Not a normal diving liveaboard
Too crowded, actually this is not a normal diving liveaboard, they have 1/2/3/4 days trip for your selection. If your whole trip is for diving Sima 3 may not suitable for you. However, if diving is part of your itinerary and you want to spend only 1 or 2 days for diving then Sima may good for you.
