So many tourists traveling here take the boat for island hopping or for other water activities, but also so many do not wear life jackets on the boat when they really should be!
Forget about how you would look in photos with the jacket on, it doesn't matter how good of a swimmer you must be, please put it on the moment you step onto the boat - and put it on properly! The straps should be tight enough so it won't flip over if you fall in water.
The weather is very unpredictable here, it can be sunny at any given point of a day, but with a strong storm around the corner like the one we just had.
