Dear Badger (WI?) -
Can't really say that anyone is THE expert - a bunch of us have done it more than a few times. Not much to it really, it weighs 600 lbs so you probably need a marina crane. Pull it straight up - AND have 5 or 6 putty knives handy so the board does not hang up on the trim as it comes out (you'll see what I mean when you do it).
Just be sure to go VERY SLOWLY as the board nears the top of the trunk, and tab the trim behind the delrin (sp?) bushings on the sides & front/back of the board. Don't lose those, or change their position - they are what makes the board seat properly in the trunk. If they are out of position, the board can be difficult to raise/lower.
Last time I had mine out i hung it from a chain fall to work on it - very handy to spin, tilt, lay it down, etc..

Hope this helps, PAX & Fair Winds, Skip Oliver
