Re: EPIRB in bracket or ditch bag?

anyone contemplating a hydrostatic-release should read the literature about at what pressure they are designed to release. Mine was designed to release several meters below water (in other words, after I've sunk the boat and it's gone under).

I decided not to use the "float free" hydrostatic-release bracket. (My boat is an unsinkable multihull design that could have it hulls flooded but would never reach the depths needed to trigger release.) I keep it on a shelf, and it would float if we ever capsize.

Old.....

ACR ResQmate 406MHz EPIRB
ACR ResQmate Class 3 EPIRB

New.....

Of course we used to have a whole bunch of different Classes A, B, S, C & Inmarsat-E, but these are all obsolete and no longer recognised.....
I thought I read someone talking about the other categories, but maybe not. My mistake. I thought there was just the two, then manuel/automatic, GPS or not.

I thought 'float free' was different to a unit with a hydrostatic release?

No float free is a hydro static release

Re: EPIRB in bracket or ditch bag?

One hydro static release wherever you think is right on your boat so that it can be successfully and freely deployed if submerged plus one in the ditch bag plus at least two PLBs. All to be GPS enabled. Yes more expensive but...............
Just my thoughts.
