Hello Drjay,
I think you have a good tight list. I arrived at a similar list of Cats in my search. My list came down to 5 cats: Hobie 16, Supercat 17, Dart 18, Taipan 4.9., Nacra 5.0 & Mystere 5.0. my cost goal was 2000. or less ( which in the end ruled out Taipan). Nacra 5.0 & Mystere 5.0 just were not available in the area at the time.
In the end I purchased a Dart 18 base on price, condition, location & extras. It was the best value of all the boats at the time so any of them were in the acceptable range.
Boat to boat, at 60yrs. I would consider weight and your ability to assemble, rig, launch and maneuver on beach, ramp or grass. It is best to be self sufficient but I have never met a sailor that would not lend a hand.
Boards or no boards? : one less thing to deal with. All boats on my list were boardless accept for the Taipan 4.9. You will not point as well until it's really blowing without boards. Of all the boats I researched boardless, the Supercat had the best opinions on pointing for boardless because the forward hulls are part of the lift design ( they called shared lift). H16 & Dart will point better in higher winds as you bring more of the sail balance back on the rudders, as the wind goes up, boat rises, you move back , more lift effect on less hull area and the more the rudders do the lifting. Super cat was the opposit, dig your bow in and you gained lift. This explains the big bows. I really wanted one.
Boom or no boom?: Clearly will be less painfull to be hit with a batten than a boom. Dart 18 & Supercat have no booms and people that have them like it. Again , one less thing to deal with, simplicity, no boom, no outhaul.
Weight: h16 - 320lbs. Supercat 17- 335lbs. Dart18- 285lbs. Dart is the easiest to maneuver dry by weight. I can handle my dart on my own with beach wheels and a launch ramp. 35lbs less than a H16.
Sail area: h16 - 218 sqft. Supercat 17- 234 sqft. Dart18- 175 sqft. Dart is light on the sail area so if you are in a light wind area , I would not recommend it unless your a beginner.

Extras..: cannot mention enough all the other stuff you need that adds up. Trailer, beach wheels, trapeze lines , trapeze harness, these all add up.
Parts availability: Hobie & Supercat are well supported Cat brands in the US still being manufactured. Dart 18 & Taipan you will need to look hard & out of the country. Dart18 is a large one design class in Europe but not in US. Used parts are harder to come by for Dart 18 & Taipan because they are not as common.
Dart 18 Shameless Plug: all of this said, I have only sailed 4 catamaran models: Prindle 18, Hobie 16, Dart 18 & Hobie wave. Of all of these, I like the dart the most and is currently what I own. Why? Simplicity. Lightest boat on my list for the cost without going to exotic materials. Great for 1 or 2 up. No boards to deal with, No boom , no out haul ...... you get it . I consider myself a beginner and this boat is a good match for my environment and needs. It carries a smaller sail plan which keeps it manageable (good winds where I live in RI so not an issue).
By Portsmouth ratings it is nearly as fast as a Hobie. I would argue at 15 20knts + of wind it will equal or take the hobie 16 with a more efficient Hull design and less weight. H16 D-PN: 76.0 Dart 18: D-PN76.3
I will add that the Hobie 16 is just one ugly boat to me . Two bananas held together by pipe fittings ( can't wait to hear from the hobie guys....). H16 designed in 1969, there have been advancements. Dart18, a Rodney March design from 1975 based on the Tornado class, still looks good today, big one design class in Europe.
H16 makes up for it shortfalls with lots of sail area. Also, Hobie sailors love them and if you want to race affordable, huge one design class and that is all that matters. Supercat & dart 18 have no large class representation.
goodluck, get that cat..... whichever one you decide on.
