Some of that path would be over salt water, although that would not be much of a difference for daytime skywave. But I wonder if the unobstructed skip point might make a difference.
Salt water can make a big difference in groundwave daytime reception. On the south coast of Puerto Rico at the place I had at Rincón, dozens of coastal Venezuelan stations and a few from the Colombian coast were audible all day, every day. 600 to about 800 miles.
I sailed across from FL to PR once, and was able to get WBZ daytime once the coast of FL was left... over a 15 day trip, I listened to WBZ frequently both day and night... of course, during most of the time when we did not need any electrical device turned on, there was zero noise on the band. Oddly, the NYC stations were not audible daytime, but came in moderately well at night. WBZ was, of course, the best listen (1980) as it had marvelous programming then.
