I'll be moving around for the next few years and will not often know
where I'll be more than three months in advance. The obvious thing to me
seems to be to live on a boat and take it with me. Unfortunately, I know
very little about boats so I have accumulated a few questions during the
past few days of googling:

What's the difference between a motor cruiser and a cabin cruiser?

Can I find a boat that's small enough to fit in a canal yet big enough
to live on and sea-worthy enough to cross the channel in?

How easy is it to move between canals, rivers and coasts?

If a canal is x metres wide does my boat have to be x/2 metres wide so I
can pass others?

Does 'Dutch' mean something special?

How much training do I need to drive a boat inland?

How about offshore?

Would a serious sailor never consider going to sea in a boat with only
one engine (and no sail)?

Can I get out-riggers or attachable keels or something to make a canal
boat seaworthy?

Are there many places not within commuting distance of rivers or coasts?
