Hello G, A and little A and welcome to the forum.
This place is a fantastic resource for
learning. I think 99% of the questions you think up will have been discussed here at some time. Go back through some of the previous posts and you will find discussions on different boats, costs to own a
boat, cost to
cruise, different
destination, engines,
sails,
plumbing,
electrical and anything else to do with boats.
I do recommend caution. The sailing life can be quite addictive. One taste and some are hooked for life.
