB the same voyage of discovery won't be retaken LOL.  When you do a Frankenstein build though, no one can 'really' criticize you since you are doing a what if.  Well, they can criticize but you don't have to listen!
 
Thanks for the kind comments, I will buy you a beverage of your choice should ever we meet.  -Mark

Will take you up on that drink if we are even in each others neck of the woods !

Brilliant Stuff Mark .. As Usual !!   I do like your builds..
 
Love what you are doing with the available plans.. Sure are giving me food for though as there is a local boat (Arklow Yawl) I was thinking about modelling but there are no plans,  there was a full size reconstruction about 30 years ago (since broken up) but I never cared for the shape (Topsides too high out of the water).. I may be able to locate those plans and adapt them to photos of the actual vessels from C 1900's.. have a few regular builds to do first though as my skills wouldn't be in your league !
 
All The Very Best..
