We pitched up in a cove, with three other boats. A delightful way to spend an afternoon.
If you are visiting Sinai do make a point of doing a Lazy Boat trip.
On our boat were a couple of people totting up their diving hours, another couple who had paid a bit extra for twenty minutes one-to-one instruction as an introductory to diving, but were mainly there for the laziness, along with us who were snorkelling (him) and paddling and splashing around (me).
