Well we are in the exact same position. Except our kids are 3.5yrs and 14 month old girls.
I think a lot just depends on personality and how adaptable you are. Kids will adapt as well as thier parents do. If its not an issue for you it will be less likely an issue for them.
Having said that this is not really about surviving but rather living a life style that will have some comfort.
was not a huge issue for us we could get by easy on a 38 that we have our eye on. There have been a few 35-36 footers we could get by on easily too. They of course are the same price
as the much nicer 38 we like.
However this will prolong our leap and we want to start lioving now. Our 28 footer will be on the market very soon and if it sells fairly quickly......we will buy a N 31 thats circumnavigated and is set up ready to go or if that sold something simular.
That is all thats in our current
budget and it wont be easy but we feel with some mods we can do it on a descent 31. It will be tight and we will most likely step up in size once the girls are reaching thier teens. By then we will be able to buy the next boat and sell the 31 for a kitty fund. Thats the plan anyway.
BTW this has been a 12 year plan getting us here and everthing we have set out to do has gone ahead. We currently rent a very small one bedroom while we finish selling all our stuff and we find less is more.
So if I was you and looking at one yacht for 4 until college with 2 boys. I would say 35-38 would be about the smallest and still comfortable in the right design and layout of yacht.
What we found looking was that its more about layout and design then just length. Often the layout seems to be just more of the same as they get larger until the yacht is very big. We dont need a bigger head
and a bigger table galley
stc what we need is a layout thats suited to 4 long term. Now personally since thats just out of reach for us we will take an additional step and move aboard a smaller vessel first until we out grow it.
Hope this helps in some way
