1. I cannot imagine how anyone would compare a 34 or a 36 to a 375. They are so totally different... I don't know why Catalina or anyone else says the 375 is a replacement for the 36.
2. The way I see it, the 350 and 375 are big brothers to the 310 and little brothers to the centerline 42.
3. Chances are, if you like the 309/320/340/36/387/400, you will not like the 350, 375 or the 310 and vise-versa.
I understand you keep asking about weight, but that's not all. Most Catalinas come in 10% overweight in reality compared to published data.
1. I agree completely. But Catalina said the 375 is the replacement for the 36 because that's their decision. Probably says so on their website, too. Don't ask me why, it's just a much better 350, as I noted in my earlier link to the C375 reviews.
2. No, because the 310 was designed for a specific purpose: two people cruising, smaller table. It's kinda a one of its kind idea and the owenrs who bought them to that purpose love them. Shares a hull with the old C30 IIRC. Neither the 350 or the 375 are little brothers to the 42. They have NOTHING in common with the 42, nor are they sisters other than the potential comparison of the layouts. The 350 is a large volume boat, the 375 is sleeker, much sleeker. Again, I refer you to the earlier review link.
3. Close but here's the comparisons we've received from our owners:
a. 309 (same as old C30), 310, 34, 36, C38 - old model, maybe 375, , 400, 470, 42, 445 - thse are "sailing" boats with interiors made for sailing
b. 350 - in a class by itself, a nice boat with a different purpose, 320, 380, 387, 389 series of 38s that Catalina made (the old C38 is a completely different boat)
c. 440 - is a liveaboard sailing boat, a completely different concept than all of the others
