Welcome aboard the Marissa. Let’s talk about your Scuba Dive in San Diego! Below you will find information on WHAT TO EXPECT on your trip, our cancellation policies, as well as some tips that will make your boat ride more enjoyable.  No need to thank us, (just yet anyway) we are happy to help! If you find you are in need of further help … feel free to contact us at any time. 


What we PROVIDE:


➢    AL 80 tanks with DIN/YOKE Valves 

➢    Air Fills

➢    Hard Weights 

➢    Food and Beverage

➢    Hot Tea, Coffee, or Coco

If you are on a special diet, we can do our best to make sure we have food for your specialness;) Please contact us to let us know!

You will reap the benefits from our years of experience, IF you bring the following along with your dive gear, of course. Do not underestimate the importance of being able to get warm and dry. (NO, your HOT buddy’s (or boat crew’s) body-heat is not what we are talking about!). The water temperature is between 50-52 degrees; with multiple dives, getting warm between them, will make your day that much more AWESOME! 


➢    Exposure Suit: 7mm wetsuit or drysuit

➢    Dive gear (unless you are renting)   

➢    Sunscreen

➢    Dry Towels

➢    Dry Clothes

➢    Sweatshirt or jacket to keep warm

➢    Seasickness Medication

➢    Government Issued ID 

➢    Certification Card

➢    Tip for the Crew 


Trust me, if you have ANY thoughts of seasickness, you may want to try some seasickness medication (JUST DO IT!), such as Dramamine, Bonine or even Ginger.  Seasickness can ruin your dive trip (and everybody else’s) so please do your body a favor and come prepared. Dramamine comes in a "less drowsy" formula and Bonine is a less drowsy formula, (in my humble opinion) regular strength Dramamine sometimes makes a lot people too sleepy to think right the day of, better to take this one the night before.  We (as in the UNIVERSE) have found the most effective way to ward off seasickness is by taking the recommended dose the night before, then again 2 hours before the trip. But of course….it’s your call.;)

 Your crew works tirelessly to provide you with the best service money can buy … So bring a big tip! HA! Okay, seriously, tips for the crew are not included in the price of any ticket, nope not yours either… We can’t emphasize this enough: Our Crew really does work very hard to provide you the best service around. They are all highly trained, skilled and under-paid professionals. So please show your appreciation in the Tip Jar at the end of the dive. (psst…this means you should bring some cash) It is customary to tip 15-20% of the full price of a ticket; of course you are welcome to tip as much as you want :).


Fun Police:

You may have noticed a little sarcasm, satire, or joking around in this Section. That is for good reason! You are diving to have FUN and your experience should be FUN and EXCITING. Not to mention that you will be in great hands with our crew. 


We have provided these tips so you can have fun while you are on the trip. If you are freezing or seasick between dives or you forgot your sunscreen and are now lobster red; you are NOT having FUN. Since you didn’t start diving to torture yourself, follow these simple tips to having a great time on board our boat!  


All of the dive times listed on our website and your confirmation email are BOARDING times. Meaning the time you need to be at the boat. We depart after everyone has signed in and safety briefings have been given.   

Boarding vs Departure Times

Dive Masters/Guides NOT Provided:


Our Dive Master DOES NOT enter the water with you. It is industry standard and USCG orders in San Diego that our Dive Master/Crew must remain on board the vessel, except in the event of an emergency/urgency on the surface.


If you would like a Dive Master, please let us know, we will be happy to get you in touch with some trusted Dive Masters:)

Instructor Benefits 

Instructor Rides Free:


If you are an instructor, you can ride free with 4 or more full fare students. If you are an instructor with 3 or less students, your fare is ½ of a full fare ticket price. Please feel free to make your reservation right away, and contact me about your instructor status. Our system will only take a $20 deposit per diver and the deposit for the instructor will be applied to the balance.
