Currently the club that I am part of don't seem to be too concerned about
the safety aspects of using the correct weak links for winch launching
and I'd like to know how safe it is.

Currently I see two issues with the winch launching:

1. Sometimes a weak link is not used at all. The gliders are attached
directly to the winch cable (via drogue chute and various connectors).

2. When a weak link is included in the cable (only a primary link - no
reserve link) it is used for all glider types (G102 Astir, G103 Twin II,
ASW20, LS4) and I'm not even sure what the breaking strain is. My guess
is it's a Tost #1 black (1000 daN) weak link but that's hard to tell
because its weathered and the protective sleeve obscures the Tost number.
The weak link is never changed between glider types.

According to what I have read (glider manuals and Tost manual) the
maximum winch load that should be exerted on most of the single seaters
is 500 daN and on the G103 Twin II it's 750 daN.

Am I being paranoid about safety? Are weak links not that important for
safe winch launching?

I took the matter up with the safety officer who said I need to take it
up with the CFI but I'd like to get some advice and input before I engage
with the CFI over the matter.
I'm new to soaring so I don't know it all.

Thanks

Scary. I fly in the UK, we always use a weak link, what strength to
use is stated by the BGA:

As it shows, the black weak link is OK for the glass two-seaters but
not the single-seaters. (sorry it includes some Skylaunch stuff as
well)

BTW we never use a backup weak link - if you rig it so it doesn't take
a shock load when the main one fails then it will be taking strain
itself and so makes the weak link too strong, if you rig it so it's
not taking any strain then the shock load is likely to make it fail as
well.
