Yes, I've heard about some instances along the coast of Mozambique, but it is mainly higher up toward Somali on the East Coast and on the West Coast in the area of Nigeria...

However, as far as I know, they prefer to target large vessels with valuable cargo such as oil, etc...

I don't think anybody will take you out on a cruise which will be too dangerous and/or risky.

No harm in asking these questions, @chocolatescorpi! Safety first! That's the wise thing to do...lol!
