I saw a picture posted here within the last week of a cruiser with a Lagunitas IPA in each hand. It’s all I have seen on menus posted on CC. I had never tried one so I bought a six pack and read Beer Advocate reviews. It’s a solid 3.8-4.0 out of 5. AFAIK, there are no other IPA choices, assuming you’re sailing here in North America. At least you’re not hoping for a decent porter or stout. Then you’d be SOL.
