With respect to Dr. Hedenstierna-Jonson's comment concerning sails; it is unnecessary to duck wool, as the fibers swell when wet. This means a thin wool sail will catch more wind while allowing excess water to blow out. This is why wool sails work better than a heavy linen twill. You have no need to continually re-apply tar regularly to better catch the wind.

Is it possible ( and or ) is their evidence of a hereditary practice of passing on the sails due to their high value, to son, clan, or family?
It's too bad there are no subtitles for the Estonian speakers, their presentations seem very interesting judging by the images they are showing
