Wow, that is very exciting!
And you're certainly going about it the right way, having taken a substantial "shakedown" cruise off-shore to and through the Caribb. You know your boat, you know what modifications she needs, you've allotted time to make them. Sounds like a good plan.
And, perhaps more importantly, you've got a fully vested wife!
Cheers to a successful circumnavigation.
Good to hear from you. I hope all continues well with your big plan. Any updates? And, Happy New Year!
