The rotomoldeds have all the right features for popularity except extra speed and agility. The Wave is a 14-footer that is about right (and I assume this is why Rick and Mary like it), but its speed is limited. The Getaway is a fun boat, but not agile enough.

What is missing is something is the middle category between the fun, beach cats and the performance cats. (The H16 is a performance cat IMO.)
