All I received an email wanting to know more about the way I set up my crotch strap on my DIR rig. This may be of interest to others, so here is how I do it... Firstly, my crotch strap is made of 2" webbing - kinder on those most precious parts when scootering. The webbing is just slightly thinner than the thick stuff I use on my harness straps. A loop is formed at both ends of the crotch strap using single SS weight belt retainers for each loop. As this would be hard to explain, I hope it is obvious how you would form a loop by passing a double thickness of the webbing through a weight retainer. The weight belt retainer needs to be one of the straight varieties to take the double thickness of the webbing. (The straight varieties have wider gaps than the wavy weight belt retainers.) This weight belt retainer also holds the D-rings as per usual. The trick, apart from the slightly thinner webbing, is in getting the webbing onto the 1" ish slot in the backplate. I do this as the first step in rigging the crotch strap. First pass a thickness of webbing through the slot. To do this you must reduce the width of the webbing by folding both edges of the 2" webbing in on themselves to create a double thickness of 1" wide webbing. Thus creating a sort of letter "C" on its side. Pull this though ensuring the section in the slot remains as a "C" and does not fold asymmetrically. Once you have the right length of loop to correctly position the butt D-ring, then you can slip the webbing through the weight belt retainer adding the D-ring. In order to have the setup look good, I have the edges of the "C" innermost in the loop so that they are not visible. The double thickness of the webbing (the "C") in the slot will also act as re-enforcement in the event of abrasion from the slot, of which I have seen none. I scooter and have never had the arrangement slip as it is rock solid tight. True Hogarthian to my way of thinking: minimum equipment, multiple purposes for the same item (the weight belt retainer), and adjustable if necessary afterwards. Also, no damage to the webbing as would be the case with a bolt. Let me know if you have any questions. David Shimell Project Manager, Sequent Computer Systems Ltd., Sandton, South Africa.

"Shimellian". Hmmm, it has a nice sound to it. I'll leave now before my head is too large to get through the door. Ooops, too late :-).

The new wing (DR junior) and backplate worked out just fine, though I did bob along with my head in the sand for the first dive. Moving the bands a little further down the tanks sorted this completely. It was so much nicer not having to wear a weightbelt! I found I had plenty of lift for twins plus stage. I had no problems with getting in and out of the harness (deflating the wing just prior to doffing when using a chase boat is essential here, since the slack is taken up by the buoyancy of the wing). Your tip about not having the harness too tight was spot on. Also, I found the "Shimellian" crotch strap (using weight retainers instead of bolts) to be extremely stable and easy to adjust. The harness now just needs some of the extra webbing trimmed off.
