We can't say yet. The Beneteau Oceanis 45 loses about 3.7% of its asking price a year of age, but the Jeanneau Sun Odyssey 509 has no published depreciation curve: we fit one from at least 20 boats across six build years and publish it only when the fit holds.

Which spends less time on the market?
Boats of the Beneteau Oceanis 45 had been listed a median of 1,580 days when we last saw them, against 1,653 days for the Jeanneau Sun Odyssey 509. That is time listed so far, not time to sell, which we don't measure yet. 41% of the Beneteau Oceanis 45 boats we saw 14 or more days apart cut their asking price, against 25% of the Jeanneau Sun Odyssey 509 boats.
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. The Gauge Values compare the whole fleets instead, so they mix boats of different ages.
