Any one have any experience with these?

We'll be chartering a power cat, BVI in Feb, with plenty of adults and two five year old kids / marginal swimmers. Looking at these bracelets as an extra-layer of protection.

Thx

I am not sure how effective they would be if falling off a powercat while underway. I would bring with you good quality proper fitting life vests for each child. Keep them in the cockpit areas underway. There is also still plenty of time to have a 5 year old swimming like a fish before the trip.

The two main places to congregate on a power cat while underway are the flybridge and the bow area. The main concern for kids in the flybridge is falling down the stairs or falling over and hitting something hard due to the movement of the boat. Obviously, the main concern while underway in the bow area is falling off the front, especially if they’re sitting on the bow seats on the front corners of the boat. Consistent oversight by the adults and good life vests (always on unless in a very secure situation) would be our strategy.

Unfortunately, we witnessed a boat roll over a few years ago by the airport after hitting the reef. There were younger kids on the boat, and everyone was OK, but they said the boat went down within a minute. You never know - so the vests would not be an option for us (just bring comfortable neoprene ones with bright colors).

You might consider bringing a couple of kids inflatable life vest.
Would not take up much room in luggage and more comfortable to wear.
Lots of options out there.
