It looks like oversized mooring buoys to me.

Absolutely! :-)

It probably is my/your sweet tooth...

Not bad. You even place an ancient Greek trading ship beside the medieval ship.
 :-D

But seriously now: since eons I try to find someone who's good in ship hull
development in POV-Ray. I am in maritime archaeology since over 25 years, and
would like to start a cooperation with someone to make all my reconstructions of
ancient Roman and Byzantine ships three-dimensional. Interested?

I've attached one of my reconstructions (one of the dreadnoughts of the ancient
Egyptian fleet of Cleopatra during the sea battle of Actium). Each of them would
make amazing 3D models...

I know, and I have commented to you before about this. The best way to 
go, if from scratch, is to use one of the (commercial) nautical 
programs. The one I use is the free version of DelftShip 
http://www.delftship.net/ with which a hull is relatively easy to build. 
To do this correctly however, one needs measurements data about the ship 
over longitudinal sections and above all cross-sections, or better 
cross-section data, which can be put in a spreadsheet and imported into 
the program. This gives a rough hull which has then to be improved both 
in DelftShip as in any available modeller. And finally comes all the 
work needed to build the remainder of the ship...

As far as I am concerned, I would be interested, where it not that time 
is an issue. Already the TC-RTC Challenges and my own projects fill my 
days and, as you can see, ship or city building takes many months.

However, if you can provide me with a spreadsheet of raw data about a 
ship, I can see what I can possibly do. By raw data I mean the overall 
length, width and depth of the hull of course, but also several (at 
least 5 or 6) cross-section measurements across the hull (at least a 
dozen height vs width measures from the origin) and one centered 
longitudinal cross-section measurements (at least a dozen height vs 
length measures).

Taking the back-end of the ship as origin, the format would be in three 
columns: Length data | Width data | Height data

Example for a cross-section at origin:
0.00 | 0.00 | 0.00
0.00 | 0.25 | 0.50
0.00 | 0.50 | 1.00
0.00 | 0.80 | 1.50
etc

Example for a cross-section at 5 m from origin:
5.00 | 0.00 | 0.00
5.00 | 0.30 | 0.50
5.00 | 0.90 | 1.00
5.00 | 1.50 | 1.50
etc

Of course, the ancient did not publish ship plans ;-) so these sections 
would have first to be drawn by hand or in a program like Inkscape and 
then measured manually...

FWIW For one side project I work together with the game development 
group at the Amsterdam University of Applied Sciences. We have students 
of the game development course in the Anatomy/Embryology department of 
our hospital that make 3D models of the various organ systems during 
embryological development. That cooperation works very well.
Perhaps you also have a game development course in the CS department of 
a university nearby. Some of these guys (or girls?) would love making 
such 3D models as an intern.

I think that is an excellent suggestion indeed.

Out of sheer curiosity: What are the /real/ dimensions of this ship? Not 
according to the human figures on board surely. If I take those as basis 
(1.80m height), the ship length would be about 59m; the mast height from 
the deck about 42m; the underwater ship height down from the water line 
about 9m. This cannot be right. Also, the form of the underwater ship 
does not seem to be according to the proportions of antiquity. The keel 
should be much shallower and with a rounded prow?

My guess is that the ship should be between one third and one half of 
these dimensions.
