Split, Croatia Tours/Recommendations

[22CeeBeeNC22]

Will be in Split for the day in late May. I am reading that much can be done on foot independently. I would like to incorporate some type of water tour into our day as the waters there look amazing. Any recommendations specifically or tour operators you've had positive experiences with that you can share?  We will be in port 8AM-7PM. Thanks in advance.
