Under the seat
In my state, we dont have to have a flag, on a whistle. We also do not have to have a flair unless in "Coastal water" which I was told I did not need in the intercoastal, only if I left the jetties.It did. Just wasn't sure where it went. Also idk the laws by you guys but does a distress "flag" that came with my coast guard kit count as a flare?
