Welcome and congratulations on your marriage.
Your plans are certainly ambitious and I wish you well on whatever you decide to do.
However, if you are new to sailing, and new to this boat, you may want to consider getting used to sailing her as often as you can a little closer to home and get your handling, anchoring
and M.O.B drills etc. up to a high standard before you venture further afield.
That will also teach you something about how to fix things that go wrong when you're out at sea and what collection of spares and repair stuff you will need which is kind of important when things do go wrong. (As they do)
Having explored the North Sea coasts, perhaps the Canaries
or the Med or, if your confidence in both you and your boat is high, head off, either solo, or better yet, as part of a group to the Azores
and onto sunnier climes. Finding other boats to cross the pond along with you is usually quite easy and being part of a group provides a great security
I'm not trying to dampen your spirits or diminish your ambitions, I'm just adding my two cents for what it's worth. Safe sailing to you, James
