Are there any yards or marinas in Hawaii where you can leave a
sailboat (50 ft, 42K pounds) hauled out in storage for maybe 5-6
months a year?

It might be possible; there are several yards that can handle you
boat. However, dry storage is very limited here and the yards
discourage long term storage and prices are very high. If you'd like
to research it a bit I have a list of phone numbers for the local
yards floating around in my boat somewhere and I'll dig it out and
post it if you really want it.
