Should be pretty close to the Sedan
I don't recall the exact dimensions, but when i had the boat on the trailer it was just around 13' to the top of the windscreen. I took the screen off and the driver wasn't too worried but we still had to have pace cars, and he took every exit just to avoid problems.
I should point out this was 13' to the ground, not the keel. It was also quite a few years ago and my memory .... well enough said there.
One word of caution -- i was just reading the Trawler Forum and someone trailered a boat which was bow down. The result was the water from the muffler back flowed into the cylinders thru the exhaust valves and caused some severe damage. Ouch
