Wreck and Reefs: 3 tanks!

Wrecks and Reef...None better 


UPDATE: The Marissa dive boat is now docked at Mission Bay Sportcenter.

This will be a 3-tank, no-profit, local trip aboard a well-appointed charter boat. If you don't have a buddy you may team up with another single on the boat. The boat provides tanks (Al 80s) and weights (bring your own if you like). Nitrox onboard for an extra charge. You provide all other gear. The boat also provides food and drinks between dives.

COST: $72.77 (Paypable via Paypal after you RSVP on the right.)




  • HMS Yukon: 365' intact Candian destroyer repurposed as an artificial reef. Lays over on it's side in flat sand. 70-105' deep.

  • Green Tank: Unique site in Pt Loma kelp beds.  Natural erosion has created "tables" into the reef and below them are crevices for your exploration. 60-75' deep.
  • Seven FathomsA Pt Loma Favorite. 50-80' deep


To make reservations: Simply RSVP here (first) then pay via the Paypal interface that pops up. (Safe and secure... I've used it for years.)

BOARDING: When you board the boat, EXPEDITIOUSLY sign in (boat manifest and boat liability forms), assemble your gear (keep dive boxes/bags OUT OF the walkways), and then make room for others. Large boxes and bags may be stored on the second level. Small drybags can be stored in the v-berth. Keep bags OFF the bench seats. (Those are for people.)

SKILLS: Kelp and current possible. Because of the depths involved this trip is considered "advanced"... though a strong skill-set at any level will allow you to perform these dives safely. Stay within your skill-set and comfort level.

If you back out less than 96 hours before departure (or "no call, no show") you are on the hook for the money. No refund. (To back out fully you must cancel your RSVP here and request a Paypal refund.) If you back out less than one week before the boat leaves you will be refunded half your boat fee*. The other half may then be used to entice another diver to take your spot. 8+ days= full refund*. (*All refunds subject to a .31 Paypal fee and 9% admin fee.)

Dive Boat Tipping Guidelines: Tipping Info & Advice here


  • Hydrate really well.
  • Take Bonine if you think you're at all inclined toward seasickness.
  • Eat a decent, non-greasy breakfast.
  • Bring something to keep you warm between dives (overcoat, boat jacket, etc).
  • Bring a torch for peering into nooks and crannies.
  • End your dive close to the boat (unless you enjoy long surface swims).
  • ALWAYS bring your dive essentials: A safety sausage, knife, and whistle (at a minimum)!
  • Don't forget to tip the boat crew if they do a good job for you. This one's just as important as any other point in this list. The DM is there for your safety. Take care of him/her!

Boat Etiquette Reminder:

  • Don't be late.
  • Space is limited on a boat. Stow all your gear where directed to by crew.
  • Keep gear out of the walk-way, damnit.
  • Put your fins on at drop-in point (not forward and then flip flop over people's feet and gear).
  • Don't rinse your mask or other gear in the CAMERA BUCKET!
  • Don't clog up the marine head with Baby Ruth bars, tampons, or similar.
  • If you have to throw up, do it downwind (leeward), NOT IN THE HEAD.
  • If you have to cancel, do it well before the cutoff time so Bill has a chance to sell your seat.


The Virtual Donation Jar is always out (for the Meetup site costs and general fund). It's strictly voluntary, but is very much appreciated and needed: Click here for the DONATION JAR

If you have not submitted a Liability Release for Power Scuba, please follow this link to the file, print, sign, and bring to the event along with your C-Card (scuba certification card). You need to do this at least once a year:  Liability Release and Assumption of Risk

You must also read this: Disclaimer and Clarification... AKA Terms of Service...AKA Terms and Conditions

Anyone with a medical condition possibly counter-indicitive to diving must have a doctors signature on a diving waiver form and submit signed form to Bill Powers (or an organizer) before they may attend any Power Scuba event. YOU MAY NOT ATTEND AN EVENT WITH AN UNDISCLOSED MEDICAL CONDITION. Doing so is grounds for expulsion from the group. Here is our medical statement: Medical Statement Therein you'll find a Doctor Waiver form as well.

Attending any scuba event Power Scuba facilitates constitutes attendee's affirmation they are medically fit to dive, certified to dive by a nationally-recognized agency, have the necessary skill & training level for the dive being offered, have read the Terms and Conditions, and have submitted a signed Liability Release to an organizer.

Important Note: It is not the organizer's role to lead your dive (or to wait for you after you come out of the water). He/she merely facilitates you getting to the pre-dive meeting location. The Organizer will not assign you a buddy nor will he/she be leading the dive as a "group dive". Visibility and liability do not allow for that. Nor will the Organizer tell you whether you are skilled enough to make any particular dive. That is for you (only) to decide. When you enter the water, you (and your buddy) are on your own. You must plan and execute your dive with your dive buddy only. Once members arrive at the meeting spot, the Organizer becomes simply another diver.

For Boat Dives: Any overage (usually less than $50) resulting from our local dive boat trips is put into a dedicated Group Boat Fund. This allows us to make up the difference if we don't completely fill up a future boat charter. No other use is made of this money.

Power Scuba bears no responsibility or liability for a member's loss (gas, airfare, hotel fees, etc) in the event of a cancelled event.

Your participation constitutes your affirmation you agree to these above rules and disclaimers.... and that your buddy(s) (if applicable) has read and agrees to the same.

1010 Santa Clara Place, San Diego. Still in the Mission Bay area, but not near the old place.

    I was lucky enough to visit the Yukon for the first time on this trip, and of course now want to see the rest of it! The call was the right one since we all got to carry on with our terrestrial lives at the end of the trip.

    The refund issue is moot, I've worked and played at enough ski resorts to know about refund policies due to weather, we choose to participate in a sport that is dictated by mother nature and physics, no chalk lines here. I have been on other dive boats (bigger with more room) where they make the "chuckers" suck it up while the others kept diving. Actually got puked on as I surfaced on the leeward side...bad timing or revenge...???

    Hey Gang; With the following factors applied, its the boats policy for no partial refunds. First, there was no predicted weather that would interfere with the days events. Swell reports, etc were well within boat operations and once the first dive was completed, its an "all in event". IF the dive had been called prior to leaving the dock due to forecasted weather conditions it would've been a different story. However, since there was no such evidence that the weather would turn like it did, our first dive was complete, and the condition of some divers on board, the call was made based on safety of all. I know this isn't what you all want to hear, yet I agreed with the call that was made and the reasons made for it. So we will have to stick with the policy of the boat. I have been on this and other boats before when these calls were made and yes the money came to mind yet if I was the one in "distress" for whatever reason, I would hope someone would make the same call.

    • Bill P.

      Just to add a bit: A mere one or three sick passengers is never a valid reason for turning the boat back, but couple a significant percentage of the attendees feeling bad with the worsening conditions and there wasn't much more that could be done. Indeed, once a dive has been performed the charter monies spent are considered "all in". This is normal boat policy and if you've ever experienced otherwise please chalk it up to a very soft heart (or weak moment) on the captain's part! :-) We never like for this to happen, but it simply comes with the sport we all love.

    You (and Captain Lora) made the right call. There were some pretty green faces on the boat...I could have very well become a "sympathy puker" too. As far as a partial refund...It's like going on a fishing trip where no fish were caught...sometimes you just get a nice boat ride and some snacks.

    My two cents.

    The one tank dive was enjoyable for me. It would be nice if Power Scuba could request a partial credit or discount on a future trip with the Marissa given the situation. The other recommendation I would make is please arrange to have the public bathrooms open at 6am or 6:30am at the latest for 7am Marissa departure times. All the nearby public bathrooms were locked/closed. Thanks

    Well....the weather definitely turn and unexpected path. Its unfortunate yet sometime that is the way of things. After the first dive we had 4 divers down (sick) and others probably trying to maintain composure...that would be me. If I seen one more person puck...I would've been right there with ya! Still had a great bunch of people and made a lot of new dive acquaintances. Sorry that we had to make a call with the rapidly worsening conditions. We always have to look at the overall picture and make the safe call. There will be other great dives for sure....and probably some crappy one too!

    Hey gang...we can save some time if everyone brings a signed liability form. I require this on every boat dive, regardless if you have already signed one for PS, you will have to sign another to dive on the boat tomorrow!!! See you all tomorrow.
