@betsy1561. Good to hear you're looking at the Hurricane. Very versatile boat and I've previously owned the smaller GS172 from 2002. Great boats.
As for price, that's really difficult to assess. Its driven by usage, area, and its condition
Try looking for similar boats in the area for comparison and also check here for estimates of ranges in price.
Hope this helps.
@betsy1561, as a former GS owner I never though about what the GS stands for. The SS is Sundeck Sport, the FD is the FunDeck but I have no idea what the GS stands for.
Perhaps @Capt_Steve will know or can find out.
However I'm guessing that since BOAT stands for Break Out Another Thousand that perhaps GS stands for a Grand Spent?
