I am sure someone will provide a more detailed and technical answer, but
the short answer is VHF and UHF signals are line of sight, and repeaters
are usually situated with high antennas to give them plenty of that...
So how high above the sea will you be? From an airplane, you can "see"
typically 100 miles or more (all depending on altitude of course); and
from the space shuttle? Even more; and they do not use much power to
make their contacts when running ham radio.
But there is not much blocking it, and sometimes you get ducting.
So I think the answer is to what purpose? If you are just playing, it
might be boring; if in a life raft, it might be useless, but a low power
emergency beacon would work. You could get a lot of action signing
maritime mobile though, even with a QRP rig...
I would recommend taking it and playing, but taking other radios as
well. (but I tend to consider myself a pack mule and bring everything I
can to assure fun).
If you are really interested, you might join the HFPack group, and pose
the question "I am going to be at sea on this sort of boat <insert craft
type, length, and so on> at sea on a journey from <x> to <y>; what would
be the ideal portable set up to bring along?"
I expect you would get a lot of answers; I am positive I would bring my
K2 along; too much fun to leave behind! And the ocean provides such a
nice ground; an insulated back stay, or a vertical, and you are in
business to to speak.
