Reloading A Torp On A Pt Boat?

Im trying to play around here and shoot more than the 4 torp that are on the pt boat rack.. In the inventory it shows that the pt has a max number of 12 torp. Now is there a way to relaod a torp onto a pt boat?

it only works on the LFN and IGN PTs, the american one doesn't seem to reload after u fire the four

Well you only get 4 torps on a PT boat, maybe you can reload when you ask a oiler or a marchant to reload you. To do soo you need the lattest patch. I think the caracteristique of the pt boats are wrong, you get 4 torps and that's all.
