This is great for use on a boat because it's so easy!

Two cans/bottles of beer
One can of frozen limeaid
1/2 can (use the limeaid can) tequila

Stir up and drink; makes two large ones

Not quite as good as other more pricy and complicated recipes, but it
doesn't require a blender and I defy you to be able to tell the
difference after the second one.
