Arno Twigt kindly made contact with information about Aline IV.  Arno has owned her for the last 20 years and has her original designs, old logbooks, and he kindly provided the photos below.  Aline IV was designed in 1913 and was launched in 1919 following the end of the Great War.  Arno plans to sail her in the Cowes British Classic Week, in July 2015.
