Culé ou Barco de água Acima
 
I got the plans for this boat at the Museu de Marinha in Lisbon when our cruise ship made an all-too-brief stop there. The museum is incredible.

 
Barco de água Acima roughly translates to "boat of the upper river".   It is designed to transport cargo from the shallow upper reaches of the Tagus River and via canals.

The cruise was in 2005.  I started work on the boat's tender in 2006.  As you have already surmised, there have been long periods of inactivity...

The boat's tender is called a chata, which directly translated means 'flat', but in this context it means a flat-bottomed boat.

 
I think the chata reached it's current nearly-complete state a couple of years later.  I did not start on the main vessel until December 2012.  The picture below shows it when it was cut away from the building jig just a couple of weeks ago. There are two more rows of planking above the wale that have not yet been added.

 
The big challenge with both the boat and its tender is that they are carvel planked but with no keel.  So I had to come up with my own building jig.  I've since seen some similar approaches, but not until after I had derived my own.
 
When time permits, I'll add some more posts showing the progress from the beginning.  Also, you can see my page on our club website:

Thanks to you both.  If you can cite any references, I would appreciate that info too.

To be clear, we are talking about both treenails and spikes in the same joint, not in different locations of the ship (all treenails here, all spikes there).

Why use both in one joint?  Perhaps the spikes give some immediate grip before the treenails have had a chance to swell?

The drawings from which I am building my model do not include fastener details.  So I am using a book on another type of vessel that, though not very similar in appearance, does share some key characteristics.  I have a question about how to interpret a drawing from that book.

The question is whether a detail for connecting frame timbers using treenails is
1) only treenails or
2) a combination of treenails and spikes

The drawing and more details on the question can be found on a page for our club site. 

Opinions will be gratefully received.

Thank you,

Greg

I've found the link with the anchor does not always work.  If it does not go directly to the section on fasteners:

1) go to http://www.hrsms.org/home/Cule+and+Chata
2) Click on the tab for Research
3) Scroll down to nearly the end of the page, where you will see a heading for fasteners
