Pour the strawberry liqueur into the bottom of a chilled highball or hurricane glass.
Fill a shaker with ice and add the gold rum, white rum, coconut rum, pineapple juice and lemon juice. Shake well until thoroughly chilled.
Fill the serving glass with fresh ice and slowly strain the shaken mixture over the back of a bar spoon, allowing it to float gently over the strawberry liqueur. The layers will gradually blend into a beautiful tropical sunset.
No garnish is required, although a pineapple wedge or strawberry complements the presentation beautifully.
