ABOUT CAYMAN MARINE LAB

Established in 1986, and always run by the same person, Cayman Marine Lab will be the most experienced operation you could dive with in Grand Cayman. Most dive businesses employ divemasters who typically stay in the game for only a year or two and therefore never entirely acquire the experience to learn their craft. One of the ways we use our expertise is in bringing you to fresh dive sites that have never been visited by any other operation.


Cayman Marine Lab caters to families and individuals interested in a smaller and more intimate eco-diving experience; however, it is not just diving and diving lessons. We offer many types of private charters, including tropical marine biology, stingray and snorkeling trips as well as deep drop fishing charters. CML offers a variety of visitors many things to do while in Grand Cayman.

For as long as I can remember, I have always been crazy about being on the ocean. When other kids were playing with trucks and army men, I was playing with outboard motor parts and fishing gear. I shocked my school guidance counselor by breaking a string of "I want to be a policeman, fireman or shortstop"...with the charter boat captain. He, of course, tried to dissuade me, however, while still a teenager; I acquired my Coast Gaurd Captains License.  I worked as a commercial fisherman through my youth.  My first diving certificate was in 1974 with the YMCA. My brother and I survived a wild diving youth in the northeast Atlantic. A typical outing involved running out and then returning after dark through one of the most treacherous inlets in Massachusetts. We covered the entire 20-mile coast of New Hampshire and then continuing another 10 miles offshore to an island off Maine in a leaky 16ft rowboat with a temperamental 35hp motor slapped on it. Somehow we always made it back. And the parental concern was usually overwhelming (they had a lot of kids), with statements like "did you get any lobsters"? I learned from many mistakes.

Commercial fishing proved to be too fickle, so I decided to become a marine biologist.  I was very fortunate to have Professor Gene Kaplan (of Peterson field guide to Coral reefs and Southern Seashores fame) as my mentor.  Eventually, with a Commonwealth and prestigious ITT Fellowship(a more revered form of the Fullbright), I would complete two graduate degrees during my six years in Australia. I traveled nearly every mile of the Australian coastline in the most uncomfortable truck ever manufactured, to collect specimens.  After six months of eating what I killed and sleeping on top of the said truck; I returned to the lab to push out nearly twenty scientific papers published in highly respected journals throughout the world. 

I took a position at Hofstra University, running a marine lab in Jamaica. We hosted as many as five academic groups simultaneously - chaos! To be sure, it was a long but rewarding year, requiring the wearing of many hats. Everyone had an enjoyable experience in spite of having guns pulled on us during some field trips. 

Many of the visiting professors said they would follow me if I went on my own. I decided to take the chance and open in beautiful and safe Grand Cayman.  The Cayman Marine Lab took off with academic groups raving about the marine environments Cayman had to offer.  Before long tourist divers looking for small groups and knowledge of what they saw on dives, filled our boats.

Fast forward 33 years and countless thousands of dive charters, (more than any other captain in Cayman's history), making CML the most experienced operators on the water today.  We specialized in getting our customers to the least dived and pristine reefs in Grand Cayman and offering the marine education to enhance any charter.

Danny was born Caymanian and made his first dive on the north wall when he was just 11 years old. He started working for CML on a part-time basis when he was 15. After graduating high school he became a PADI divemaster and acquired his captain's ticket. He worked fulltime for 2 years before starting at University.

Danny remained close to the business and worked during all of his breaks which, remarkably these days, allowed him to pay for his 5 years of studies. Since graduating from the from Georgia Southern University he is back fulltime.

Although just 25, he already has 10 years experience and thousands of dives under his belt. His keen knowledge of tropical marine fauna and ecosystem make him a tremendous asset to CML as a naturalist.
