How do you compare them like for like?
We compare boats of the same build year. For each of the 5 years both models have boats in, we take the ratio of their median asking prices in today's prices, then pool the years, giving more weight to years with more boats on both sides. The figure is Indicative because the thinner side has 16 boats in those years.
