Hi Mike,
There's some vertical polarization off the ends of an inverted-V,
but is significantly down from the horizontally polarized radiation
broadside to the antenna. The advantages of a seaside location
for horizontal polarization are an unobstructed horizon and very
efficient ground gain from an extremely flat Fresnel zone. Many
carefully selected land locations can provide the same benefits.
Unless you can install your inverted-V sufficiently high to produce
significant low angle radiation, you would would do much better with
a vertical very close to the sea shore or a salt marsh.
Installing your inverted-V near the edge of a bluff overlooking the sea
would also be excellent if its sufficiently close to the edge so that the
inverted-V illuminates most of the near edge of the Fresnel zone.
Of course, many land locations can provide the same benefits.
The benefits of a flat Fresnel zone are discussed in detail in:

Subject: Re: Topband: verticals by the sea
Is there any advantage to using an inverted VEE by the sea? Didn't I read
inverted VEEs had a lot of vertical polarization?
Reason I ask is I plan to do the IOTA contest on an Island in NB or NS and
have not yet decided on an antenna.
Thanks,
