Is there a website or place to gather sales data for catamarans? For houses, for example, there is Zillow.
I am thinking these items will determine the price
1) production year of the cat
2) cat maker/model
3) cat size (may be part of cat maker/model)
4) location/region of sale
of upgrades (though highly doubtful there is structured data showing when and what was replaced/upgraded, so this is likely a case by case basis issue)
#1-4 are likely the easiest to get while #5 may not be available at all.
Are there any other variables that would generally impact the sale/purchase price
of a cat?
