Smack,
When hit by a breaking wave in really nasty conditions, it will NOT be confined to the aft or the bow of the boat. It will probably also be a freak that comes from an unexpected direction, thus you might take it in the cockpit when using a chute (or viceversa). The weakest point on many yachts are the cabin, and a breaking wave that smashes the cabin top is going to ruin your day
Talking about strenght, the bow and deck structure in the fore-triangle will probably be a little stronger than the cockpit, and the cockpit will contain a lot of water, but if you have a moderate size cockpit with a bridgedeck the difference should be negligible?
You MUST avoid breaking waves, and the JSD is probably the best device, yet, to ensure that. In non-breaking conditions a chute might be great, especially if you want to avoid a lee shore.
If you read Adlard Coles (my copy is rather old) there's evidence of streaming warps and using chutes, with no clear conclusion on what works. IIRC his conclusion were that "it depends" however many of the chutes broke their attachment points and lines. This is another thing that I do not like about chutes, the MASSIVE forces that they apply to the vessel, which the JSD or toher warps do not do to the same extent.
