Where are beaches with kayak rentals in Bahamas, St. Maarten or St. Thomas?

[Meesh]

We are trying to find out where to go to enjoy some sun and kayaking during our shore excursions.  We don't want a snorkeling or hiking combination, just a nice beach where our child can safely go kayaking.  

 

We stop in Nassau, Bahamas, Charlotte Amalie, St. Thomas and Philipsburg, St. Maarten.

I am certain you can find kayaking at any of these ports, especially if you consider third party excursions. Many hotels on the beach offer something along those lines, so if no one provides any specific recommendations, I would recommend googling for things like "st martin kayak rental"
