Glass bottom boat

[margincall]

This may be a weird question, but here goes.

Both cruises that we are considering stop at Half moon cay.

We are seniors,that are way past our active years,but are also not huge on lying out at the beach.

We noticed an eco glass bottom boat tour,which leads me to my questions. Over the years,I have,at times been susceptible to vertigo(which thankfully rarely effects me on board cruise ships.)

But many years ago in the Florida keys,I was on a glass bottom boat tour,that got me sick,as the boat was still and bobbing,while we looked through the bottom.

So does anyone know if this boat,just sits still like that,or is it like the semi subs which keep moving and never give me issues.

Sorry for being so long winded
