Boat survived Ivan and only was stuck in mud for 4-s,days until a high tide; however, some not so friendly visitors, broke in and stole items that were not removed.They left the orange life jackets, but took the two automatic vests (type IV), my yet to be installed Lectrasan, winch handle, 9' gaff pole, and misc. navigation plotting tools. Of course they wouldn't take my old -cheap binoculars! Anyhow; Does anybody have a review of the Ecohorn, sold by West Marine, as I am considering that for replacement of my portable safety horn.
