We moved up from a 30' Chaparral Signature 300 to a 2010 Sea Ray 450 Sundancer. Our Chaparral had a canvas Bimini top and front, side and aft canvas/isinglass panels. Although we live in Seattle, it still gets quite hot in the summer and in the past I have even gotten heat stroke when we cruised all day with the Bimini top down. Over time we realized that even if we took most of the canvas off, I needed the Bimini top to stay up to protect me from the sun. Over time as the boat got older and the isinglass panels started deteriorating, we were having issues with trying to cruise when it was raining because we would get pelted in the face with wind and rain where the isinglass panels met the windshield.
Now with the Sea Ray with a fully enclosed hard top and windshield, it's like night and day. When it's hot, we can either open the front vents and let air flow through the cabin or we can run the generator and turn on the AC. When it's cold out, we run the gen and run the heat. We're always comfortable now and it's almost like a different type of boating. Previously we felt like we were roughing it - more like camping in our 30'. In the new boat it's pure luxury and comfort. At this point and with our previous experience we would not consider going back to a boat without a hard top and enclosed windshield. If you really want the experience of running with the wind/sun, etc, then get a runabout to do that but for longer range cruising, we absolutely love our 450 for the comfort, the practicality, the look and style of it. We also have a sunroof (sky hatch) which we can use when it's not too hot.
Best of luck in your search! There are a few 450 DAs available in your area. If it's in your budget, I highly recommend this layout. The cockpit and salon are so well designed and the living space feels very open with tons of storage. Feel free to PM me if you need more information on our boat!
