Lagoon 450 FvsNautitech 46 Open

Lagoon against Nautitech · used asking prices, listed in Europe and the US

At the same age, the Nautitech 46 Open asks about the same as the Lagoon 450 F; on the headline Gauge Values it asks 16% more, which mixes ages: its boats are younger (median build year 2018 against 2015). Neither has a published depreciation curve yet, so we can't say which holds its value better.

Year by year

Each build year's Gauge Estimate, for the 4 years both have boats in. Pooled across those years (9 and 10 boats), the Nautitech 46 Open asks about the same as the Lagoon 450 F.

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 F or the Nautitech 46 Open?

At the same age they ask about the same: across 4 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 £385,000 and £447,500.

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 18 Lagoon 450 F boats across 8 build years. We have 16 Nautitech 46 Open boats across 8 build years.

Which spends less time on the market?

Boats of the Lagoon 450 F had been listed a median of 320 days when we last saw them, against 37 days for the Nautitech 46 Open. That is time listed so far, not time to sell, which we don't measure yet. 8% of the Lagoon 450 F boats we saw 14 or more days apart cut their asking price, against 42% of the Nautitech 46 Open boats.

How do you compare them like for like?

We compare boats of the same build year. For each of the 4 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.
