I Love microskiff.com!
Hilarious, and true. I'm sure he's missing a few. What else would you add?
REASONABLE ABILITY TO MAINTAIN BALANCEGreat job by Huge Flyfisherman. He covered the most disruptive things people do on skiffs. My personal worst is bringing your entire fly fishing collection stuffed in a giant gear bag.
I generally do not launch a skiff until the friends/clients arrive. This goes a long way towards minimizing gear transfer accidents and gives me time to advise and ask what they are thinking about loading into the assigned one hatch space. The best clients just show up with suitable clothing, a good attitude, reasonable ability to maintain balance, and decent fly casting/line management skill. No gear needed.
