The visibility at sea is extremely limited, and GPS and radar are two commonly used means of positioning.
Relatively speaking, radar costs much more than GPS equipment and is also simpler to use; pirates generally prefer to use GPS for navigation—
as well as relying on the naked eye.
But this has led to many jokes, as Somali pirates have historically mistaken warships for merchant ships and attacked them repeatedly.
Wakanda's escort ships couldn't fire directly at Mei Country's navy, nor could they defeat them, so the only viable plan was to maximize the combat effectiveness of Frank's elite team, making leapfrog tactics the only choice.
They would need several speedboats to transport them near the enemy ships, but they would also need many decoys to confuse the judgment of the naval ships.
Those decoys were lost pirates!
