True --- but I would go with the omni directional anyway, for the same
reasons that you mentioned.

Sea action will move the antenna about in the xy plane as well as up and
down. There is more than simple up and down bobbing going on here.
There would be no guarantee that the forward lobe of a directional
antenna would be pointing towards the receiving antenna.
