Bene, as I understand it the lightning rod does not "grab" static from the sky, but rather it allows the GROUND CHARGE to bleed off UP into the sky. When there is a trike, normally the ground charge goes UP creating a path of ionized air, and then the cloud strike comes DOWN that same (more of less) path, creating the damage.

A pointed rod apparently can discharge ions better than a rounded or blunt rod, which is why some makers were using "bottle brush" designs with many fine wires at the tip, since each fine pointed wire end allows another point where ions can bleed off.

If someone on a sailboat had a blunt lightning rod--it wasn't for performance reasons.
