Which hold value best

Share of asking price lost for each year of age. Shorter is better. The tick marks the same type of boat from other builders. Models need 20 boats across six build years, and a consistent fit, to be ranked.

No Duffy model has 20 boats across six build years yet, so none can be ranked. None has 10 boats yet.

Questions about Duffy prices

How much does a used Duffy cost?

A used Duffy asks a median of £71,500 across 12 boats listed since Aug 2020, in today's prices. The middle half ask between £31,500 and £116,500. These are asking prices, not sold prices.

Does a Duffy hold its value?

We don't publish a rate for Duffy yet. We rate a range once 20 boats across six build years of the same models have been seen. We have 11 Duffy motor boats across 9 build years so far. Motor boats from other builders lose about 5.9% a year of age; that is the nearest figure we publish, not Duffy's own.

Why is a Duffy model missing a price?

We publish a model once five boats have been listed. 4 models are listed above with their count so far, including the Cuddy Cabin 22, the Duffy 21 Classic and the Duffy 26, and will get a published figure when they reach five.
