Size isn't necessary, per se. But in some cases, larger size makes room for equipment or storage that gives you more options in how you can use the boat. Such as ability to carry more clothing, more food (especially refrigerated / frozen items), more fuel, space for a watermaker, etc. Those things aren't necessarily required to travel and enjoy the boat, but they do open up more options and allow travel to more remote places.
As an example, on the trip we just took, only 1 place we stayed had shower facilities available on land, so being able to shower on the boat was a big benefit. Having decent size batteries and a generator meant that not having shore power wasn't a big deal, as the only thing we couldn't do was run the A/C overnight (which wasn't really necessary anyway). If we hadn't had some of those abilities, we could have still taken the trip, but we likely would have had to choose our stopping points based on available facilities (and likely would have ended up paying for dockage), rather than being able to stop wherever we saw a nice town dock.
To an extent, this is all what drives me liking simple large boats. I like the idea of a larger boat that's basically just bigger, but not more complex. Unfortunately, most get much more complex as they get larger in the search for ultimate comfort or fanciness. Sometimes the nice things just come along for free in the design, however. Like the king size aft bunk on my boat. The bunk is really a fuel tank enclosure with a mattress on top, so with the desired size of fuel tanks, it ended up being a king.
There may be organizations similar to this one out there who are on the up and up, but personally I would steer clear of this one!
