STEMPOST, APRON AND STEMSON

The stempost (ášta) and the apron (kóntra ášta) were the most arduous to fabricate among all of the construction parts. Thanks to modern computer technologies of designing and plan transferring many problems were avoided. There are known many cases in traditional boatbuilding, where the construction parts did not fit together, so that the boat builders were forced to intervene with a more drastic measures requiring to reshape the parts. The pictures below show the main milestones in our fabrication of the abovementioned parts.

The planing is followed by the transfer of lines from the boat plan with carbonless copy paper.
