Questions about the 1988 Sea Ray 300 Weekender

How much is a 1988 Sea Ray 300 Weekender worth?

A 1988 Sea Ray 300 Weekender is worth about £12,500 in today's asking prices, most likely between £8,000 and £17,000. Based on 16 comparable boats built between 1986 and 1991, 6 of them in 1988.

What do 1988 Sea Ray 300 Weekenders ask?

The 6 boats built in 1988 that we observed asked a median of £13,500 in today's prices. Each boat is counted once, at its latest asking price; these are asking prices, not sale prices.

Is a 1988 Sea Ray 300 Weekender cheaper than a 1989?

Yes, usually by about 5.2%: 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 £500, or 4.9%, if the market holds where it is. That rate is fitted on 20 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.
