Strakes at stem and stern on clinker built ships

[Dr PS - Paul Schulze]

I am trying to figure out how the strakes on a clinker built ship or boat overlapped (the sud) at the stem and stern.  I find it possible to bend strakes from having sud to not having sud as you approach the stem and stern but I feel this may be incorrect.  If the strakes do overlap at the stem and stern, how are they joined at the stem and stern posts?  Are they beveled or notched in some way?  Is there an article or post on this which I might have missed.  

 

Thanks

Paul,

Answering this quick and dirty:

Good Morning Paul;

 

There was a very clear photograph posted recently by Vladimir Wairoa in his build log for the Cutty Sark model he is building. This shows the run of the stern planking beautifully (this is the stern, note the rudder pintles, must be a whaler; although the bow would be identical in a transom-sterned boat)

 

In conjunction with Jaager's post above, this should make things clear. As well as a rebate, the planks can have a chamfer between them, to a line drawn between the two internal angles. this is easier to construct on a model.

 

All the best,

Thanks Jaager and Mark, I think I am am beginning to see. I will need a chamfer on the upper edge of each strake, near the stern and stem posts, and a rabbet down the keel as well as  the stem and stern posts. Is this correct?

Good Afternoon Paul;

 

Yes, you will need a chamfer on the bottom edge of one strake, and the top edge of the corresponding strake. The amount of overlap stays constant, but the angle of the chamfer changes. It will be approximately vertical where it starts, and around 45 degrees by the time it reaches the stem/stern. The rabbet will be as you describe. 

 

All the best,

Thanks all. I have never tackled a clinker model before and none of what has been said was even hinted at in the instructions.

A good book on building model open boats will also show you how to do this. I find a rolling bevel is easier to do at small scale, especially if the planks are only 1/64" thick! The clinker boat at the back is 4" long.

Very nice work 😎
