Managed to finally get the water tank to fit on Friday after cutting away some insulation from under the well deck and using the lowest profile 1/2" fitting I could find for the breather pipe:

Also got a final coat of paint in boatman's cabin including behind weed hatch. Saturday was spent putting coat of grey floor paint on bilges and floor of boatman's cabin:

Then continued with insulation and battens on the cabin sides creating a lot of mess in the process!

By the end of the weekend and with a good tidy up it was looking much better. Insulation and battening was completed on the cabin sides (and insulation only on the roof) from the front back as far as the side hatch including insulating under the gunwales. All exposed metal has been covered - 25mm celotex used and 3mm foam used on any exposed steel angle/box etc. then all joints and 3mm foam covered in foil tape (still some tape left to put on) to provide a complete vapour barrier. Hopefully that lot will keep condensation at bay!

Only got 1 week back at work then a week off so hopefully next update will show quite a bit of progress!
