The Diversity

The Diveboat Diversity

SunStar Aquatic Services was started by Karen Orsak and Capt. Tony Coulter in the winter of 1989. We wanted to start a dive operation in Southeast Florida with no hassles, no overcrowding, and a lot of fun. We were tired of dive operators who did not care except for how many people they could cram into a small boat!

Since then our operation has bloomed into a fun experience for all types of divers from the novice to the most experienced. Our divers have been coming back to us since we started! Our staff is very experienced and dedicated to giving our divers a SAFE and ENJOYABLE dive trip!! So come on down relieve some stress, bring the family, and come out and play!!!


We invite you to explore the diverse, beautiful, underwater paradise of Southeast Florida in a very unique. and personal way. Our 30` foot Island Hopper dive boat “DIVERSITY” caters to groups up to 15. USCG licensed Captain, NAUI and PADI instructor, and Rescue Certified and above crew onboard. Over 40 years diving Boca Raton/Delray/Deerfield Beach Florida. Safety is number one with our charter.

We have over 30 different reefs to dive ranging from 20` to 130`. With some different “tech reefs” past 130`. We also have over 15 different wrecks ranging from 20` to 130`.and deeper. Our longest boat ride to these great dives is no longer than 40 minutes from our docks, and the average trip out to dive is 15 – 30 minutes!

The longer I live, the more I realize the impact of attitude on life. Attitude to me is more important than facts. It is more important than the past than education, than money than circumstances, than failures, than successes, than what other people think or say or do. It is more important than appearance, giftedness, or skill. It will make or break a company…a church…a home. The remarkable thing is we have a choice every day regarding the attitude we will embrace for that day. We cannot change or past… we cannot change the fact that people will act in a certain way. We cannot change the inevitable. The only thing we can do is play on the one string we have, that is attitude… I am convinced that life is 10% what happens to me and 90% of how I react to it.
