Family Ships Bovo

This is a quick drawing of a

Bovo, similar to the

San Biagio and the San Biagio II

Here is a prime example of my confusion concerning these boats.  I have seen several pictures of boats very like this that are labelled as Bilancelle(Plural)  Then I see a picture of a Tartana, which has one mast with two sails and a bow sprit which is elsewhere described as a Bilancella.  So I encourage you to look at these for entertainment value, and maybe someday I can clarify the issues.  The spar at the back should perhaps have a couple of lines that extend from the end toward the waterline like the bow.
