Excellent point, new owners, of "powerful" excellent sailing catamarans, clearly need to understand how to properly handle this type of design.
Previous monohull experience, and or Bare-boat chartering a lagoon, or F.P. or similar heavy, mini keeled, under sail area powered, charter designed...
OK, that's a whole different animal. You really want the bridle, off the bows, out front of everything, if possible. You may have trouble back on the beam as the bridle may chaff on the hulls forward.
You would have allot of gear, you would need to clear or stabilize before you could do much of...
A sea anchor set off the bows of a cat, has a bridle, (The same way you would set a ground anchor on a cat)
On my cat, I would run large snatch blocks off the bow cleats, the bridle lines would run through the snatch blocks, down the side decks to the large spinnaker turning block in the back...
I'm just waiting for the actual story to come out..... and I'm sure we will get it soon enough..
Meanwhile the sideshow know it all's are just showing their lack of ocean sailing time.... especially when a multihull is involved.
Dismasted, Once the rig, standing rigging, and running rigging, is cleared away, and there are no problems with motors or props, motoring would be a first choice.
If you cannot move under control, due too no engines, or not able to jury rig a sail to do so.
In rough weather, the leeward board...
I'm not sure what your saying, its, well, incoherent.
But a serious offshore multihull is very comfortable in extreme conditions, perhaps you should try it some time, it will add to your ocean sailing experience, and up your seamanship, a few more notches.
Many multihull designs do fine offshore, Outremer, Crowther, Grainger, Gunboat, Catana, Schionning, etc, etc.
Unfortunately, many others are simply designed as "charter party boats", with a rig stuck on top of a power cat, and should probably not go offshore.
