How much does a used Shamrock cost?

A used Shamrock asks a median of £18,500 across 6 boats listed since Apr 2021, in today's prices. These are asking prices, not sold prices.

Does a Shamrock hold its value?

We don't publish a rate for Shamrock yet. We rate a range once 20 boats across six build years of the same models have been seen. We have 6 Shamrock motor boats across 6 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 Shamrock's own.

Why is a Shamrock model missing a price?
