Yacht Serena III sinks off Ft. Lauderdale

All of the late 80's Trojan Internationals I've been involved with had a separate float switch that sounded a small electric horn on the exterior of the boat with high water. Some even had it tied to the main horn if not equipped with air horns.

I always thought that was a clever idea.

Nothing other than that it is hard for me to accept the fact that no one noticed the boat was full of water until it was about to roll over.

No offense, but Serena III looks like a converted trawler or ice-breaker.

What has what it looks like got to do with why it sank?

Well, to me it looks like someone converted it to be a yacht, and maybe whatever modification took place was a contributing factor. It looks like it was a ferry at one time, by her configuration.

It probably looks that way because it was built by a builder who normally only builds commercial boats. It was a "special" order, one of a kind. Regardless it did get Class from ABS at completion. That Class expired in December and they didn't renew.
