Just finished reading 'Storm Tactics' and it was a good read. The 'catch' is, it doesn't really talk about catamarans all that much. It mentions that some people like to sea anchor bow to the wind via a chute but that isn't heaving to. It mentions sizing for average 35-40 footers being 28 foot
- which seems gargantuan since it mentions 18 feet for 56-80 foot monohull. They also say 'will generally lie well' at this part; which I am not sure means lie well hove to or lie well bow pointed into the wind.
So, some questions...
1) Do cats heave to well?
It depends on the specific cat and the conditions.
2) Does the second hull aid in making the slick larger or more stable?
3) Does the lack of a deep keel hinder the creation of a slick
Yes, it probably does, as most cats will have a shallow enough draft that they don't get deep enough to create a very effective "slick".
4) How do you rig a para anchor for a cat - it would seem to need to be off the anchor fittings at the bow but that is in the center of the front section; would make lines going across the windward hull potentially a problem no?
I'm not a big fan of the parachute type sea anchors and think that a Jordan Series Drogue is a much better choice of survival gear to deploy as it doesn't require you to go forward in crappy weather... and doesn't strain the boat as much as a parachute does. In either case, the parachute sea anchor or Jordan series drogue should be attached via a bridle that is at least 1.5 times the length of the beam of the boat, and secured to dedicated chainplates on each hull. It would be from the bow for the parachute sea anchor and from the stern for the Jordan Series Drogue.
5) What do you lead your penant rope back to - a winch directly or a round it to a cleat and into the winch (this was not clear in the book); would a cleat not be a huge source of chafe?
Are you talking about the pennant rope that is lead back to hold the parachute sea anchor at an angle to the boat???
6) How big a para anchor would one be looking at for 45-49 foot cats?
Depends on the design and displacement of the cat.
7) Would the heave to motion be more uncomfortable in a cat compared to a mono?
Sorry for the newb questions but thats what I am hehe.
For some people the motion of a multihull, which is quicker, is less comfortable, for others it is more comfortable.

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.
