Yes, I also followed through with the Mahina summaries, wikipedia, and a good dig through the back and forth arguments on boatdesign forum.
Ideal is either a deeper modified(cutaway) full keep vs a shallower heavily built fin( like the CS 36 with shoal draft) I also noted as a negative in my notes the deep draft fin on the CS33.
The deep draft is an asset until I screw up
So it is not a deal breaker for me, but rather something to be cautious about, and definitely a factor to consider.
Likewise with the full keel on the True North 34, it is at the far end of my desired attributes(ideal is in the middle between the two).
I'm trying to keep an open mind though, a deep fin means a bit more speed, but more risk. Within reason either is acceptable, just not ideal, my ideal is the balance between the two, which I(correctly nor not) believe to exist within my budget on either a heavily built long shoal draft fin or a modern cutaway full keel.
My ideal would one of the twin keel designs that could equally happily sit on the beach as sail. Or even something like the Hogfish Maximus if it wouldn't handle so terribly offshore. Budget and reality constraints apply however.
I even like the idea of ferrocement(the flexible and ultra durable high end versions, not the home built crap.)
Not so much this kind though.
TQA: Little too big for me, though I have always had a soft spot for ferro-cement, my dad would never agree to it. I asked about a cement boat when I was little and we were sailing out from the RVYC. He had rather strong opinions on them.
Putting a True North 34 and a CS 33 on the same wish list just doesn't make sense.. you need to first figure out what kind of boat you want. Have you read the 'full keel vs fin keel' threads? Some homework there so that you can start comparing oranges with oranges.
I'm surprised to see so many CS33s listed locally.. they are usually rare as hens' teeth. While I'd be a bit leery of the low priced one, it's worth a cautious look for sure. If the other one has $10K worth on goodies/features it may be the better long term choice. I like these boats, esp for single or one couple accommodation. They are not well set up for guests. Great reputation for soild build, decent performers. Around here the deep draft is not a problem, but an asset. I'm sure a good, well prepared one will do just fine offshore.
The Aloha 32 is a 'shippy' looking cruiser from a good designer, Mark Ellis, it's essentially a mini Niagara 35, along with the unconventional layout of her big sister. Again a decent single couple's boat, robust long fin and spade rudder at least she'll be able to get out of her own way!
The Niagara 31 is a sleeper performer.. A German Frers design hidden under the cruisey look of the Aloha/Niagara style. Another layout not ideal for many guests, but sounds like that's not going to be a problem for you as a single liveaboard/couple.
Personally I'd be looking at these above rather than the heavy full keeled boats, even for ocean passages, but that's a personal subjective choice. One you need to make before you start to shop....
