Sea prices and resale values

A used Sea asks a median of £92,000 across 10 boats observed. We need 20 boats across six build years of the same models before we say how fast the range loses value.

Loses a year, across the range

Not enough boats yet

We rate a range once 20 boats across six build years of the same models have been seen. We have 10 Sea motor boats across 8 build years so far.

Nearest figure: motor boats from other builders lose 5.9% a year of age.** A stand-in for the type, not Sea's own figure.

Every model by the build years of the boats we have seen, grouped by range. The figure is the median asking price. Dashed models have too few boats to publish yet.

Questions about Sea prices

How much does a used Sea cost?

A used Sea asks a median of £92,000 across 10 boats listed since Sep 2020, in today's prices. The middle half ask between £72,000 and £106,000. These are asking prices, not sold prices.

Does a Sea hold its value?

We don't publish a rate for Sea yet. We rate a range once 20 boats across six build years of the same models have been seen. We have 10 Sea motor boats across 8 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 Sea's own.

Why is a Sea model missing a price?

We publish a model once five boats have been listed. 30 models are listed above with their count so far, including the Sea 328 Commander, the Sea 208 Bay and the Sea 210, and will get a published figure when they reach five.
