The places you don't want them is where they can be walked on and where they are shaded. That being said, I am sure you are saying to yourself that the best place is on a raft behind the boat and you are right to some degree. I have mine mounted on the dodger
and radar arch
. Mounting on the lifelines
is not such a good idea, though tempting. No matter where you mount them, they will be effected somwhat by shading.
, radar arch
, are the most common.
