Catalina 30vsSigma 33 OOD
Catalina Yachts against Sigma · used asking prices, listed in the UK and the US
At the same age, the Sigma 33 OOD asks 3.3% more than the Catalina 30; on the headline Gauge Values it asks 7.4% more, which mixes ages: its boats are younger (median build year 1985 against 1984). We can't yet say which holds its value better: the Sigma 33 OOD 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 7 years both have boats in. Pooled across those years (38 and 9 boats), the Sigma 33 OOD asks 3.3% more than the Catalina 30.
What your budget buys
At £14,000, only the Catalina 30 has a build year within reach.
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 Sigma 33 OOD has no published depreciation curve, so its depreciation is withheld.
Fuel is left out of both totals: for the Sigma 33 OOD, fewer than three of its listings give the engine power.

Questions
Which is cheaper, the Catalina 30 or the Sigma 33 OOD?
At the same age the Catalina 30 is cheaper: the Sigma 33 OOD asks 3.3% more than the Catalina 30 across 7 shared build years. Their Gauge Values, the median asking prices of all the boats we observed whatever their age, are £13,500 and £14,500.
Which holds its value better?
We can't say yet. The Catalina 30 loses about 5.1% of its asking price a year of age, but the Sigma 33 OOD 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 9 Sigma 33 OOD boats across 7 build years.
Which spends less time on the market?
Boats of the Catalina 30 had been listed a median of 147 days when we last saw them, against 346 days for the Sigma 33 OOD. That is time listed so far, not time to sell, which we don't measure yet. 31% of the Catalina 30 boats we saw 14 or more days apart cut their asking price; too few Sigma 33 OOD 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 7 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 9 boats in those years. The Gauge Values compare the whole fleets instead, so they mix boats of different ages.
