The type is like those used on small boats but I don't recognize them.
They are both from 3539 - Police Patrol BoatThe big one goes on the bow, and the small one on the life boat!The set had many sticker that you could sellect and put on it, including paymobil logo stickers.
Panos nailed it once again The small one can also be found in some other boats like this one http://playmodb.org/setpics/3574.jpg
