Actually no, Halmyr, I keep my hands out in front of me as I swim out. I just don't move them around as if I were doing the breaststroke. I noticed that when I did try to stroke with one arm of the upper body(the other arm was out front holding onto the dive line) that I was feeling the cold water "replenishing itself". Granted I don't use the arms after I initially get into the head down position, even though I am diving no fin. I just do the breaststroke kick with the legs and leave both arm pointing at the bottom. I may be wrong but this does seem to optimize the stroke, err make it more efficent and use less energy. I may be wrong on this idea but it does seem to work for me. I am only diving down 8-9 meters at the present time, trying to stay in the warmer water at the surface.
Amazing the difference one meter can make in terms of water temperature. The first dive today was in 7.5 meter deep water. Upon surfacing, before my head even broke the surface I was realizing that I hadn't seen any kind of drop in the water temperature down at the bottom. I moved out a little further between dives and was in 8-8.5 meter deep water. On the second dive I did notice the drop in temperature from 17.5-12.5 C. Incredible the difference one meter can make. Admittedly, from what I've been told around here thermocline is generally around 7-8 C so I wasn't at thermocline yet but the temperature drop does seem like it has remained at a constant level over the past several weeks. Today was the first time I have really noticed the depth at which the temperature dropped. Heck, maybe I am starting to get used to being underwater once again, LOL!!!
Next time I'm out I'll have to try the idea of keeping the arms at the side while on the swim out and see if it makes any difference or not. I agree it should make a difference. It might make swimming out a little harder as well.
