waterproofing

Recommended Posts

just a random thought. i was thinking back to the fatality a while ago where it was thought that the reserve getting wet could of contributed to tension knots [correct me if ive remembered this wrongly].

i was wondering, would spraying something like goretex [waterproof stuff] on the reserve flaps etc work? or would the the spray itself be damaging to F111. or could a reserve container be made to be reasonably watertight [like an added layer of water proof material?].

im not a swooper, just wondering what other people thought.

sorry, meant the goretex spray you can buy. ive got some for my hiking boots. the water just rolls off.

really ?? isn't it just a spray which is goretex compatible (which does not degrade the fabric properties)

Most riggers would not pack a reserve in a container that had been treated with that. Not because it is known to cause problems, but because it is Not known to NOT cause problems. I would put it in the same category as dyeing a rig.

The cordura IS waterproof. But the spaces between the flaps aren't.;) Reserves don't get wet very fast but I understand that this jumper was in the water over her rig several times. (at least three, maybe more) There were other added considerations also.

PIA's position from the last technical committee: You can't pack a wet reserve (per FAR's) so why should you be able to jump one? We have no testing with wet reserves, no data to support using a wet reserve use, so PIA cannot support the use of a wet reserve.

But how wet is wet? Splashing through the shallow may be one thing. Standing in chin deep water may be another.

cheers for the replies.

here's another line of thought then.

assuming the main problem of the reserve getting wet is the lines. could you make [with materials/substances already in existence] the lines waterproof without degrading them?

this is ofcourse completely hypothetical and would i guess involve R&D and testing that i guess wont happen.

i was just thinking getting a reserve wet cant be good and well, if there was a real solution out there. (plus i love picking the brains of you experiences guys and riggers out there! :)

couldnt you just get a main canopy wet to different degrees and jump it 100 times and see what happens?

That would be a start, but you'd have to have the main be made of the same materials as the reserve, which means F-111 type fabric and different suspension lines.
