I say go for it! I'm, too, am in my 40s (and my husband in his 60s). We are going to be moving back on board our Passport 40 at the end of the year - with our two young children
. We moved back on land when I was pregnant with our son back in 2010 and have been yearning to get back to life on the water since.
That being said, keep in mind that you will have LOTS to do to prep yourself and your family
for getting ready to sail. I started out by taking a live-aboard sailing course in Ft. Lauderdale, FL (Blue Water Sailing School - Sailing Lessons, Sailing Courses, ASA Bareboat Charter Certifications
) over 10 years ago.
Other things you'll need to research
besides the obvious boat that will take you where you want to go safely and still be comfortable: a source of income
, where you might want to go (live-aboard slips aren't available everywhere and some places don't allow you to anchor
out), how dependent you want to be on electronics
, homeschooling for the kids (we will be using Calvert Homepage
).... I could go on and on, but the things listed will be a good place to begin. It takes a lot of work and planning, but I wouldn't change the decision I made 10+ years ago to do what you are wanting to now
