Lagoon 450 SvsNautitech 46 Fly
Lagoon against Nautitech · used asking prices, listed in Europe and the US
At the same age, the Nautitech 46 Fly asks 5.3% more than the Lagoon 450 S; on the headline Gauge Values it asks 6.9% less, which compares the whole fleets rather than boats of the same age. Neither has a published depreciation curve yet, so we can't say which holds its value better.

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 10 boats), the Nautitech 46 Fly asks 5.3% more than the Lagoon 450 S.
What your budget buys
At £390,000, only the Lagoon 450 S 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.
Neither model has a published depreciation curve, so depreciation is withheld on both sides.

Questions
Which is cheaper, the Lagoon 450 S or the Nautitech 46 Fly?
At the same age the Lagoon 450 S is cheaper: the Nautitech 46 Fly asks 5.3% more than the Lagoon 450 S across 6 shared build years. Their Gauge Values, the median asking prices of all the boats we observed whatever their age, are £400,000 and £372,500.
Which holds its value better?
We can't say yet: neither has a published depreciation curve, and 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. We have 10 Nautitech 46 Fly boats across 6 build years.
Which spends less time on the market?
Boats of the Lagoon 450 S had been listed a median of 24 days when we last saw them, against 36 days for the Nautitech 46 Fly. That is time listed so far, not time to sell, which we don't measure yet. 0% of the Lagoon 450 S boats we saw 14 or more days apart cut their asking price, against 44% of the Nautitech 46 Fly boats.
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.
