Stabilized by
Florida’s only Seakeeper-stabilized glass-bottom boat
A glass-bottom tour spends most of its time stopped over the reef, which is exactly when ordinary boats rock the most. The Transparensea carries a Seakeeper gyro stabilizer that pushes back against that roll, so the view through the glass stays steady.
Up to 95% less roll
at anchor, at drift and at low speeds, according to Seakeeper.
Seakeeper’s technology page
See the difference
Most boats roll side to side with every passing wave when they stop. On a glass-bottom boat that means the reef swings in and out of the windows, and that swinging is what upsets stomachs.
The Seakeeper sits inside the hull. A flywheel spinning at up to 9,750 rpm in a vacuum-sealed sphere tilts against each roll and pushes the boat back level, automatically. Nothing hangs off the hull, so it never touches the reef.
Who it helps most
Kids and grandparents
A steadier deck is easier to stand and walk on, so everyone can move between the windows and the rail.
Anyone who gets queasy
Less rocking means far less of the motion that makes people feel sick. We still suggest bringing what usually works for you.
Reef watchers and photographers
The reef stays in the frame, so you can follow a turtle or an eel instead of losing it every few seconds.
Built for looking down
The Transparensea is a 46-foot glass-bottom boat built in 2023 with 16 glass viewing windows. The Seakeeper is part of what makes those windows worth sitting at: a steady boat means a steady view.
Every tour is aboard the same stabilized boat
Starts with the sunset
Night reef tour
Starts with the sunset from the water, then the reef after dark under the boat’s underwater lights. Eels, octopus and lobster come out to hunt.

Late afternoon into sunset; midday bayside trips on windy days
Bayside and sunset cruise
Calm water on the Florida Bay side: dolphins, mangroves, manatees and a Keys sunset. It is also our plan B when the reef is too rough.

Seakeeper and seasickness questions
Will I get seasick?
Much less likely than on most boats. The Transparensea is the only Seakeeper-stabilized glass-bottom boat in Florida. Seakeeper says its gyro eliminates up to 95% of boat roll at anchor, at drift and at low speeds, which is exactly when we are stopped over the reef. No boat can promise that nobody feels any motion, so if you are prone to seasickness, bring whatever usually works for you. How the Seakeeper works.
What is a Seakeeper?
A gyro stabilizer mounted inside the boat. A flywheel spinning at up to 9,750 rpm in a vacuum-sealed sphere pushes back against the rocking motion waves cause, automatically and without anything hanging off the hull. Seakeeper rates it at up to 95% less roll at anchor, at drift and at low speeds.
Why does a stable boat matter on a glass-bottom tour?
Because you spend the tour looking down through the glass. On a boat that rolls, the view swings back and forth, which is hard on stomachs and makes the reef hard to follow. With the roll cut down, the reef stays in the frame, kids and grandparents can move around more easily, and photos come out sharper.
