Welcome to MDA Boat Diving!

We dive "LOCAL STYLE": Longer dives based upon your abilities, a wider choice of dive sites, spacious boats totally designed for divers, a very wide variety of sites, and great prices all add up to what we do best... dive!  We make every effort to give you as much "Guam bottom time" as possible. If you are not local, we highly recommend you to dive with one of our MDA Trained Dive Guides.  If you are an experienced diver and traveling with another diver equally experienced please consider joining our 5-Star Divers club to keep your diving costs low.

Email instruction@mdaguam.com to book your dive guide and get more information.

Q: What is our experience? No other dive company on Guam has the experience that we have! We've been diving on Guam since 1974, and have specific information on virtually every dive site on Guam.  Our staff is totally committed to your diving enjoyment and safety.  We also have special afternoon trips on the weekends, that feature a wide diversity of dive site’s that are not frequently visited during the morning 2-tank dives. There are also many evening trips for night dives, see our dive schedule for an updated list of our monthly dives.

Our boats?  We have two 42' Newton custom dive boats (Sun Chaser and Sea Fantasy). Our boats are equipped with full electronics, individual tank holders, pressure showers, and a host of other "diver friendly" facilities onboard.   All of our boats were designed for divers from the keel up, and they are the finest dive boats on Guam!  An added bonus is that our boats are usually based at two different marinas 8 miles apart. This gives us a greatly expanded range and dive site selection. Maps to each of the marinas are available in the dive shops.

Q: Do you have a group of 10 or more?  Why not consider chartering our boats.  We can easily accommodate groups up to 42, and the boats are available for diving, snorkeling, trips at sunset, dolphin watching (about 90% chance of seeing them), parties, weddings, and whatever you'd like to do! Email retail@mdaguam.com for more information and to check availability.



Q: Do we have daily boat dives? Yes, we go out every day at 9am.  This trip is open to everyone and all certifications.  However if you are not local, we recommend you to dive with one of our MDA Dive Guides.  Be sure to ask about our free tank delivery!

What does it cost? Take a look at our options here.

Q: What other trips do you offer?  Our weekend boats are always a hit. We post our monthly boat schedule two weeks prior to that specific month. If you are planning a head to come to Guam, it is best to wait a few weeks prior to your visit to book your diving. To view this month’s schedule :  Go here to see them.

Q: Do you always leave from the same marina?  No, and you'll notice that we sometimes leave from 3 different ones.  We depart from the marina that’s closest to the dive sites that we have listed.  Why? less travel time, more dive time and depending on the season.
