Dimi,
I think your explanation about TWL is not correct - not one of the existing boats are measured like this (esse 850: https://www.swissratingsystem.org/app/srs/srs2012.nsf/SrsBatPag.xsp?action=openDocument&documentId=00002A32&mod=dsp ... do they have no bowsprit?)
The bowsprit is only important if it used for upwind sails.
I think this is an error of the translation from french to german.
