A Boat cocktail is everything you want in a refreshing drink—cool, citrusy, and just the right amount of sweet. It’s the kind of cocktail that instantly transports you to a breezy afternoon by the water, whether you’re actually on a boat or just dreaming of one. I’ve made this drink countless times, and it never fails to hit the spot, especially on a warm day. Let’s get into how to make this simple yet satisfying cocktail at home.

Boat
Ingredients
You’ll need:
- 2 oz (60ml) white rum
- 1 oz (30ml) fresh lime juice
- 0.5 oz (15ml) simple syrup
- A splash of soda water
- Fresh mint leaves (for garnish)
Glass: A highball glass works best, keeping the drink crisp and cold. If you want a more laid-back vibe, a mason jar does the trick too.
How to Make a Boat Cocktail
- Fill a cocktail shaker with ice, then add the rum, lime juice, and simple syrup.
- Shake well for about 15 seconds until the mixture is well chilled.
- Strain into a highball glass filled with fresh ice.
- Top with a splash of soda water and gently stir.
- Garnish with fresh mint leaves and serve immediately.
Tip: Fresh lime juice makes a huge difference here—bottled juice just won’t have the same bright, zesty flavor.
Make-Ahead & Storage Tips
Want to prep ahead? Mix the rum, lime juice, and simple syrup in advance and store it in the fridge for up to 24 hours. When you’re ready to serve, just shake with ice, pour over fresh ice, and add soda water.
Since this drink is best enjoyed fresh, it’s not ideal for long-term storage. But if you need a batch for a party, scale up the ingredients and mix in a large pitcher, adding soda water just before serving to keep the fizz.
How to Customize Your Boat Cocktail
Want to tweak the flavors? Here are a few easy swaps:
- Swap white rum for dark rum for a deeper, richer flavor.
- Use lemon juice instead of lime for a slightly different citrus kick.
- Try agave syrup or honey instead of simple syrup for a natural sweetness.
Fun Variations
Tropical Boat
- What to add: A splash of pineapple juice
- How to make it: Follow the original recipe, but mix in pineapple juice before shaking. Garnish with a pineapple wedge for extra island vibes.
Spicy Boat
- What to add: A thin slice of jalapeño
- How to make it: Muddle the jalapeño with lime juice before adding the rest of the ingredients. It gives the drink a subtle heat that pairs beautifully with the lime.
Berry Boat
- What to add: Mixed berry syrup instead of simple syrup
- How to make it: Shake as usual, then garnish with fresh strawberries, blueberries, or raspberries for a fruity twist.
Non-Alcoholic Version: Want a Virgin Boat? Just skip the rum and replace it with extra soda water and a dash of almond extract for depth.
What to Serve with a Boat Cocktail
The Boat cocktail pairs beautifully with light, fresh foods. Here are a few perfect matches:
- Grilled Fish: The smoky, charred flavors of grilled seafood go perfectly with the bright citrus notes of the drink.
- Fresh Salads: A crisp garden salad with a light vinaigrette is a great pairing for this refreshing cocktail.
- Fruit Platters: Sweet, juicy fruits like mango, pineapple, and berries complement the zesty lime and mint flavors.
Pro Tips for the Perfect Boat Cocktail
- Use quality ice. Large, clear ice cubes melt slower, keeping your drink cold without watering it down too quickly.
- Shake, don’t stir. Shaking helps blend the ingredients and aerate the drink, giving it a smoother texture.
- Adjust the sweetness. Like it more tart? Use less simple syrup. Prefer it sweeter? Add a little extra.
I love how easy this cocktail is to make, but it always feels special. The crisp lime, the cool mint—it’s the kind of drink that makes you slow down and enjoy the moment.
