Well, maybe "freediving" is not the right word, but this weekend, we invented a new game. We were grabbing large chunks of slate and using them for variable ballast dives. In one case, one of my buddies (who shall remain nameless, unless he wants to fess up) rocketed down using a rock that had to be about 35 kg. I think that we may post this profile soon.
The cool thing was that you could actually steer the rock and glide using your fins and the shape of the rock slab itself. Although this was really cool, we wanted more (being engineers and such).
So my question, to any aeronautically inclined DB fellow members, is whether it would be hard to build an underwater "luge/glider" that we could use to maximize our fun, and how would we go about designing it. We have access to stainless steel fabricating talent through two of our members, and it is pretty easy to get software that will generate a lot of standard foils if we need to create wings (I was thinking of NACA 0009 for this). We are hoping to make the sled in the 30kg range, so that we can carry it out on the water easily enough and power it up to the surface with a standard lift-bag or BC.
OK, thanks in advance for any replies
