Re: performance questions
divesup,
For what it's worth, I'll drop in my two cents.
I am still considering the purchase of a GS279 and asked about a GS259 that my local Glastron dealer also had in stock (less deck space to carry people, but it was cheaper...so...I asked). His take on things was that the 279 would offer a better ride even in the Bay "Chop" (here in NJ, Barnegat, before even getting to the Ocean). Basically said the 279 gave a better ride (but he could also have been steering me towards the more expensive boat !).
I test drove a Crownline 250 over the weekend (more or less "in between" the 259 and 279) and in choppy bay seas... I was less than impressed (less deadrise than the Glastrons, but not by much). The Crownline dealer basically said something along the lines of "better ride in the bowrider over "chop" but better stability in the Cruiser when anchored and enjoying the day.
I've been boating for about 6 seasons now, so I wouldn't necessarily call myself a seasoned boater...yet.
But if you're asking about a Lake - where the waters are presumed to be mostly calm - I would assume even a 259 would be fine, as compared to any Tidal waters (I assume its not a Lake like Lake Michigan, for example).
I posted a couple of times here as well (see this Glastron forum) and those also went unanswered (frustrating and aggravating, to say the least, can't even get an opinion out of anyone, it seems). When I first found this forum, it looked promising...now, not so much, when I actually tried to use it. I'll keep trying, but it seems pretty dead here.
Good luck in your selection.
