Glad to help, that's what's great about these forums. We had our 320 for 12 years and loved the boat. However, as you point out one of the reasons we knew we would be moving on was due to the sleeping arrangement. We spend up to 2 months a season sleeping on our boats and the forward berth was not comfortable and we were tired over the somersault exercise in the aft cabin. The 320 is actually something like 32' 6", but I don't recall.Thank You Greatly, I am interested in the 310 for the reason I think most 310 owners are- the livability for a couple. I went to my broker who I have a good history over the years. I want a local 310 and not one from other regions. Many reasons for this position- mainly East Coast boats tend to have shallow keels for their cruising grounds as I prefer Deep keel. There are other reasons I wont get into now. You mention the 320- I have not been on one but discovered Catalina built many more and their are two versions. The 320 is misleading to me as I looked at its dimensions and if I recall it is actually 34 feet? Again their was also a C34mk2 being built as well. I suppose you liked your 320 and am sure it has pro's and con's. I actually would not want a 320 as we prefer sleeping forward. Again the 310 only being 31 feet seems to be the best couples boat for coastal cruising. As I stated earlier post- I am sad this model was discontinued Thank You for clearing up the 5 series. I have not seen the 315 in person. My broker and dealer does not have any in stock at present. To order one now would mean I would be lucky to get it by July. I am taking the position of holding out for a 310. The 355 as you have is very nice. Dealer just sold one. There is a price jump between boats as I mentioned earlier about 58K. One reason I am holding out for a 310. The price jump was between 315 & 355 base boat. Since the CP on 5 series is embedded in fiber glass hull I would think it would be hard to inspect and maintain. I was led to believe by Warren Pandy that you don't!! Again, Thanks a bunch!
As to your question of why builders don't use Butyl, Gerry was quoted in Practical Sailor a few months ago saying he has been using it for years on his boat...he just doesn't say where
