How would it feel to sail a Rocheworld ocean?

A couple days ago, I posted this question about what it would feel like to walk on a Rocheworld.

For some background, a Rocheworld is a double planet system where the two planets are so close together that they have actually started merging together. This is unlikely to occur in real life, but it is still cool to think about. I recommend checking out the original question and answer if you're at all confused.

The answer I got was that it wouldn't be extremely different, but over time you would notice that gravity was different in different areas. If I'm interpreting the answer correctly, gravity would be lower on the opposite ends of the Rocheworld and in the region where the two planets overlap and would be heavier along the middle of each planet.

Now that's how walking would feel. However, in the Issac Arthur video I linked he mentioned that these Rocheworlds could very well be mostly water with continents on the ends of each planet.

This leads to my two main inquiries: How would the gravity of a Rocheworld affect the ocean currents, and could you sail from one half of a Rocheworld to another?
