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 Interboat model has 20 boats across six build years yet, so none can be ranked. 2 models have 10 or more boats.

Questions about Interboat prices

How much does a used Interboat cost?

A used Interboat asks a median of £50,000 across 53 boats listed since Sep 2020, in today's prices. The middle half ask between £36,500 and £63,000. These are asking prices, not sold prices.

Does an Interboat hold its value?

Across the range, a used Interboat loses about 1.7% of its asking price for each year of age, against 5.9% for the same types of boat from other builders.

Why is an Interboat model missing a price?

We publish a model once five boats have been listed. 17 models are listed above with their count so far, including the Interboat 20, the Intender 650 and the Interboat 650, and will get a published figure when they reach five.
