Ok, I apologize for pointing this out, since you mentioned that you were
not concerned about the flight other than what the ATC procedures were, but
because of a few recent high-profile over-water crashes, I have been
fascinated about the time/distance difference between over-water and
over-land routes, when there is a choice.

Using Jepp's FlightStar and a Bonanza V35 aircraft profile, I quickly
flight-planned two routes, one direct and one over land. I assumed KWEN
(Craven Cty, NC) as a departure and KPBI (Palm Beach, Fla) as the
destination to get a large over-water route.

A direct route from KEWN to KPBI, a total distance of 527 nm, results in
about 400nm over water. Using the Bonanza V35's aircraft profile with a
true airspeed of 175 kts (at 10,000 ft), Jepp calculated the route with a
total time of three hours. Of that three hour route, 2hrs 40 minutes of
that would be over water.

The over-land route remained just over the coast, flying from
KEWN to just northwest of the Brunswick (Georgia) VOR and then to KPBI.
Total distance was 621 nm and total time was 3 hours, 30 minutes.

Difference in time between the two routes? Only 30 minutes. Among all of
the concerns I would have about that particular over-water route would be
the thought of getting stuck on the easterly side of a line of tropical
t-storms and having no land options.

Again, sorry for going against your original post, but I thought the time
difference was interesting enough to post.
