The first task once buying the boat was to get the 12v electrics, 240v electrics, cooking, hot and cold water working. Its so much easier to work on the boat when your warm and well fed.
Well, actually first off get some 12v power to the main switch panel, get the cold water pump to work, sterilise the cold water system and sort out shore power.
Sort out the gas supply, replace the 4.5Kg bottles with 7Kg, fit multiple C0 monitors, fit smoke detectors and get the gas monitor to work.
Discover the cooker just works.... Yay lol
Lesson number 1 with boats..... there is always another job to be done.
Also discover the hot water pump does not.
Get the heating working.
Work out some of the reasons why the taps work intermittently.
Chase down some wiring faults.
Its not a glamorous task but it needs to be done.
Time to do the initial upgrade of the fresh water system. Add a strainer, a filter and a one way valve.
