Finally bit the bullet and started to take the top planks off the hull and dismantle the inside to gain access to the hull to repair and replace the rotten and damaged parts

Cutting off the top plank with a reciprocating saw to get rid of the plank is the best way and then chisel off the parts attached to the ribs and frames  

The aft part of the port plank now removed and it as exposed the rotten and damaged frames and damaged to the beam shelf 

One of the frames which is in need of replacing as it is broken lower down and had a piece let in when it was first fitted in 1939 when it was the wrong shape and fitted a wedge to make up the difference

The top of the frames in a bad way and are both broken lower down. The two that are in the worse condition are the main chain plates and the lower stays on both sides of the hull 

Next job on the forward end of the hull the replacing of the ribs after they are removed and the new ribs are made and steamed into position 

The starboard bunk is now being dismantled
