Best Answer - Chosen by Asker:

Because the depth of water there was too shallow for the torpedo as such!. By using wood, around the tail of the weapon, leaving the propellor clear, the torpedo 'evened out' much quicker and navigated the shallow water to their targets!. Very clever and very deadly!.Www@QuestionHome@Com

I'll doublecheck after I post, but I thought they made wooden fins for the torpedo tail, to make them run straighter after being dropped into the water by plane!.

** edit **

I was close!. They were wooden fins to compensate for the shallow depth of the harbor!. Normal aerial torpedos went to nearly 100 feet, while Pearl was around 45 feet in general!.
