what stays, what goes?
Considering that you will only have so much space for anything aboard, you will obviously be disposing of 98% of your current home''s contents.
If you think you might be able to use (and prefer to keep, if possible) some things like crystal, a few pieces of art and silver, towels, etc., then just plan to transfer them to the boat. The worst that can happen is you decide later they are not appropriate and you replace them with something that is.
If this is your major remaining dilemma, I congratulate you for being well prepared. Best of luck with the transition.
