A year of ownership
Each at its Gauge Value, on a South Coast marina berth, 44 engine hours a year (the median of 103 UK-listed sailing boats that report hours). An estimate in pounds from published rates, not a quote.
Each line is the middle of the cited range, to the nearest fifty pounds. Depreciation is a year of age on each model's published curve, at its Gauge Value, and stays out of the totals.
The Tartan 4100 has no published depreciation curve, so its depreciation is withheld.

Which spends less time on the market?
Boats of the Catalina Yachts 42 MkII had been listed a median of 26 days when we last saw them, against 37 days for the Tartan 4100. That is time listed so far, not time to sell, which we don't measure yet. 7% of the Catalina Yachts 42 MkII boats we saw 14 or more days apart cut their asking price, against 0% of the Tartan 4100 boats.
How do you compare them like for like?
We compare boats of the same build year. For each of the 10 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 17 boats in those years. The Gauge Values compare the whole fleets instead, so they mix boats of different ages.
