Hello all!
Since this is my first post here, some introduction before the question. I've been a SCUBA diver for three years, have 57 dives, of those 32 this season and plan to do around 10 more (I'm hooked ) I got CMAS P1 two years ago, PADI AOWD last year and will be completing deep diver and rescue diver this month. I plan to dive for a bit to see where my ambitions will lead me before taking further classes.
For the last few dives I've been trying to set my trim. My goal is to be as stable as possible in any position. With the standard BCD I can be stationary in a lot of positions but as soon as my front faces up I'm pulled into face up position. If I got this right it's because the air flows to the front part of the bladder and the centre of buoyant force shifts towards the belly, thus increasing the distance between centre of gravity and so increasing the stability of the position - an undesired effect.
As I understand the working of a BP/W this should not be such an issue as the bladder does not move as much - the smaller the bladder the less of movement it makes. Am I correct?
If so, is it possible (and how) to trim a BP/W the way that I'd like it? I will be trying out a plastic BP/W this weekend and would appreciate some hints about the position of the 10kg of weights.
TIA,
Jan
