Catalina Yachts against Oday · used asking prices, listed in the US
At the same age, the Oday 28 asks 19% more than the Catalina 27; on the headline Gauge Values it asks 11% less, which mixes ages: its boats are older (median build year 1983 against 1986). We can't yet say which holds its value better: the Oday 28 has no published depreciation curve.

Head to head
The better figure on each line is in orange. Where either side has too few boats, we say so rather than pick a winner.
Year by year
Each build year's Gauge Estimate, for the 5 years both have boats in. Pooled across those years (8 and 10 boats), the Oday 28 asks 19% more than the Catalina 27.
What your budget buys
At £8,500 your money buys 5 years newer in the Catalina 27: a 1990 against a 1985.
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 Oday 28 has no published depreciation curve, so its depreciation is withheld.
The Catalina 27's asking prices are about level with age on its curve (under 1% a year), so no depreciation figure is printed.
Fuel is left out of both totals: for the Oday 28, fewer than three of its listings give the engine power.

Questions
Which is cheaper, the Catalina 27 or the Oday 28?
At the same age the Catalina 27 is cheaper: the Oday 28 asks 19% more than the Catalina 27 across 5 shared build years. Their Gauge Values, the median asking prices of all the boats we observed whatever their age, are £9,000 and £8,000.
Which holds its value better?
We can't say yet. The Catalina 27's asking prices are about level with age, but the Oday 28 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. We have 12 Oday 28 boats across 6 build years.
Which spends less time on the market?
Boats of the Catalina 27 had been listed a median of 259 days when we last saw them; too few Oday 28 boats were seen on two dates to say. That is time listed so far, not time to sell, which we don't measure yet. 33% of the Catalina 27 boats we saw 14 or more days apart cut their asking price; too few Oday 28 boats were seen that far apart to say.
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 8 boats in those years. The Gauge Values compare the whole fleets instead, so they mix boats of different ages.
