I went out to Old Garden Beach on Saturday monring with a couple friends. What a great way to spend my b-day!

This Saturday the seas were supposed to be 4-8 feet and mostly cloudy around Gloucester...we woke up at 6 am, checked the weather report and it was not good for diving. Oh well...we'll drive up to Cape Ann, check it out, and turn around if need-be. I had considered going to Nubble, but the report wasn't much better there. At least Cape Ann has a variety of sites, so if we have to call a site, we can go somewhere else.

We get to Old Garden and there isn't a cloud in the sky. I look at the water...it's choppy, but not bad at all! We decided to give it a try, unloaded the car and geared up. I was in a dry suit, they had two piece 7 mm wet suits on. Chris, my roommate and friend from college, broke the bottom of his zipper on the two piece 7 mm and it wouldn't stay closed. At this point we were thinking we'd have to call the dive, but Ed (a college friend visiting from Pittsburg), had a 1.5mm shorty on underneath his suit. He took that off and Chris put it over his entire suit and all was good! Next, after putting our regs on our tanks, my friends let me know that they only have like 2300-2400psi fills. After cursing the dive shop's name for a bit, I examined the tanks and realized they were LP 72 cft steels, not HP. All is good.

There were three of us...two friends from college were with me and neither had dived in this area, so it was quite exciting for them. We got in the water and swam out on the surface for quite a while. There was a fair amount of current and some big waves, but it wasn't so bad if you can tolerate clearing your snorkel every so often.

On the surface Chris signals to me because he is seeing the millions of comb jellies we are swimming through and is a bit concerned. I told him not to worry...they don't sting...all is good.

We decended, swam out for a while on the rocks near the east side of the beach. Crabs, lobsters, starfish, more of the same...vis was good...around 20 feet. Ed was dragging the flag and having a bit of trouble since it had been a long time since he had been diving. I was navigating for the first time ever (we got back!) and Chris was fooling around trying to grab every lobster and crab he saw. About halfway into the dive, I check everyones gauges for air when Chris grabs my slate and writes, "Gauge not working...bad?" At first I thought he meant his air gauge, but we sorted it out and I realized that it was just his depth gauge that was broken. No biggy...two people with depth gauges when the surface is only 30 ft away...we continued.

First dive, 36 minutes, 40 fsw. 1:27 min surface interval

On the second dive, we swam out more toward the center, and turned around early so we wouldn't have as much of a surface swim back to shore. Much more time was spent in the sand. They got all excited when they saw some skates and skate eggs. I used natural navigation to get us back to shore...we ended up pretty close to where I thought we were, too!

Second dive, 42 minutes, 40fsw.

We loaded up and were gone by 1pm. Wonderful day. Then my beautiful, wonderful, sweet girlfriend took me out to Legal Seafood for dinner. Mmmmm...............I ate all the things that I had seen earlier in the day.

On the first dive we went out on a 30-40 degree heading and I came across a huge, mostly symmetrical "pyramid" underwater that looked somewhat man-made. It even had a bit of a dug moat around it. Anyone seen it or have any idea what it is?

Sorry for such a long trip report, but it was a fun day and my first time ever leading a dive.
 
Aaron,
happy belated birthday. great trip report. sounds like you handled all the situations pretty well. I'm pretty sure the pyramid formation is the work of aliens. The same ones who form the crop circles.

question, why suck along surface itnerval 1.27, were you just resting up?

Well, by "surface" interval, I don't mean that we were actually out of the water the entire time. 20 minutes of that was a swim back, then we walked up to our gear on the grass, took our stuff off, chit-chatted, walked to my car which was parked 1/4 mile away, got some stuff out of it, walked back, realized that the fresh tanks were in my car, walked back to the car, drove the car to the beach, unloaded tanks, reloaded spent tanks into car, drove the car back, walked back to the beach, geared up, got in the water, swam out for 10 minutes...

The dives were kinda short for their relatively shallow depths, but part of that was unfamiliarity with LP tanks, plus current, plus I was concentrating on my compass more than my breathing. I ended up on the beach with 1000psi on the first dive and 700 on the second, but one of my buddies was down to 500. Chris, on the other hand, doesn't breath. He was only at 1200 on the first dive and 1000 on the second. Small lungs.
 
Happy Birthday and thanks for sharing your trip! Congrats on leading your first dive, gives a real boost of confidence doesn't it?

Thanks!

It definately boosts the confidence quite a bit. I was amazed at how much more I noticed underwater when I was responsible for the navigation and planning. One of the guys' depth gauge wasn't working correctly, so I also had to watch my computer closely to make sure we didn't break our depth limit (40 feet) for the dives. Admittedly, at that shallow depth, slipping into the next depth group wouldn't be a big deal, but as an exercise, it was important.
 
so I was it! It was my first real time navigating and I generally followed the shore but got adventurous and was surprised at how well I did. I am not sure about some aspects of navigating and would love to hear some pointers.
 
The basics of navigation in an open space on a typical shore dive is pick a heading, head out on it, when you're ready to turn around follow the reciprocal heading back. But you already knew that. One important thing to keep track of is current - if it's present you gotta compensate for it. Say you're heading out on 180. At the start of your dive you stop and notice that you're drifting to the right a bit. If you want to stay on 180, you need to compensate for it and swim on say a 165-175 heading, depending on the speed of the current. When you're ready to turn around, you swim back on the 005-015 heading instead of straight North, once again compensating for current.

Another thing to worry about is if you swam out to some point prior to submerging and then headed out on a heading different than the heading of your surface swim. In this case, when you're coming back, you'll go right through the point where you submerged, and when you reach the shore you'll be somewhere other than the point of entry. Example - you swim out on 180 for 50 yards, submerge, and head SW. You're swimming along, enjoying the dive... You decide to turn around and head back on a reciprocal heading. As you're heading back, you finally reach the shore, but while on the reciprocal heading you went right through the point where you submerged and when you reach the shore, you're somewhere East of your point of entry. To adjust, on the way back weer a little towards the shore, no more than 5 degrees or so, and you should surface somewhere near the point where you entered the water.

Of course, navigating along a wall or shore is always the easiest. Hope this helps!

How to account for current was really the core of my question. Thanks, seems pretty much common sence but wasn't sure if there was a formula or if it is just guesstimation.

The classic method of dealing with current is to swim out on your course, turn and swim back on your course. You will have actually done two sides of a triangle. You then turn and swim directly into the current to your starting point.

The best method if your going to head out and back on the same line is to pay more attention to specific things than to the compass, using your compass only to make sure you're heading in a straight line. Then when you swim back, you use both the compass bearing as well as the natural navigation.

Of course, the navigation dive in your AOW course will help quite a bit with the basics...
 
And remember some of the best natural navigation on a shore dive....

1) You'll be getting shallower on the way in
2) The ripples in the sand run parallel to shore.

The last two dives I've done, I put my compass away when I hit the sand and just followed the ripples in.
