I was told to be very cautious about CHILDREN life jackets. The ones that specify the weight of a child. They must / should have a crotch strap to prevent the child from sliding out of the jacket in the water. I am in US CG waters.
Ive researched this over and over. I all depends on what the label states. Some will say must be worn on Type 2 commercial vessels. Based on the text: must this be worn in a fishing boat to be legal?
