AgreeBut the legs and arms positions affect the trim significantly.
That's an interesting note.My ideal trim is perfectly horizontal, with straight knees and ankles and with arms along the body.
...
My trim is aimed to maximum speed against strong current in open water, such as channels in the reef (Maldives) or places with strong currents in the Mediterranean, or internal rivers.
For such purpose you need long free diving fins and a very efficient flutter kicking technique. If you flex your knees you will never reach the required thrust and speed...
I dive in the Mediterranean sea too (you know), but still I mostly like to dive close to the seabed to inspect small creatures without disrupting their habitat; so I'd like to stay close but feet up, steady and ready to back away. So, I tend not to dive with strong currents.
But it did happen sometimes and it was fun too ... and I totally agree, flutter kicking with straight legs made the difference, trying to frog kick against strong current was a pain in the ass and not that much efficient at all :-( I'm still not good at that anyway ...
Tell me more about it, I'm curiousMy ideal trim requires placement of buoyancy and weights different than the placement which provides the trim of your drawing...
