Ever notice how many people keep buying different boats? IMO that happens if you don't really understand what you need in order to what you want.
Buying a live aboard ocean cruiser doesn't make sense if your next ten years will be weekending on a lake.
Makers sell boats by length but you live in the interior volume. Bow pulpits and swim platforms added into the length help the marketers and perhaps add to bragging rights at the club but do not improve interior space.
I emphasize interior space because if you will be aboard for a long time the weather may not always be comfortable outside.
