Pour in orange juice, pineapple juice, and coconut rum into the glass.
Carefully and slowly pour in grenadine juice next to the inside rim of the glass. Grenadine is very dense and heavy so it will naturally sink to the bottom of the glass.
Slowly pour the dark rum over the top and let it float on top.
Serve Bahama Mama layered but it does need to be stirred before drinking. So use a straw or a long spoon to stir the cocktail for a few seconds to mix all ingredients.

Notes
Coconut rum: choose your favorite! Not all coconut rums are created equal, so make sure to use your favorite! They can be sweeter, stronger, or have more coconut flavor. RumHaven brand, for example, is sweet and not strong. It tastes more like coconut liqueur, mild and very sweet. Parrot Bay 90 proof rum has a very strong coconut taste but it is quite strong. So make rum selection according to your personal preference.
Pour in grenadine:carefully and slowly pour in grenadine juice next to the inside rim of the glass, it can be touching the inside wall of the glass. Grenadine is very dense and heavy so it will naturally sink to the bottom of the glass.
Serving: You can serve a Bahama mama layered because it looks beautiful, but it will need to be stirred before drinking. So use a straw or a long spoon to stir the cocktail for a few seconds to mix all ingredients.
