I bring only rum, beer and soft drinks to the boat. Sue brings wine & water. I drink the wine with her but I won't drink water from plastic bottles. In fact I won't drink ANYTHING from plastic bottles. I think it is a health hazard & the bottles are disastrous for the environment.
(Editorial comment aside!)
I've been favoring Shipwreck (Brinley Gold) rums for the boat, namely vanilla, toasted coconut & spiced. I like the tall, thin bottles and the labels. The taste is good, too. I drink them on the rocks. I might have on board (if I bring for special occasion) Goslings for dark rum & Malibu Black for coconut rum with more kick.
For beer, I always have Leinenkugal Summer Shandy on board for me ... I like lemon citrus in beer. I may have Corona if I remember to bring limes. I found that Sam Adams Porch Rocker is delish as it is not really a shandy and it is verrry smooooth. I buy it when I stumble into it. I don't see it everywhere. People tend to bring the beer they like, so I don't worry about having a selection on board. I just stock what I like and what Sue might have.
Soft drinks have to include Regatta ginger beer. I like the labels & the bright green bottles. I drink them alone and mixed with rum. Anything out of a glass bottle tastes better and is cooler, so that is the reason I don't buy Gosling's ginger beer ... I only find it in cans. I'll drink only Pepsi & Coke from cans. I used to drink beer from cans when I was in college. I wasn't fussy, then, I'm much older now.
For wine, you can't go wrong with Pinot Grigio. That seems to be everybody's favorite on a sunny day. That's all I need to buy to keep Sue happy. She'll drink a Blue Moon beer or something equally innocuous. But she calls me a girl for drinking flavored rum and fruity beers, just to let me know that she doesn't put up with any crap when I make fun of her selections.
