i dont have a boat but a buddy of mine does. and i got a funny story about it. we were shootin on a lake and we had our lights going, and some cops came over on a boat and said that we needed to have a trolling light or something like that(a little green light) even though we had all our lights on. we asked em y we need it even thuogh we had the lights and they just said because we do. we thought it was pretty funny at the time.
