The Captain's Cooler
Garnish with blueberries and raspberries on a cocktail stick.
Stir the rum, liqueur and sherry together with ice until very cold. Strain into a Sling glass filled with ice. Top up with pineapple juice. Serve with a straw.

Fino sherry can be substituted for Manzanilla; they're virtually the same thing.
