I know the jetties well and it can be a real washing machine out at the end of them...what a ride! For your next boat, check out a R.A.M. (remote mic) It stays at the helm and is wired to your VHF...or a handheld at the helm.
A VHF down below is useless when the defecation is hitting the oscillating, rotating, air-moving mechanism.
Thank you for sharing...I take all of these type of stories to heart...for when I have my next "holy crap" moment.
It gives me chills thinking about jumping onto a jetty rock!!!
