Several times, over the past few days, I have observed something that has contributed greatly to the destruction of carrier task forces, and it results from the behavior of friendlies. Friendly PT Boats to be specific. How? I'll show you.
Since the release of 1.10, and the elimination of the "laser guided" bombs (error free bombsight), the primary method of attacking carriers is now using low-flying torpedo carrying bombers such as the Ju 88 and Ki-67. Typically, these aircraft approach the CV group at between 100 and 200 feet in formations of three. Normally, these are easy kills for the 5" guns of the carrier and cruiser. I say normally, because if a PT gets between the guns and the enemy aircraft, the proximity shells are detonated by the PT. Last night, I saw this happen again and again, with enemy bombers getting within 2k of the carrier, unmolested. Their torpedos eventually sank both ships, all because some noodlehead parked his useless PT between the CV and the enemy airfield. There were other contributions, such as sailing the force directly at the enemy field, thereby masking half of the defensive guns. However, PTs were the biggest factor in allowing enemy torpedo carrying bombers getting in close.
Personally, I don't see any reason to have PTs anywhere near the task force. Their contribution to the tripleA is minimal. Likewise, I find PTs to be the most useless vehicle in the game. I kill them by the dozens, and rarely get hit in return. Hell, I killed 3 with a potbellied FM-2, with its 4 little MGs. When the CV is sunk, it seems that half of the pilots spawn PTs. Why? Basically, they are defenseless against determined air attack. I'll orbit the spawn point and kill half a dozen in 2 minutes with a C-hog. Yet, these PT guys keep respawning. I can only conclude that their parents let them play with hammers as children.
Powerboaters, don't motor your scows in between enemy airfields and the CV group, you become a liability to the task force if you do. If you must play with toy boats, save it for the bathtub.

As it is, you are only helping the enemy kill the task force.
