Here are images of where the cabin joins the top plate. The cabin fits right into the flat previously occupied by the aluminum windshield frame, so the new cabin/top is truly a direct replacement.
The cabin was positioned to maintain a constant distance from the edge of the top plate on the exterior and this left a small interior gap of varying width. A 1/2" varnished teak quarter round molding will cover the gap. (The dangling wires will be secured when the engine wiring harness is installed.)
Here is the view more towards the bow. To soften the lines and to add a horizontal component, a varnished teak band is going to to cover this junction. I really like a touch of wood and am willing to pay the maintenance price. The teak will be installed for easy removal later. I'm at varnish coat number 5 and still going. Someone in one of the other threads said "There is no scrap teak." How true!!!
The engine wiring harness was short by 2 feet, so a new one had to be ordered, pushing the splash date back a week. That gave me an excuse to do some things that weren't essential for launch, but needed doing anyway. I installed the QL trim tabs (more on that later), placed headliner and teak trim in the forward cabin, installed the magic box (Garmin 740 that does it all), and finished wiring the electrical system. It's always a rush, and a little scary, the first time one powers up the elecrical system. Thankfully, there were no fireworks.
