What type of rig of the launch ? (Help with terminology)

[greenstone]

Gentlemen, I wish you all the best.

Help clarify the correct term - what is the name of this type of rig of a launch in the photos I have given?

 

In Russian documents of the mid-19th century it was written that "rigged as the Plymouth`s boat".

But this name rather has a local meaning for Russia.

This question is important in order to understand what name in English to indicate on the box of the new kit of "MasterKorabel".

Will it be correct if I write as "42ft launch rigged gaff ketch" or "42ft launch rigged yawl"?

Technically it is a ketch as the rudder is behind the mizzen mast.  However back in the day rig names were not as clearly definded as they are today.  That said I think either term could be used.
