Can you convert a manual lifejacket to auto ?

[STATUE]

I know there are some lifejackets that are designed to do this.

But what I am enquiring about is, say, your bog standard Crewsaver, that was originally purchased as manual.

Can I convert to auto ?

Dunno about crewsaver, but my Plastimo life jackets use Hammar automatic release devises and they seem fairly flexible. I just bought two replacement units.

In theory you should be able to remove the current manual only firing mechanism and replace it with an auto mechanism. Given the comparatively low cost of new auto lifejackets, it probably not worthwhile.
