Two cats in the yard, life used to be so hard

Actually four cats in the marina, but everything reminds me of song lyrics lately...
"Thunder and lightning, very, very frightening"
"Hotel California, mirrors on the ceiling, pink champagne on ice"
"It's raining, it's pouring"
"Our house is a very, very fine house"
Ok, where was I going with this?
Oh yeah, there are four catamarans currently parked in Marina de La Paz.
One doesn't fit.



Hmmmmmm....
Which one is it?
