Fuel the dream?
The boat show is good, in that you can see a lot of boats in a short time.
Crawl around, lie in the beds, start that list of general things you think you'd like, and NOT like, did I say lie in the beds?
Can people move around the working spaces well, or is it a one person job to cook and set the table?
Lots of boats lets you compare living spaces, space utilization, practicality vs glitzy...
Bags full of sources of supply, resources, boat clubs, catalogues, sales brochures...
Take you camera so you can remind yourself later.
