I just found this article my dad wrote with some pretty good photos of Puff. I think that's me on deck in the middle below the sail if you squint real hard. That top photo is circa 1982??

What an amazing boat! It looks like a Wharram (and your dad says in the article he was influenced by Wharram's designs). James Wharram was one of the original Mustachians--he designed simple plywood catamarans, influenced by Polynesian outriggers, that could (and did) sail around the world. He thumbed his nose at the yachting establishment and proved that you didn't need a lot of money to have a boat that could cross oceans. He wrote a few Mustachian books, including "Two girls, two catamarans", about crossing the Atlantic. He's still actively designing boats today.
A few other posters have asked about cruising. First, keep in mind that living on a boat can be very inexpensive, even if you don't go anywhere! In the San Francisco Bay area, every once in a while an old, wooden Chris Craft of 40-feet length or so and inoperable engines changes hands for under $10k. These boats are basically inexpensive apartments on the water. I'm sure a few buyers intend to restore the boats, but most are just looking for a cheap place to live in an area of outrageous housing. If you go this route, an old fiberglass cruiser or trawler is probably your best bet. Make sure that you're buying a boat in an approved liveaboard slip. These slips are becoming rarer in the U.S. as they get squeezed out by waterfront development and anti-Mustachian weekend boaters in expensive megayachts who don't approve of the neighbors.
Another thing to remember is that while many people dream about sailing around the world, most don't actually do it, and there's nothing wrong with that. Near Seattle, it's possible to cruise for years--even most of the way to Alaska--and barely "set foot" in the ocean. The same is true for the east coast. Many retired powerboaters do the "Great Circle": Intra-Coastal Waterway down the eastern seaboard, across the gulf to the Mississippi, then up to the great lakes and across to Canada or New York. (Yes, the entire eastern half of the U.S. is kind of an island). Why wait until you're 65? Nobody is born knowing how to get a boat across the Gulf Stream, or how to read clouds and know it's going to rain. Every experienced boater starts somewhere. There are actually a lot of free or almost free boats available. Many sailboats in the 20- to 28-foot range are abandoned in marinas, and the marina eventually gets a lien on unpaid moorage and auctions the boats for a pittance. They usually need a lot of work but they float. So buy one of them, learn to sail (or learn whether you actually like sailing), and sell and move up. The other Mustachian advantage of starting small is that you learn the real costs of boating--maintenance, moorage, etc., and you can determine in advance whether the bigger boat really fits your budget and lifestyle.
While 95% of boats and boaters are about as Mustachian as a Porsche Cayenne, it doesn't have to be that way. Look for community boating in your area--if you're anywhere near a body of water, chances are you can get out on it for cheap, and you can bring your kids. You can learn to sail for free or nearly free through many of these programs. Sailing is great for kids--how many other vehicles can a 6-year-old drive themselves? My daughter (6) can steer my 32-foot sailboat (which I built myself--a lot cheaper than store-bought). Last weekend my family rowed around on Lake Union in a classic wooden rowboat. My son was the captain/pirate, my daughter was the navigator/bird spotter, and it cost us all of $17.
