Hobie's stance is that they're mostly cosmetic, but they seem pretty significant to me. I think your answer is going ot be a huge "depends", because you're dealing with fracturing/failure of plastic. Unlike most fiberglass, most plastics SEEM to be more sensitive to UV exposure. Add to that how hard the boat is punished and I think you have actually a combination of factors that dictate if/when the plastic cracks. I do not know if it is "inevitable", or whether it has to do more with cyclic loading or age+loading. Seems some people are having some luck with repairing the cracks with G-flex epoxy, I think it is. They can not be welded very successfully though like other plastics.
All that to say - just because it doesn't have cracks YET in no way does it mean you won't get them, nor are you doomed to get them. I've watched them for a few years, and it appears even after getting some cracks they seem to be quite servicable for a while, meaning I'd shop for one, preferably without cracks and buy it with the understanding I may need to do repairs in the future, but definitely don't sweat it.
