My rationale for the maintenance of a donned snorkel is:
1. BC malfunction when donning buoyant gear. It will force you to ditch your weight due to the heavy lead you have on.
I've never seen a BC malfunction. Ever. Not once. Even with ratty, old rental gear.
2. Make you a better buddy - when your buddy is in trouble, it helps you to have better visibility at the surface to help him (without using your regulator).
How does a snorkel help with this? Please explain. I've helped my buddy plenty of times, at the surface, without having my reg in my mouth, or a snorkel. I would think, that in a buddy-in-trouble situation, the rescuer would be more in danger of being shoved under and inhaling water through a snorkel.
3. Save lives - especially with anxious beginner, or those who have weak swimming abilities. Enough anxiety already at the surface, add a few foot of waves, and they will panic. A snorkel will remove the need to gasp for air, and take away anxiety. These are the folks that will also have an empty tank.
Generally, such anxiety can be mitigated by approaching the person calmly, having them turn onto their back, and having them just take some long, slow breaths. As a newbie, they are going to blow through their air anyway. A snorkel isn't going to make or break them in this situation.
4. The safety aspect outweights the "stream line" benefit of not wearing a snorkel.
Really? The snorkel, as I see it, is an entanglement hazard. My own experience, on my OW cert. dives, was jumping in and having my snorkel rotate on the mask strap, preventing my mask from sealing and giving me a noseful of saltwater. I couldn't see why my mask wasn't sealing, didn't know my snorkel had rotated, and all I really knew was that I was having a serious problem. My buddy came over and fixed it for me, and after the dive, told me what had happened. Wordlessly, I took my snorkel off and thew it my boat bag.
5. One can swim better with scuba on if one had a snorkel..
Really? Please elaborate on this. I'm interested.
