A few thoughts from a steel boat... I've 50 x 50 x 5 @400mm long stainless angle welded to the deck/hull with about 50mm cantilever past the transom so comfortable with that. Hard to find any figuyes to calc but 700mm of weld in sheer ain't gonna go anywhere I reckon. Moving back and thknking a bit after this thread the 5mm angle seems a bit thin for a shackle pin, probably weld some plate on there though getting a hole drilled big enough for a 5/8" 209 crosby bow shackle might be a bit of a pain. 16mm would be ok with 18v cordless for a 2t crosby but 3 - 1/4t might take a moment. Anyone saying "you're overthinking this" isn't going anywhere and doesn't understand huge forces. If going to the bother of installing something for a JSD then might as well do it bulletproof. Then think the bridle legs which came with the drogue will get ditched in favour of some monstrous dyneema which arrived after a red wine incident on ebay Bridle node likely 2 x 3-3/t shax into a 4-3/4t shack or a master link. Forget low friction rings etc, these sorts of potential loads the local crane supplies is where you should be shopping.
Maybe of greater concern is keeping it above the windvane, thinking a handful of fish floats in the bridles. Seems pretty common for a jsd to trash a windvane paddle though not so common to find out exactly what happened. As this is all to try and push the odds more in your favour seems a handful of floats would be a step forward .. All this for something which might well never get used. But it might, and it might be serious...
