I too am sorry as I've known the loss of three individuals, in seperate situtations who perished in small boats, in the straits. Pdf's won't necessarily do you any good if you don't get removed from the water in a reasonable amount of time. My suggestion: Buy a sea-worthy vessel if you're to go to sea (then have your Pdf's readily available).

I'm very sorry for your loss, but hopefully and at least the people who read this board will learn something as a result
