I have only used it once and was greatfull for the rest it gave us there seened to be little if any shock loading as the rode was 1" white polypropoline ( I think that was what it was ) the whole thing fitted in to a easy to store bag. No where near the size of the JSD bulk, and I feel that would be the only down side of the JSD. There is a number of drogues on the market that take up less room, just my opinion.
Yes, a JSD may be quite bulky, but I believe that it is more effective than the other drogues, which do not have the distributed load design of the JSD. All the other drogues need to be adjusted to the match the distance between waves, to keep them "positioned" properly.

A JSD requires no such adjustment. As Don Jordan has said, it is kind of like an ejection seat for sailors, just drop it in the water and then hunker down below and hang on. There is no need to adjust the JSD for different wave conditions, as it is designed to self-adjust effectively.

The only real danger with it is the bridle for it chafing through, and if the bridle is properly designed and attached, chafe will be minimal. Chafe is a huge issue for parachute sea anchors and many of the other drogues, since the loads they generate are far more variable and larger.

BTW, you shouldn't use Polypropylene for any kind of sea anchor or drogue line, since it is by far the weakest of all the synthetic lines and also has some of the worst chafe, heat and stress resistances of any kind of line. Storm drogue and sea anchor lines need to be made of nylon IMHO... as they need to have the stretch that only nylon really provides.

One thing I will say about the JSD... retrieval of it sucks... it is a royal and complete PITA. Most other drogues, and I have used the GaleRider and another one, and the parachute-type sea anchors...are relatively simple to retreive in comparison.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
