Nc for this as it could be outing
My parents did just this. All of us kids had moved out a long time ago and my mum's job where she lived had come to a natural end, my dad was commuting 1.5hrs each day.
Their 3 bed house was too big for 2 of them despite having lived there for 25+ years.
Due to things that happened in the past and where they lived they couldn't afford a house nearer to where my dad worked. So they started looking at canal boats.
In the end they sold the house and moved to rented for 6 months while they got a brand new wide beam built to their spec.
As you can imagine they massively down sized. Alot of stuff was brought to mine and other family members houses and they took on board what they could.
They have got through the winter and recent storms with no major dramas.
Due to rules on the canal they ended up with a permanent mooring but the canal community is amazing and their boat is beautiful and about the same size as a 1 bed flat.
We have done a few journeys and it's great fun and sitting on the boat with the gentle rock makes me very sleepy haha
They have intentions to go on long journeys up canals they can fit down.
Also have another relative who lived on a narrow for about 10 years and recently upgraded to a wide beam and they love it.
Obviously you have to consider waste disposal,water and fuel but once you get a rhythm it's all good.
Obviously you don't have a mailbox so if you know someone you can be registered at their property for or you can get a po box.
They don't regret the move despite teething problems and intend to live on the boat for as long as physically possible.
It's a very different way of living and you do need to make adjustments but it's a good adventure
