All good advice except at least here in MN NADA values are indescribably inappropriate and bold faced lies at least for bowriders. The NADA values are so low you'd get laughed out the door if you tried basing any cogent argument from them. Everything from cars to boats costs more up here and so my region may be very different than yours. The value is simply what you are willing to pay. The fact is the SX series is a very entry level boat but most I have seen generally come with the 5.0 which is nice. I see many early 2000's models here for sale at any given time. If my quick glance is correct that 19 foot boat weighs just over 2000 lbs plus a bit more with the v8. That is hands down the lightest 19 footer I've ever seen meaning a rougher ride for that open water use you mentioned. A light hull is punishing but fast on top end. In general, with a broad brush, the heavier the boat the more expensive it is. Start with Cobalt and Chaparral dry weights and move down the scale and there is almost a perfect correlation of price to weight (and also gas tank size to price as well). This is a little less true with the contemporary boats out there as even Bayliner has caught up. My point being if you are going to shell out the $, get a heavier 19 foot hull for a better ride. My 18 foot boat with only a v6 weighs almost 1000lbs more than your 19 foot target boat. At least here you see the heavier hulls on the bigger water because they handle it better. Just my 2 cents.
