Gipper, take your dogs with you... But it's more likely you'd be living on a specialized deep sea platform than a cruise ship. Cruise ships need to be dry docked every year or two, as do most ocean going vessels. Deep sea platforms can remain at sea for much longer periods.
Dahermit, you should be a big supporter of seasteading. Just think of all those people you hate and hope to one day guillotine... You could be rid of them without bloodshed. Of course then you couldn't steal everything they own, so maybe that's why you don't like seasteading.
Centrehalf, you should learn more about seasteading. I for one would be happy to stop pulling the wagon of the welfare state and live on the ocean. As for being close to land, you'd have to be at least 200 miles offshore, in international waters, for any hope of political autonomy.
On a side note related to seasteading, I'm a big fan of sailboats and trimarans in particular. I'd like to buy one and live on it... a one man seastead if you will. There are two companies in particular who have very nice options, Corsair and Dragonfly. If anyone is interested, or just bored, check out the links and visit their sites. They both have lots of photos of their different models, complete with interior shots and floorplans.
Corsair F31

Dragonfly 1200

Seriously... You should check out their sites and have a look at the interiors... Amazing.
