The next three years
This boat's estimate carried forward along the model's age curve, if the market holds where it is today. The range is today's spread of boats, carried forward.
The curve is fitted on boats up to 54 years old, so we stop there rather than extrapolate.
Keeping this boat one more year costs about £1,000 in value, before berth, insurance and maintenance.

Questions about the 1973 Bertram 28 Flybridge Cruiser
How much is a 1973 Bertram 28 Flybridge Cruiser worth?
A 1973 Bertram 28 Flybridge Cruiser is worth about £26,000 in today's asking prices, most likely between £14,000 and £34,000. Based on 16 comparable boats built between 1970 and 1976, 5 of them in 1973.
What do 1973 Bertram 28 Flybridge Cruisers ask?
The 5 boats built in 1973 that we observed asked a median of £27,000 in today's prices. Each boat is counted once, at its latest asking price; these are asking prices, not sale prices.
Is a 1973 Bertram 28 Flybridge Cruiser cheaper than a 1974?
Yes, usually by about 3.6%: each newer build year of this model asks that much more, all else equal. The gap between individual boats is often larger, because hours, VAT status and where the boat lies move the price too.
How much will it lose next year?
About £1,000, or 3.5%, if the market holds where it is. That rate is fitted on 48 boats across the whole run, not a forecast of the market.
Are these sold prices?
No. Every figure here is built from asking prices seen on public listings. Boats usually sell for less than they ask; we do not yet measure by how much, so we never print a sold price as ours.
