Re: [skypuppy] Skydiving VS. BASE gear at Bridge Day?
Here are my views on the skydiving gear vs. BASE gear at Bridge Day issue.
BASE gear is ideal.
Appropriate skydiving gear can be jumped safely at this bridge if configured and packed correctly for a BASE jump.
There were 100 first time BASE jumpers at BD this year and similar numbers at previous years. These first timers are just getting into BASE or trying it out. Bridge Day has definitely helped this sport grow through the many years by allowing first timers to jump. BD is the one place on earth where this works. The span, the altitude, the water, the boats, the rescue crews and the ambulances.
Many of the people jumping skydiving gear are first-timers or low-timers. A lot of the ugliness you see from skydiving gear is because of poor performance by the jumper either during the jump, while packing the chute, or both.
Here are some specifics on using skydiving gear for a BASE jump.
1. A 9 foot bridle and a BASE specific pilot chute are required because if you do not get the stuff out of the container in a timely manner, that would be bad. People have died in this sport by not having these basic essentials.
2. A docile 7-cell canopy is way safer than a 9-cell or high performance canopy. The higher the aspect ratio of the canopy the more chance there is of it spinning up on opening. I have noticed that 9-cells do go into line-twist more often than 7-cells. Also, it is nice to have a big 7-cell while landing in a tight area. Jumping a cross-braced or similar high performance canopy can be fatal because that thing will most likely line-twist up and one turn of that canopy (either intentional or not) can cause an enormous amount of altitude loss. Please DO NOT jump a high performance canopy at Bridge Day.
3. D-bags can be a problem. They increase the chance of line twist and a bag-lock malfunction is very possible. The main problem with d-bags are the rubber band stows. Anyone who has been skydiving for a while knows that bag-locks do happen. The rubber band stows hang-up (get tangled) sometimes, typically due to sloppy packing. Also, as the lines pull out of the stows, the d-bag gets jerked around and often results in off-headings and line-twist. There is such a thing as a BASE specific sleeve (Mark Hewitt was working on one a while back). The important difference is that the sleeve does not use rubber band stows. Instead you s-fold the lines into a pocket like you would on a reserve free-bag. If I were to jump a skydiving rig at BD I would free-pack it if I did not have a sleeve. If you are planning on jumping a d-bag, make sure the stows are NEAT and SMALL (not too much line-stow hanging out)(Like a rigger would do on the diaper of a round reserve). I recommend you find someone at the Holiday Inn before BD who knows how to show you the method of free-packing.
4. Packing! Do not pack like you are just going for another skydive. While skydiving I can trash pack with the best of them, but in BASE your main is your reserve and should be packed that way. Make sure there is NOT too much tension on the closing pin. The airspeeds involve at BD are much less than a skydive.
5. If you are jumping slider up, then use a mesh slider. You can die from sniveling into the water. Do not let it be you.
6. If you are jumping slider down, make sure you understand and use the line-mod and a tailgate. This takes only a few minutes to learn and set up and can definitely save your life.
Through the years, Bridge Day has been a cool situation where skydivers can go to dabble in our sport and often end up becoming full-blown BASE jumpers. Though there may be pros and cons to this, it has helped our sport grow in a positive way. We as a community need to continue to assist these saplings at BD and welcome them into our family so that they will listen, learn, and not get hurt.
If you are planning on making your first jump at BD, make sure you get some instruction. Also make sure your gear is totally dialed in. Nowadays there is no need or reason to learn the way I did. Scary stuff, let me tell you.
Have fun, don't die!
