Yes it's normal.
will cost you a lot more than you're probably expecting. There's a whole deck
, rig, [and all the running rigging
, and the winches, windlass
, anchor] and interior
fitout to do. You will need the plans, and the knowledge to check whether the hull was reinforced where it needs to be to accept the rig loads. It's a huge project, and will take $$$$$ all the way along.
Not knowing how much of a DIYer you are, I won't recommend against it as a building and fulfilling project, but it ain't gonna be cheap
. You will probably spend more than buying
an already built 50 ft. production boat, but what you would have might last longer, and depending on your skill level (be honest with yourself here) possibly be prettier.
As an additional caveat, I'll add that not everybody who builds a boat likes to sail them.
You might be better off to buy a trailer sailer or a pocket cruiser
and go sailing!
Beware of your own dreams, they can lead you far astray.
