Would you be willing to answer a few brief questions about PlayStation Forums?
It might be a little easier to find the number of people you need at ps3 trophies website. There's many more people looking for the same thing in their Homefront boosting thread.
i play this game regularly to this day, and i too would like help getting the full boat trophy (also the other 2 party related trophies)
my PSN is KRISHANKO (all caps, if it matters)
Like a post said up on this page head over to ps3trophies.org. There are morre then enough people looking for help over there.
