Island Packet 27vsNonsuch 30

Island Packet against Nonsuch · used asking prices, listed in the US

At the same age, the Nonsuch 30 asks 64% more than the Island Packet 27; on the headline Gauge Values it asks 2.1% less, which mixes ages: its boats are older (median build year 1985 against 1987). Neither has a published depreciation curve yet, so we can't say which holds its value better.

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 Island Packet 27 or the Nonsuch 30?

At the same age the Island Packet 27 is cheaper: the Nonsuch 30 asks 64% more than the Island Packet 27 across 6 shared build years. Their Gauge Values, the median asking prices of all the boats we observed whatever their age, are £24,000 and £23,500.

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 16 Island Packet 27 boats across 9 build years. We have 16 Nonsuch 30 boats across 8 build years.

Which spends less time on the market?

Boats of the Island Packet 27 had been listed a median of 36 days when we last saw them, against 143 days for the Nonsuch 30. That is time listed so far, not time to sell, which we don't measure yet. 33% of the Nonsuch 30 boats we saw 14 or more days apart cut their asking price; too few Island Packet 27 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 12 boats in those years. The Gauge Values compare the whole fleets instead, so they mix boats of different ages.
