What is your preference and why? This seems to be another issue that elicits strong opinions.
We are used to having fresh air through our house. We never have every window closed and sleep with the bedroom window open because it is under our front verandah so the rain can’t reach it. Even on the coldest nights we still have the window open a couple of inches. During milder weather we keep the back door wide open until we go to bed.
This will be something we’ll have to get used to when living in a colder climate. It might be impossible to leave windows or portholes ajar all the time. We love the look of portholes from the outside of the boat but they only open a little bit! So… our preference would be windows.
Since we decided to work towards our narrowboat goal, we’ve wondered how we’ll manage sleeping in a steel box after a warm Summer day. Does it get hot inside? Does it cool down at night? I don’t think I’ve read a single blog entry complaining of being unable to get to sleep because it’s too warm. There’s lots of complaints about cold, rain, snow and condensation though!
