In a cocktail shaker filled with ice, pour in the white rum, dark rum, coconut rum, fresh orange juice, pineapple juice, grenadine, and fresh lime juice.
Shake well until the mixture is thoroughly combined and chilled.
Strain the mixture into a hurricane glass filled with ice.
Optional: Garnish with the lime wheel and a cocktail umbrella.
Notes
Optionally, you can also layer the grenadine at the bottom of the glass before adding the rest of the ingredients to create a visually appealing gradient effect.
