Questions about West Bay prices

How much does a used West Bay cost?

A used West Bay asks a median of £410,500 across 12 boats listed since Jan 2022, in today's prices. The middle half ask between £362,500 and £442,500. These are asking prices, not sold prices.

Does a West Bay hold its value?

We don't publish a rate for West Bay yet. We rate a range once 20 boats across six build years of the same models have been seen. We have 12 West Bay 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 West Bay's own.

Why is a West Bay model missing a price?

We publish a model once five boats have been listed. 3 models are listed above with their count so far, including the SonShip 64, the SonShip 68 and the SonShip 103, and will get a published figure when they reach five.
