MASB 32
Second World War 63ft MASB which has been shipped from the med to Lowestoft for us to work on.

Here is a picture of the vessel prior to being lifted into the water for the short journey to our yard
Now in the shed
having now been slipped and washed off MASB 32 is hauled into the workshop where she will undergo work on the hull planking.
Plank removal
Port side undergoing the same treatment, outer planking being removed to reveal damaged second layer.
Repairs
Here we can see the damaged caused when the boat was lifted, the chine having been broken behind the planking along with frames.
Starboard side repairs
another shot of the extent of plank removal required to gain access to the damaged chine, not only has the outer planking above got to be removed but the inner planking has to be released.
Then the planking below the chine has to be released so that the chine timber can be removed.
For obvious reasons the chine timber can not be removed from inside the vessel as all the frames are fitted over it.
Starboard side repairs
The plank removal will also mean that the planks will be cut back to a point where the staggers in the butts is such that they meet required standards of construction. These boats rely on long planks over lapping each other with any joins and or scarf joints not appearing close to each other as this creates a week point which will eventually cause hull failure.
Starboard side repairs
In this picture you can see the damage caused to the frame below the chine, this frame runs down to the keel and now needs removing.
Starboard side repairs
This photograph shows now that the planks have been released the chine timber can be removed, the shape if this timber is clearly shown and is the reason why some much has to be done to get it out.
Starboard side repairs
Now we extend our efforts to the area below the chine rail where the planking was also damaged.
Materials
Just the matter of a little mahogany for the repairs, all cut to 3/4" boards and supplied by J. B. Timber of North Cave, East Yorkshire, and very nice timber it is.
port side repairs
Now the inner planking is being replaced with the new mahogany planking and initially screwed to the frames whilst awaiting the outer skin.
Starboard side repairs
Plywood gussets being replaced where the frames were replaced, these hold the two separate frames together, those below the chine and those above, they are also drilled out as per the original spec to save weight and increase strength.
inner planking being replaced, initially this is screwed to the frames but will obviously be copper nailed to the outer skin when this is applied.
Calico covering
here you can see that the calico cloth has been overlaid the inner planking which is now completed. Once the cloth is tacked in place it is covered with linseed oil and varnish mix which firstly makes it see through and most importantly waterproof.
port side repairs
in this picture you can see the pencil lines drawn onto the outer blanking show us where the frames and diagonal timbers are. At present the planking is screwed to these, the area between frames and diagonals is where copper nails need to go. This stops the planking from curling or "cupping" away from each other and also makes this construction a totally riveted structure.
MASB 32
Starboard side nearing completion, all planks at present are screwed to the frames and diagonals. Following on from this we will be completing the fastening by copper nailing between frames so that each plank is nailed and roved to each other.
MASB 32
Now the job of nailing or "riveting" the planks together, each copper nail has a rove fitted on the in side of the hull, the nail is then cut to length and using a ball pein hammer the nail is peined over. This makes a riveted joint which will take some movement with out coming loose or falling out.
