I weigh 225lbs so I am thinking I am a little big for the adventure.
Not at all! As you can see in the blue Adventure, you're not anywhere near my friend's size (he's not pushing the Adventure's capacity either). He traded the Outback for the Adventure for speed and loves it. It has the additional advantage of being about 1" longer to the pedals (significant if you're tall) and wider in the foot area than any of the other convention Hobie singles.
After trying out his boat, his petite wife upgraded to the Adventure as well, so she could better keep up when they cruised together.
In a fast cruise, the Adventure runs about .3 MPH faster than the Revo. That may not be big to some, but over distance, it adds up.
Unquestionably, the quietest and smoothest running Hobie, the Adventure really distances itself from the rest of the fleet in heavier wind and chop. It pretty much cleaves the chop and its small frontal profile defies the wind.
But, as has been noted, the Revo has its advantages as well and is an excellent all around boat. You really can't make a bad choice here.
