Sigma 33 OODvsWesterly Konsort
Sigma against Westerly · used asking prices, listed in the UK
At the same age, the Westerly Konsort asks about the same as the Sigma 33 OOD; on the headline Gauge Values it asks 3.4% more, which compares the whole fleets rather than boats of the same age. We can't yet say which holds its value better: the Sigma 33 OOD has no published depreciation curve.
same age · 6 shared build years · 8 and 15 boats in them · Indicative · in today’s prices · asking, not sold
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 6 years both have boats in. Pooled across those years (8 and 15 boats), the Westerly Konsort asks about the same as the Sigma 33 OOD.
What your budget buys
At £15,000, only the Westerly Konsort has a build year within reach.
A year of ownership
Each at its Gauge Value, on a South Coast marina berth. 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 each model, fewer than three of its listings give the engine power.

Questions
Which is cheaper, the Sigma 33 OOD or the Westerly Konsort?
At the same age they ask about the same: across 6 shared build years the gap is under one per cent. Their Gauge Values, the median asking prices of all the boats we observed whatever their age, are £14,500 and £15,000.
Which holds its value better?
We can't say yet. The Westerly Konsort loses about 2.0% 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 Sigma 33 OOD had been listed a median of 346 days when we last saw them, against 415 days for the Westerly Konsort. That is time listed so far, not time to sell, which we don't measure yet. 25% of the Westerly Konsort 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 6 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.
