There is a hook system that allows for this.  However, that system may be seen as impractical for a couple of reasons.  Both passengers cannot board the plane simultaneously.  It's required to open the canopy on one side, board a passenger, close the canopy, open on the other side, board the second passenger and then close the canopy.  Another aspect I considered is that if not perfectly made, the hook system may fail during flight.  I read a few accounts of pilot loosing their canopy in flight... this may not be so much fun...  I also believe that a forward opening canopy would be much nice than a side opening one.

I decided to go for the Zodiac XL canopy installation.

I debated purchasing the canopy kit from ZAC for a while.  I got the information from Nick and Sebastian and found the part prices to be acceptable, but I could not deal with the crating and shipping cost so easily.  Therefore, I decided to make this from plans like I did for the rest of the project.
