I have a 19ft Alum, fishing boat with a marine radio that I turn to channel 16 and leave on while on the lake. Over 25 yrs at the lake I can remember close to a dozen times we have been able to help someone during a crisis. Another advantage is eavesdropping on conversations of other fisherman as they change channels to talk. Many times I have talked to our houseboat while I scouted camp sites saving alot of time. Marine radio's are a no brainer! Get one on your boat!
