i don't mean "get away" as in escape... just that if you deploy from any depth (I normally deploy from around 35 or 40 feet) as I ascend, the horizontal distance between me and the SMB can increase - and I'll let it go. as I ascend, yes, I reel in the line, but at safety stop I would prefer to remain with the group as opposed to being slave to the SMB... so again, I let it go. Reel in as I make the final ascent.

I have no idea what you are talking about. Why would you let it go? Why would people have trouble staying with you when you are shallow? The biggest problem with the float puller getting separated from everyone else is when the surface current is much faster than deep, so the DM is pulled along through the slower bottom currents. Once you get to 30 feet, the current should be pretty much uniform.

Sounds like your experience differs from mine. current is not "pretty much uniform." I wouldn't say that people have trouble staying with me... but i'm normally diving with students and they deserve my attention, rather than having me try to hurry them along if the float is going faster than we are. That's all.
 
Sounds like your experience differs from mine. current is not "pretty much uniform" but that's fine, you do it your way, and I will continue to not tow a float. We'll be fine.

I'm not suggesting that you must pull a float and I have described some very real disadvantages of doing so, but you don't seem to have a good grasp of what it is like to pull a float in a strong current. If given the opportunity, I will always let someone else pull the float, but I have done it many hundreds of times.

This video shows what our local diving is like with a strong current.. I screw up and drop the reel and sometimes the float even gets pulled under if you stop.. These conditions are more extreme then the dives I did in Cozumel when I visited on two trips..

I'm out for now. Going diving. Thanks for the chat.
 
Towing a float in a strong current is practical in many locations. It is best if it is a streamlined float(s) and a reel with thin, strong line is used to minimize drag.

I love floats!

I always give the float to the "fast" diver. It makes for a much more enjoyable dive. 8-)
 
I'm with Kari on this. There are many reasons that DMs don't pull a float, not the least of which is that they would be unable to enter or exit any of the swim-throughs. It would also make it EXTREMELY difficult for them to look at things, stop, point out things to divers, photographers etc. etc. without being dragged away. At depth, the risk of entanglement in the reefs above is also problematic. All in all, simply not practical in Cozumel as we dive there.

I've spent two weeks diving with Paradise Divers, and from a professional POV, they seemed to take reasonable precautions save for not pulling a dive flag on each and every dive. That's something that none of the boats do down there and I wish they would rethink it. A dive flag on the surface would have alerted surface support to the imminent problem of going near the channel. They could have easily given a couple of good pulls on the flag to alert the DM that they needed to surface earlier, rather than later. In fact, there are a number of incidents that would be averted in Coz if they only towed a dive flag. Unfortunately, that would stop them from doing any swim throughs and I doubt they would be willing to forgo those.
 
I personally would not be able to dive in some of the currents here (Laamu Atoll, Maldives)if I was also towing a float. It can take real effort with an inflated SMB at the SS to keep from being pulled away from other divers.
 
I just got back from a week of diving in Cozumel with the dive operation: Dive Paradise. We did not have a good experience with this operation, for several reasons. One of which I will report here.

The final day of our trip, we did three dives with Dive Paradise - the final dive tallied 14 dives total for the trip. The boat left dock at about 3:00 pm and took us to Paradise Reef: our dive plan was to dive Paradise Wall for half the dive, then Paradise Shallows for the second half. Paradise Wall is deeper and further from shore. Paradise Shallow tracks directly into the cruise ship lane.

When we jumped into the water, the current was extremely strong, but the dive proceeded as planned. About 30 minutes into the dive, we arrived at what appeared to be a mooring line - a chain extended to the surface on a buoy: we had obviously come close to the cruise ship docks, though none of the divers realized this at the time. The guide had the perfectly safe option of ascending for our planned 3 to 5 minute safety stop on the mooring line, but instead chose to direct the group of six into the current (an impossible feat... and at least one of the divers had less than 1000psi remaining in his tank at the time), then rapidly ascended from approximately 60' to 20' at a rate far too fast for safety. All six divers chose to ascend more slowly not realizing the danger because we were not briefed on procedures if we came near the cruise ship lane. The guide continued to the surface with his SMB deployed. All divers initially attempted to complete a safety stop. It wasn't until another diver realized how near we were to the cruise ship lane (by the sound of the ship) that the group understood the danger and surfaced. Upon surfacing, the group was approximately 100-150m from a cruise ship that was powering up to leave port. The current was pulling the group directly and quickly toward the ship.

Three divers and the guide were permitted to climb on board the dive boat (one of the small 'fast' boats). The remaining three divers were asked to hang onto the side of the boat as the captain powered up the twin engines and drove quickly away from the cruise ship area. During this ride, at least one of the divers' head was underwater, though he fortunately had the presence of mind to keep his regulator in his mouth.

When all remaining divers were on board, the guide never once asked if the group was ok. He was more worried about receiving a fine for being too close to the cruise ship area, and indicated this by asking: "Did anyone hear them call harbour patrol". Nobody on the boat was able to complete a safety stop: each diver had between 1 - 2 minutes remaining on their 3 minute safety stop when we were forced to the surface.

So the questions are:
- When the guide realized the speed of the current, why did he choose still to take the group to the shallower area of the site that would take us into the cruise ship lane?
- Or, why did he take us to this site at all - being an experienced guide he should know the approximate cruise ship schedule and know to avoid the area.
- When we reached the mooring line, why did he not choose to ascend along the line instead of cutting back against the current and being pulled closer to the cruise ship
- Finally: the cruise ship will not leave until the pilot ship gives permission: why was the decision made to make 3 divers hang off the side of the boat while under power? This only adds to the potential of injury if someone lost grip and fell into the twin motors.

We were extremely unhappy with the service and experience we were subjected to at Dive Paradise in Cozumel, and will not recommend this operation to anyone in the future. The staff with few exceptions are unfriendly, arrogant, and extremely poor decision makers. Avoid this shop if possible.

I am a South Texas diver. I dive the Port Aransas Jetties in near zero viz with ships from the 7th largest port in America going back and forth pulling me into the ship channel. It's a narrow channel with ripping currents often made worse by the ships. I have dived there all my life.

I have dived with Dive Paradise and near the cruise ships many times without any incidents crystal clear water. This is great operation and they do a lot o fbusiness.

I don't see any way someone could not be aware of he cruise ships whether they were specifically briefed or not and if these divers were on a six pack "fast boat" they all should have been advanced divers capable of safely communicating with the DM and aborting the safety stop if he or they sensed danger.

I don't think based on my experience around ships and currents that there really was any great danger, but a situation that could quickly have turned bad.

Sounds like a power struggle between the divers and DM/Dive Op to me.

PI just can't believe I read the whole thread...

There is also the problem of surface currents often being faster (sometimes much faster) than currents at depth within the reef structure. DM would have to work like hell just to keep his line clear and divers would be swimming pretty hard to keep up.
