A cold and cloudy Saturday on the Fraiser boat has Albie, 6, restless. There are no other children on the mooring or anywhere close by so he and his younger brother Josh, 4, have to be creative in order to entertain themselves. Luke and Laura have loved living on their narrow boat at Three Mills for the past 6 years but they are out-growing their home and with the inflated housing market in London, they cannot afford to live anywhere else.
