Lagoon 450vsLagoon 450 S

Two Lagoon models · used asking prices, listed in Europe and the US

At the same age, the Lagoon 450 S asks 18% more than the Lagoon 450; on the headline Gauge Values it asks 23% more, which mixes ages: its boats are younger (median build year 2018 against 2016). We can't yet say which holds its value better: the Lagoon 450 S has no published depreciation curve.

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 Lagoon 450 S has no published depreciation curve, so its depreciation is withheld.

Questions

Which is cheaper, the Lagoon 450 or the Lagoon 450 S?

At the same age the Lagoon 450 is cheaper: the Lagoon 450 S asks 18% more than the Lagoon 450 across 7 shared build years. Their Gauge Values, the median asking prices of all the boats we observed whatever their age, are £324,500 and £400,000.

Which holds its value better?

We can't say yet. The Lagoon 450 loses about 2.0% of its asking price a year of age, but the Lagoon 450 S 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 10 Lagoon 450 S boats across 7 build years.

Which spends less time on the market?

Boats of the Lagoon 450 had been listed a median of 1,668 days when we last saw them, against 24 days for the Lagoon 450 S. That is time listed so far, not time to sell, which we don't measure yet. 63% of the Lagoon 450 boats we saw 14 or more days apart cut their asking price, against 0% of the Lagoon 450 S boats.

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 10 boats in those years. The Gauge Values compare the whole fleets instead, so they mix boats of different ages.
