I really enjoy night jumps, but I usually use a different canopy.

Your normal canopy with a higher wing loading is fine, IF you are going to land where the lights are and thus have some depth perception. However, several years ago I was on a night jump at the Richmond boogie and there was no moon that night. They were supposed to have lights in the landing area. But, we were the first group out and they hadn't gotten the lights there yet. I flared when my feet hit. Not good. One of the guys in our group broke his leg, and two of the others (me included) were limping the next day.

From then on, I use my demo canopy -- a PD 253 -- which I could land nicely in half brakes in case I ever find myself in a no light situation again, whether it's due to a poor spot, changing wind conditions, or anything else.

That safety factor is far from illusory. A canopy that will not spin up on opening can be a big issue when you can't see what's going on. A canopy that will land you safely in bushes at half brakes is much better than one that you need to flare perfectly to survive the landing, since you may be landing off the DZ with no way to see anything.

Ask yourself if you could land the canopy you have by going to half brakes at 50 feet and PLF'ing. If not, it's not a good choice for a night jump.

My regular Sabre loaded about 1.3.

P.S: One of the major concerns that people express about night jumps is loosing a main in case of malfunction and cutaway. I recently talked to one of my buddies and he had this idea about having some kind of bug transmitting a radio signals hooked to main canopy. Such device should help to find a chopped main. It would be interesting to know what dz.com community think about it.

I totally agree with Bill here (now), but I think you should take it one step further. Ask yourself those same questions about your reserve also. I trusted my main, but didn't know my reserve's flight characteristics. Lesson learned.
I would have no problem jumping my Sabre 150 or my old Sabre 135 at night, and even attempted it. After a hard pull, I ended up with a PD126R, which I have now figured out I loaded at about 1.6 to 1. Bad move. Very bad move. I lucked out, plain and simple.

Seriously, when thinking about these jumps, take your entire system into consideration, not just your main.
It's your life, live it!

The best I've heard.

Words to live by on any jump!



So true. I´ve just recently started using weights (4 kg). I´m ok with that on a lightning 126 (it´s for WL purposes, obviously).
If I want to jump with weights in freefall tho, I´d be ok with my spectre 135 or safire 135, but with my 128 sqft reserve... dunno. I´m already loading it at ~1.2.....
The reserve in the CreW rig BTW is 175 sqft.
