It depends on which HP boats you are looking at. I dont think there is enough volume in some of the builders to get accurate averages. What is standard in an offshore boat? There are also allot of pricey mods out there that I would never want or pay for. Kinda the way some home buyers see a swimming pool as a hazard, not a 60K+ add on like the seller.
I would narrow your search to 2 or 3 boats and figure out what is the best value to you.
Thats about the only way Ive been able to figure it.
