After both sides were repaired with new wood and new frames inside it was decide to start with the stern.
During the first inspection the stern did not showed the actual condition where it was really in.
During the summer months and during the repairs of the aft side it showed that most of the inside wood of the stern was rotten away and not only on the corners where the sides do meet the stern.
Going over several web sides it shows that this is a common fact in most of the Storebro 34 built most likely due to the construction and the way water runs of the ship.
Therefore the choice was made to use a band type sander which needs to be moved in the length of the planks in this case horizontal.
After the sanding a thin layer of epoxy was placed over the wood to protect the wood against the nature of the coming winter.
