Most Cozumel boat trips head for the big reefs, but this one adds a sunken ship and a boat with a window onto the sea floor. A glass-bottom boat has a viewing panel in the hull, so passengers who prefer to stay dry can still see fish, coral and wreckage while the guide points out what is below. Snorkelers can slip over the side at the stops, which include shipwrecks and reef sections, and then return to snacks and beer on deck. The trip lasts about four hours, which is a comfortable half day, and it is rated 4.6 from ninety reviews, a solid result for a mid-priced tour. It works for mixed groups in particular, because the youngest and oldest members, or anyone nervous about open water, can enjoy the same sights without entering the sea. The glass also shows plenty when the surface is a little choppy, though rough seas can cancel any boat trip. Think of it as a relaxed, social way to see the reef rather than an athletic snorkel marathon.
Why go
The shipwreck stop is the draw, a rare bit of human history on a reef-focused island, and the glass makes the trip inclusive. For couples where one partner loves snorkeling and the other does not, it solves the problem neatly.
How to do it well
Sit near the viewing panel at the start, put on sunscreen before boarding, and bring a hat, a towel and a light layer for the breeze. If you plan to snorkel, check the fit of your mask early and use a vest if you are not confident.
Take motion sickness medication beforehand if you are prone to it, since a boat with a glass floor still moves with the swell. Keep your hands off the coral and the wreck, and follow the guide on where to enter and exit the water.
What to know
The beer and snacks are part of the trip, but alcohol and swimming do not mix, so pace yourself before you get in the water. Conditions determine what the boat can reach, so the exact stops can vary, and the trip may be rescheduled or cancelled in rough weather. Boat capacity can be large on busy days, so book early in the cruise season. Visibility is the key variable, and the clearest water is usually in the calm months.
